Definitions
- Elastomeric materials have the ability to expand to fit over or around an object, and then retract to provide a snug fit around the object.
- Elastomeric materials can be used in garments to provide a snug fit, such as in active wear.
- Elastomeric materials can also form resilient and effective barriers, such as in the cuffs of thermal garments intended to retain body heat.
- Elastomeric materials can be used in the waist, around the leg openings, and in the fasteners (for a diaper) or sides (for an underpants-type garment).
- the elastomeric materials in these regions can improve the overall fit of the garment, and also make it much easier to both don and remove the garment.
- the elastomeric materials also act as resilient barriers, improving the containment capabilities of the garment while still allowing comfort and free movement to the wearer.
- Elastomeric materials can be expensive and producing thin films of expensive material can therefore reduce cost.
- producing thin films can be complicated due to tearing and pinholing.
- Some embodiments of the present invention relate to an elastomeric film comprising a layer comprising (i) at least one olefin-based elastomeric polymer, and (ii) at least one draw down polymer.
- the elastomeric film has a basis weight of no more than about 25 gsm and has a permanent set of no more than about 15% after recovery from being stretched to 100% of its original size.
- inventions include a multilayer elastomeric film with two or more layers comprising (1) a first layer comprising (a) at least one olefin-based elastomeric polymer and (b) at least one first draw down polymer, and (2) a second layer comprising (a) at least one elastomeric polymer and (b) at least one second draw down polymer.
- the multilayer elastomeric film has a basis weight of no more than about 40 gsm and has a permanent set of no more than about 15% after recovery from being stretched to 100% of its original size.
- At least one elastomeric polymer of the second layer can be an olefin-based elastomeric polymer, a non-olefin-based elastomeric polymer, or combinations thereof.
- Other embodiments include a multilayer elastomeric film that further comprises a third layer comprising at least one second elastomeric polymer and at least one third draw down polymer.
- Some embodiments of the invention include a laminate comprising a film that can be a monolayer elastomeric film or a multilayer elastomeric film and at least one substrate. The film and the substrate are laminated together to form the laminate.
- Further embodiments include a method for making an elastomeric film comprising extruding a mixture into a layer of a film.
- the mixture comprises at least one olefin-based elastomeric polymer and at least one draw down polymer.
- Some embodiments include a method for making a multilayer elastomeric film with at least two layers comprising coextruding a first layer and a second layer.
- the first layer comprises at least one olefin-based elastomeric polymer and at least one first draw down polymer.
- the second layer comprises at least one elastomeric polymer and at least one second draw down polymer.
- inventions include a method for making a multilayer elastomeric film with at least three layers comprising coextruding a first layer, a second layer, and a third layer.
- the first layer comprises at least one olefin-based elastomeric polymer and at least one first draw down polymer.
- the second layer comprises at least one elastomeric polymer and at least one second draw down polymer.
- the third layer comprises at least one second elastomeric polymer and at least one third draw down polymer.
- Some embodiments include a method for making a laminate comprising laminating a film to at least one substrate.
- the film is an elastomeric film or a multilayer elastomeric film.
- Figure 1 is a schematic of a typical cast coextrusion process
- Figure 2 is a schematic of a typical adhesive lamination process
- Figure 3 is a schematic of a typical extrusion coating process.
- Frm refers to material in a sheet-like form where the dimensions of the material in the x (length) and y (width) directions are substantially larger than the dimension in the z (thickness) direction.
- Basis weight is an industry standard term that quantifies the thickness or unit mass of a film or laminate product.
- the basis weight is the mass per planar area of the sheet-like material. Basis weight is commonly stated in units of grams per square meter (gsm) or ounces per square yard (osy).
- Coextrusion refers to a process of making multilayer polymer films.
- each polymer or polymer blend comprising a layer of the film is melted by itself.
- the molten polymers may be layered inside the extrusion die, and the layers of molten polymer films are extruded from the die essentially simultaneously.
- coextruded polymer films the individual layers of the film are bonded together but remain essentially unmixed and distinct as layers within the film. This is contrasted with blended multicomponent films, where the polymer components are mixed to make an essentially homogeneous blend or heterogeneous mixture of polymers that are extruded in a single layer.
- Laminate refers to a layered structure of sheet-like materials stacked and bonded so that the layers are substantially coextensive across the width of the narrowest sheet of material.
- the layers may comprise films, fabrics, other materials in sheet form, or combinations thereof.
- a laminate may be a structure comprising a layer of film and a layer of fabric bonded together across their width such that the two layers remain bonded as a single sheet under normal use.
- a laminate may also be called a composite or a coated material.
- “Laminate” as a verb refers to the process by which such a layered structure is formed.
- Extrusion lamination or “extrusion coating” refer to processes by which a film of molten polymer is extruded onto a solid substrate, in order to coat the substrate with the molten polymer film to bond the substrate and film together.
- Elastomeric or “elastomer” refer to polymer materials which can be stretched to at least about 150% or more of their original dimension, and which then recover to no more than about 120% of their original dimension in the direction of the applied stretching force.
- an elastomeric film that is 10 cm long should stretch to at least about 15 cm under a suitable stretching force, and then retract to no more than about 12 cm when the stretching force is removed.
- Elastomeric materials are both stretchable and recoverable.
- Permanent set is the permanent deformation of a material after removal of an applied load. In the case of elastomeric films, permanent set is the increase in length of a sample of a film after the film has been stretched to a given length and then allowed to relax.
- Permanent set is typically expressed as a percent increase relative to the original size. For example, if a 10 cm piece of elastomeric film is stretched to 20 cm, then allowed to relax, and the resulting relaxed film is 11.5 cm in length, the permanent set of the film is 15%.
- the test method used to measure permanent set is based upon ASTM D882- 97 with the following details.
- the sample is cut to make one inch by six inch specimens - the six inch length is in the direction the of the film or laminate is being tested (e.g., in the CD direction for the examples below).
- An MTS Tensile Tester (Qtest) is used to measure the sample deformation.
- the tester grip faces are rubber grip faces that are 25 mm wide (MTS part No. 56163829).
- the sample is loaded with a grip distance set at two inches from the center of upper grip face to the center of the lower grip face.
- the strain endpoint is set to 100%.
- the first upload cycle is run at a rate of 20 inches/minute to the strain endpoint, then immediately returns to 0% strain at a rate of 20 inches/minute, and then is held at 0% strain for 30 seconds.
- the second upload cycle is run at a rate of 20 inches/minute to the strain endpoint, and then immediately returns to 0% strain at a rate of 20 inches/minute.
- the permanent set is calculated at the point when load reaches eight grams of force during the second upload cycle.
- “Stretchable” and “recoverable” are descriptive terms used to describe the elastomeric properties of a material.
- “Stretchable” means that the material can be extended by a pulling force to a specified dimension significantly greater than its initial dimension without breaking. For example, a material that is 10 cm long that can be extended to about 13 cm long without breaking under a pulling force could be described as stretchable.
- “Recoverable” means that a material which is extended by a pulling force to a certain dimension significantly greater than its initial dimension without breaking will return to its initial dimension or a specified dimension that is adequately close to the initial dimension when the pulling force is released. For example, a material that is 10 cm long that can be extended to about 13 cm long without breaking under a pulling force, and which returns to about 10 cm long or to a specified length that is adequately close to 10 cm could be described as recoverable.
- Extensible refers to polymer materials that can be stretched at least about 130% of their original dimension without breaking, but which either do not recover significantly or recover to greater than about 120% of their original dimension and therefore are not elastomeric as defined above.
- an extensible film that is 10 cm long should stretch to at least about 13 cm under a stretching force, then either remain about 13 cm long or recover to a length more than about 12 cm when the stretching force is removed.
- Extensible materials are stretchable, but not recoverable.
- activation refers to a process by which the elastomeric film or material is rendered easy to stretch. Most often, activation is a physical treatment, modification or deformation of the elastomeric film. Stretching a film for the first time is one means of activating the film. An elastomeric material that has undergone activation is called “activated.” A common example of activation is blowing up a balloon. The first time the balloon is inflated (or “activated"), the material in the balloon is stretched. If the inflated balloon is allowed to deflate and then blown up again, the "activated" balloon is much easier to inflate.
- Film strength or “mechanical strength” are the tensile properties of a film or laminate, as measured by ASTM D-822 "Tensile Properties of Thin Plastic Sheeting.” Unless noted otherwise, “film strength” or “mechanical strength” refers specifically to tensile at break and % elongation at break.
- Tear strength is a property of a film which determines the ease or difficulty by which the film can be torn starting from a notch or aperture cut into the film, as measured by the notched Elmendorf test, ASTM D-1922.
- Bond strength is a property of a laminate comprising two or more layers. The bond strength is determined by measuring the force required to peel apart the laminate layers after they are bonded together. Bond strength can be measured by methods such as ASTM D- 1876 or ASTM F-904. * “Pinholing” refers to the formation of small holes or tears in a film while the film is being formed, laminated, activated, or other manufacturing or processing step. “Pinholes” are the small holes or tears so formed. Pinholes are typically in the range of about 100 ⁇ m to 1 cm in size.
- Blocking refers to the phenomenon of a material sticking to itself while rolled, folded, or otherwise placed in intimate surface-to-surface contact, due to the inherent stickiness or tackiness of one or more of the material components. Blocking can be quantified by ASTM D3354 "Blocking Load of Plastic Film by the Parallel Plate Method.”
- a film which resists tearing under a given stress is described as 'more robust' than another film which tears under equivalent stress.
- an elastomeric film with a low basis weight can be produced.
- the elastomeric film is a monolayer film of a polyolefin-based layer.
- the elastomeric film can also be a multilayer film having a polyolefin-based layer.
- the multilayer film can have a total of, for example, two layers, three layers, four layers, five layers, six layers, seven layers, or eight or more layers.
- the elastomeric film can also be part of a laminate formed with one or more substrates, such as nonwoven fabrics.
- the monolayer elastomeric film comprises a polyolefin-based layer that comprises one or more olefin-based elastomeric polymers blended with one or more draw down polymers.
- the draw down polymer is a polymer that adds or enhances one or more film properties or processing properties, such as those that aid in processability during film preparation.
- the draw down polymer can aid in the production of reduced-gauge (i.e., thin) films.
- the draw down polymer can aid in the film extrusion, such as by helping to provide an increased line speed or reduce draw resonance.
- draw down polymer can act as a processing aid that lubricates the die to reduce sticking (e.g., of elastomeric polymers) and flow resistance of the molten elastomeric resin.
- the addition of the draw down polymer can provide one or a combination of these aids to film extrusion or processability.
- draw down polymers There are many examples of draw down polymers.
- a linear low-density polyethylene e.g., ELITETM 5800 provided by Dow Chemical Corp. of Midland, MI
- ELITETM 5800 provided by Dow Chemical Corp. of Midland, MI
- High- impact polystyrene e.g., STYRONTM 485 from Dow Chemical Corp. of Midland, MI
- IneosNova 473D from IneosNova of Channahon, IL
- Polypropylene can improve the robustness of the elastomer and improve the films' resistance to pinholing and tearing.
- hPP Homopolymer polypropylene
- hPP Homopolymer polypropylene
- hPP is a form of polypropylene which is highly crystalline and containing essentially 100% propylene monomer.
- hPP is added to a layer comprising an elastomeric polymer (e.g., styrene block copolymers), as discussed below; the addition can result, in some instances, in a film that can be extruded at a thinner gauge, with improved gauge uniformity, or with reduced tendency to experience draw resonance during extrusion.
- an elastomeric polymer e.g., styrene block copolymers
- the draw down polymers can be linear low density polyethylene, propylene, homopolymer polypropylene, high impact polystyrene, and mixtures thereof.
- the draw down polymer can be a polymer which has been prepared using a single-site catalyst such as a metallocene catalyst and can be, for example, a polyolefin produced using a metallocene catalyst (e.g., ELITETM 5800 provided by Dow
- the identity and amount of draw down polymer can depend on the other components in the layer (e.g., the identity of the olefin- based elastomeric polymer(s) in the layer), other components of the film or, if applicable, components of the laminate that comprises the film.
- the total amount of draw down polymer can be present in an amount effective to enhance one or more film properties that aid in processability during film preparation; for example, the total amount of draw down polymer can be present in an amount effective to provide a film gauge of about 25 gsm, about 20 gsm, about 15 gsm, or about 10 gsm.
- the total amount of draw down polymer (i.e., the combined amount of the one or more draw down polymer(s)) can be about 5%, about 10 wt%, about 15 wt%, about 20 wt%, about 25 wt%, about 30 wt%, about 35 wt%, about 40 wt%, or about 45 wt%.
- the wt% is relative to the layer weight (i.e., total weight of draw down polymer(s) divided by the total weight of the layer). In some instances the total amount of the draw down polymer is at least about 5 wt%, at least about 10 wt%, or at least about 15 wt%.
- the total amount of draw down polymer can be no more than about 20 wt%, no more than about 25 wt%, no more than about 30 wt%, no more than about 35 wt%, or no more than about 45 wt%.
- the olefin-based elastomeric polymer can be olefin block copolymer, olefin random copolymer, ethylene copolymer, propylene copolymer, or mixtures thereof.

- the nonwoven fabrics can include fibers or can be made from fibers that have a cross section perpendicular to the fiber longitudinal axis that is substantially non-circular.
- substantially non-circular means that the ratio of the longest axis of the cross section to the shortest axis of the cross section is at least about 1.1.
- the ratio of the longest axis of the cross section to the shortest axis of the cross section can be about 1.1, about 1.2, about 1.5, about 2.0, about 3.0, about 6.0, about 10.0, or about 15.0. In some embodiments, this ratio can be at least about 1.2, at least about 1.5, or at least about 2.0.
- These ratios can be, for example, no more than about 3.0, no more than about 6.0, no more than about 10.0, or no more than about 15.0.
- the shape of the cross section perpendicular to the fiber longitudinal axis of the substantially non-circular fibers can be rectangular (e.g., with rounded corners) which are also referred to as "flat" fibers, trilobal, or oblong (e.g., oval) in the cross section.
- These substantially non-circular fibers can provide more surface area to bond to the elastomeric film than nonwoven fabrics with fibers that are circular in cross section. Such an increase in surface area can increase the bond strength between the elastomeric film and fibers.
- Bond strength between the elastomeric film and the substrate layers of the laminate can be measured by any number of methods, including, for example, ASTM D-1876.
- optimum bond strength is a balance between bond strength that is too low (e.g., that can lead to delamination of the film from the substrate) and bond strength that is too high (e.g., that can lead to inelastic behavior of the laminate, even when activated).
- Bonding between the layers can be achieved by any method, including, but not limited to, adhesive bonding, extrusion lamination, thermal bonding, ultrasonic bonding, calendering, point bonding, laser bonding, and combinations thereof.
- the bonding strength can depend on the bonding method and variations within a given bonding method. For example, for layers bonded by an adhesive, the choice of adhesive and the amount of adhesive applied to bond the layers can be adjusted to achieve the desired bond strength.
- Bonding can also occur between the substrate layer (e.g., nonwoven) and the elastomeric film during extrusion by heating the film to be molten; this molten film is pressed into the substrate layer to embed the substrate into the film to create bonding. In some instances, this bonding can be enhanced if the chemical composition of the elastomeric film has a chemical affinity for the chemical composition of the substrate layer.
- the elastomeric film is a multilayer film
- chemical affinity relative to the substrate layer relates to the layer of the multilayer film that is in contact with the substrate.
- the substrate is a multilayer substrate or a bicomponent substrate
- chemical affinity relative to the film relates to the substrate component that is in contact with the film.
- the temperature of the extruded molten elastomeric web can be controlled.
- the extruded web has less mass to retain heat during the extrusion process. Less mass can result in an extruded molten polymer web that can solidify rapidly. An extruded polymer film that solidifies too rapidly can sometimes result in weaker bond strength because less embedding of the substrate in the extruded elastomeric film can occur. In some instances, the bond strength is further decreased when the extruded polymer does not have great chemical affinity for the materials that comprise the substrate.
- film layers comprising SBC do not have strong natural chemical affinity for the polyolefinic substrate materials.
- sheets of films comprising SBC and substrates with fibers sometimes rely on mechanical bonding forces, such as those achieved by embedding the substrate fibers into the surface of the film. If the film has solidified before contacting the substrate, the fibers cannot be sufficiently embedded into the solidified surface of the film. Hence, the bond strength between the film and substrate of the laminate can be poor, and the elastomeric material can sometimes delaminate easily. Bond strength can be enhanced by other bonding means, such as application of an adhesive.
- bond strength can be enhanced by using a multilayer film that includes one layer with a less compatible polymer (e.g., SBC) and one or more layers with a polymer that is more compatible (e.g., an olefin-based elastomeric polymer).
- a less compatible polymer e.g., SBC
- a polymer that is more compatible e.g., an olefin-based elastomeric polymer
- laminates having films comprising elastomers that are chemically similar to the substrate composition can have increased bonding strength when the substrate is embedded into the film during extrusion.
- films comprising polyolefins can have chemical affinity for substrates that comprise polyolefins and can therefore have increased bonding strength.
- the chemical affinity e.g., when the film and the substrate comprise polyolefins
- the film and the substrate comprise polyolefins can provide substantial bonding even if there is little or no mechanical bonding (e.g., from embedded fibers in the film).
- the film is soft or semi-molten when it contacts the substrate, this can lead to enhanced bonding via mechanical bonding.
- other methods of bonding e.g., adhesive bonding
- olefin-based elastomeric films do not solidify as rapidly as SBC-based materials.
- the extruded olefin-based elastomeric web can be semi- molten and soft when it contacts the nonwoven fibers, which allows the fibers to embed into the surface.
- olefin-based elastomeric films, or multilayer elastomeric films with olefin-based elastomeric skins can form laminates with stronger bond strength and less tendency to delaminate.
- the chemical affinity of the elastomeric film may be sufficiently high that an acceptable bond strength is obtained, but the laminate may be difficult to activate due to a number of factors that may include, for example, the intimate coupling of the nonwoven substrate and the film which can hinder the activation process.
- the high chemical affinity of the elastomeric film for the nonwoven can sometimes result in roll blocking and thus can sometimes cause problems in storing, transporting, and unwinding of the laminate. Such roll blocking can be addressed by appropriate measures as described herein or by any appropriate method.
- One method of forming the laminate is adhesive lamination, illustrated in Fig.
- the elastomeric film 20 is melt-extruded from a film-forming die 18 and drops to the nip between the illustrated metal roll 30 and backing roll 32.
- the metal roll 30 may be chilled to rapidly cool the molten film.
- the metal roll may also be engraved with an embossing pattern if such a pattern is desired on the resulting film.
- adhesive 34 is applied by means such as a spray unit 35 onto the film.
- the spray unit 35 may spray adhesive onto the incoming fabric 13.
- the fabric 13 is unwound from roll 11 and introduced into a nip 37 that presses the elastomeric film 22 and the fabric 13 to bond them together.
- the laminate 24 may now be wound into a roll or go on for further processing.
- an extrusion coating process is used to form the laminate.
- Fig. 3 illustrates an extrusion coating process.
- a film 20 is melt- extruded through a film-forming die 18 and drops to the nip between the illustrated metal roll 30 and backing roll 32.
- the metal roll may be chilled to rapidly cool the molten polymer film.
- the metal roll 30 may also be engraved with an embossing pattern if such a pattern is desired on the resulting film.
- the fabric 13 of the laminate is unwound from roll 11 and introduced into the nip between the metal and rubber rolls as well.
- the extruded film 20 and fabric 13 are pressed together at the nip to bond them together.
- the laminate 24 may now be wound into a roll or go on for further processing.
- Additional processing steps such as activating the elastomeric laminate, aperturing the laminate, printing the laminate, slitting the laminate, laminating additional layers to the laminate, and other such processes can be added to the process.
- the laminate can be activated by stretching means.
- Machine-direction orientation can be used to activate laminate in the machine direction, while tentering can activate laminates in the cross direction.
- Incremental stretching rollers can be used to activate laminates in the machine direction, cross direction, at an angle, or any combination thereof.
- the depth of engagement used for incremental stretching is about 0.05 inches, about 0.10 inches, about 0.15 inches, about 0.20 inches, or about 0.25 inches.
- the depth of engagement can be, for example, at least about 0.05 inches or at least about 0.10 inches.
- the depth of engagement can be, for example, no more than about 0.10 inches, no more than about 0.18 inches, or no more than about 0.25 inches.
- Laminates of elastomeric films and fabrics are particularly suited to activation by incremental stretching. As disclosed in the commonly-assigned patent
- Example 1 Elastomeric laminates of the present invention were prepared and tested.
- the laminates comprised a monolayer elastomeric film and two layers of nonwoven fabric.
- the monolayer elastomeric films comprised 80% VISTAMAXXTM 6102 polyolefinic elastomer, from ExxonMobil Chemical, 15% ELITETM 5800 linear low density polyethylene from The Dow Chemical Company, and 5% white masterbatch concentrate (Schulman 8500) from Schulman Corporation.
- the elastomeric film monolayers were extruded on a cast-extrusion line. Films with target basis weights of less than 20 gsm, and as low as 14 gsm, were extruded with little or no draw resonance, with no web breakage, and with basis weight fluctuation of less than 20%.
- Elastomeric laminates of the present invention were prepared and tested.
- the laminates comprised two layers of nonwoven fabric and a multilayer ABA elastomeric film, where the ABA layers were about 25%/50%/25% of the overall multilayer film composition.
- the A (skin) layers comprised 75% VISTAMAXXTM 6102 polyolefinic elastomer, 15% ELITETM 5800 linear low density polyethylene, 5% INSPIRETM D118.01 homopolymer polypropylene from The Dow Chemical Company, and 5% ALATHON® m6060 high-density polyethylene, from Equistar Chemicals.
- the B (core) layers comprised 75% VECTORTM 421 IA styrene-isoprene-styrene (SIS) block copolymer (from Dexco Polymer LP of Houston Texas), 15% ELITETM 5800 linear low density polyethylene, 5% INSPIRETM D118.01 homopolymer polypropylene, and 5% white masterbatch concentrate (Schulman 8500) from Schulman Corporation.
- the multilayer elastomeric films were extruded on a cast- extrusion line. Films with target basis weights of less than 20 gsm, and as low as 10 gsm, were extruded with little or no draw resonance, with no web breakage, and with basis weight fluctuation of less than 20%.
- This film was extrusion laminated to two layers of 10 gsm flat-fiber bicomponent PE/PP nonwoven fabric (SPUNBONDED BICO 10 GSM with bilobal ⁇ Papillon' Filaments) from ALBIS Nonwoven Fabrics of Aschersleben, Germany.
- the laminates were then activated by incremental stretching at a depth of engagement of 0.100 inches for the intermeshing rolls.
- the thin elastomeric film laminates showed good stretch and recovery characteristics, and the laminates were resistant to pinholes and tearing.
- Example 3 Two SMMS nonwoven (spunbond-meltblown-meltblown-spunbond) layers made by Fibertex Nonwovens A/S of Aalborg, Denmark with a basis weight of 10 gsm each were extrusion laminated to a monolayer elastomeric film on both surfaces.
- the elastomeric film comprised 78% VISTAMAXXTM 6102 from ExxonMobil Company, 15% linear low density polyethylene (LLDPE) (ELITE 5800 from Dow Chemical Company), 5% white master batch (Schulman 8500), and 2% processing aid (LUVOFILM 9679 from Lehmann & Voss & Co. of Hamburg Germany) to make a white elastic film.
- the film was drawn down to 20 gsm to make the extrusion laminated composite of total basis weight of 40 gsm (i.e., 10 gsm nonwoven + 20 gsm film + 10 gsm nonwoven).
- the same laminate was made except that the film was made without adding LLDPE; the film comprised 93% VISTAMAXXTM 6102, 5% white master batch, and 2% processing aid.
- This film could only draw down to 46 gsm to make extrusion laminate of total basis weight of 66 gsm (i.e., 10 gsm nonwoven + 46 gsm film+10 gsm nonwoven). Attempts to draw down this formulation below 46 gsm caused the web to tear.
- Table 1 shows properties of films made from an olefin-based elastomeric polymer, ethylene-octene olefin block copolymer (INFUSETM 9107), with varying amounts of a draw down polymer, LLDPE (ELITETM 5800).
- Sample 4-A shows that the web tears off during extrusion when produced at line speeds of 210 fpm and higher.
- samples 4-B and 4-C show that films can be made that are significantly thinner and that also provide a percent permanent set between 10% and 11.5%.
- Elastomeric laminates of the present invention were prepared and tested.
- the laminates comprised one layer of nonwoven fabric and an ABA elastomeric film, where the ABA layers were about 12%/76%/12% of the overall film composition.
- the A (skin) layers comprised 84% INFUSETM 9107 polyolefinic elastomer, 15% ELITETM 5800 linear low density polyethylene, and 1% processing aid (LUVOFILM 9679 from Lehmann & Voss & Co. of Hamburg Germany).
- the B (core) layers comprised 100% VISTAMAXXTM 6102.
- the elastomeric films were extruded on a cast-extrusion line. The films had basis weights of 25 gsm.
- This film was extrusion laminated to one layer of 18 gsm (70/30 core/sheath) bicomponent spunbond, produced at Fiberweb (Washougal, Washington). Laminates were activated by incremental stretching with CD activation at a depth of engagement of 0.140 inches or 0.160 inches. No pinholes were observed with any of the laminates.
- Elastomeric laminates of the present invention were prepared and tested.
- the laminates comprised one layer of nonwoven fabric and an ABA elastomeric film, where the ABA layers were about 12%/76%/12% of the overall film composition.
- the A (skin) layers comprised 69% INFUSETM 9107 polyolefinic elastomer, 30% ELITETM 5800 linear low density polyethylene, and 1% processing aid (LUVOFILM 9679 from Lehmann & Voss & Co. of Hamburg Germany).
- the B (core) layers comprised 100% VISTAMAXXTM 6102.

- This film was extrusion laminated to one layer of 18 gsm (70/30 core/sheath) bicomponent spunbond, produced at Fiberweb (Washougal, Washington). Laminates were activated by incremental stretching with CD activation at a depth of engagement of 0.140 inches or 0.160 inches. No pinholes were observed with any of the laminates.
- Elastomeric laminates revealed the use of the skin layers as tie layers to achieve good bond strength for a variety of nonwovens with flat fiber webs, round fiber webs, BICO fibers with mixed PE and PP, or sheath/core of PE/PP.
- the skin layer of the elastomeric film was ethylene-propylene elastomer rich with polypropylene.
- the skin layer of the film included an elastomeric polymer that comprised hard and soft segments of ethylene block polymer.
- the data showed that using films with skin (e.g., tie) layers of ethylene block polymer in contact with ethylene nonwoven or bico nonwoven can enhance the bond strength.
- the data also showed that using films with skin (e.g., tie) layers with propylene-rich ethylene-propylene elastomer can bond better to polypropylene nonwovens.
- embodiments of the present invention include elastomeric films with a low basis weight and methods for making the elastomeric films.
- the elastomeric film is a monolayer film of a polyolefin-based layer.
- the elastomeric film can also be a multilayer film having a polyolefin-based layer.
- the elastomeric film can also be part of a laminate formed with one or more substrates, such as nonwoven fabrics.
- the choice of components e.g., draw down polymers, olefin-based elastomeric polymers, and other elastomeric polymers
- component amounts in the layers of the elastomeric film can confer both beneficial film properties and film processing properties.
