Abstract

A method of forming a film resistant to blocking including the steps of providing a polymeric film having a first and second surface; applying the anti-blocking agent in a fluid or molten state to at least the first surface of the polymeric film; and gathering the treated film. The anti-blocking agent may be substantially acrylic free.

Claims (21)

1) A method of forming a film resistant to blocking, said method comprising the steps of:
a) providing a polymeric film having a first surface and a second surface, b) applying an anti-blocking agent in a fluid or molten state to at least the first surface of the polymeric film, and c) gathering the treated film to form a gathered film;
wherein the anti-blocking agent is substantially acrylic free.
2) The method of Claim 1 wherein the polymeric film comprises a polymer selected from the group consisting of polyvinylarenes, styrenic block copolymers, polyolefins, metallocene-catalyzed polyolefins, polyesters, polyurethanes, polyether amides, and combinations thereof.
3) The method of Claim 1 wherein the anti-blocking agent comprises a material selected from the group consisting of a phase change solvent, a wax, and combinations thereof.
4) The method of Claim 1 wherein the anti-blocking agent comprises a wax selected from the group consisting of animal-based waxes, vegetable-based waxes, petroleum-based waxes, synthetic waxes, mineral-based waxes, and combinations thereof.
5) The method of Claim 1 wherein the anti-blocking agent comprises a wax which exhibits a property selected from the group consisting of:
a) a Mettler drop point equal to or greater than about 60°C, b) a density from about 0,85 to about 0.98 g/cm3, c) a melt index at 190°C from about 1g to about 5,000 g per 10 minutes, and d) combinations thereof.
6) The method of Claim 1 wherein the step of applying the anti-blocking agent in a fluid or molten state further comprises applying the anti-blocking agent as a fine mist; said fine mist having an average particle diameter of less than or equal to 1000 µm.
7) The method of Claim 1 further comprising the step of cooling the treated film; wherein the step of cooling is performed prior to the step of gathering the treated film.
8) The method of Claim 1 further comprising the step of consolidating the treated film wherein the anti-blocking agent and polymeric film are compressed together; wherein the step of consolidating is performed prior to the step of gathering the treated film.
9) The method of Claim 1 further comprising the step of storing the gathered film for a dwell time of at least about 24 hours.
10) The method of Claim 1 further comprising the step of separating the gathered film, said separation results in the detachment of at least some portion of the gathered film that was in contact with itself and wherein the separation requires an average T-Peel force of less than or equal to about 20 N/cm.
11) The method of Claim 10 further comprising the step of laminating the separated film to a substrate to form a film laminate.
12) The method of Claim 10 further comprising the step of incorporating the separated film into a diaper.
13) A treated film produced in accordance to the process of Claim 1.
14) A treated film comprising:
a) a polymeric film having a first surface and a second surface; and b) an anti-blocking agent disposed on at least the first surface of the polymeric film;
wherein said treated film exhibits an average T-Peel force of less than or equal to about 20 N/cm and wherein the anti-blocking agent is substantially acrylic free.
15) The treated film of Claim 14 wherein the polymeric film comprises a polymer selected from the group consisting of polyvinylarenes, styrenic block copolymers, polyolefins, metallocene-catalyzed polyolefins, polyesters, polyurethanes, polyether amides, and combinations thereof.
16) The treated film of Claim 14 wherein the polymeric film is an elastomeric film.
17) The treated film of Claim 14 wherein the treated film is incorporated in to a diaper element selected from the group consisting of a side panel, a backsheet, a leg cuff, a waist feature, a fastening system, and combinations thereof.
18) The treated film of Claim 14 wherein the anti-blocking agent comprises a material selected from the group consisting of a phase change solvent, a wax, and combinations thereof.
19) The method of Claim 14 wherein the anti-blocking agent comprises a wax selected from the group consisting of animal-based waxes, vegetable-based waxes, petroleum-based waxes, synthetic waxes, mineral-based waxes, and combinations thereof.
20) The method of Claim 14 wherein the anti-blocking agent comprises a wax which exhibits a property selected from the group consisting of:
a) a Mettler drop point equal to or greater than about 60°C, b) a density from about 0.85 to about 0.98 g/cm3, c) a melt index at 190°C from about 1g to about 5,000 g per 10 minutes, and d) combinations thereof.
21) A diaper having a front waist region, a rear waist region, and a crotch region positioned between the front and rear waist regions; said diaper comprising:
a) a liquid pervious topsheet;
b) a backsheet at least partially joined to said topsheet;
c) an absorbent core positioned between said topsheet and backsheet;
d) at least one element selected from the group consisting of a pair of side panels, a pair of leg cuffs, a waist feature, a fastening system, and combinations thereof;
wherein said element comprises a treated film, said treated film comprising:
i) an polymeric film having a first surface and a second surface; and ii) an anti-blocking agent disposed on at least one surface of the polymeric film;
wherein said treated film exhibits an average T-Peel force of less than or equal to about 20 N/cm and wherein said anti-blocking agent is substantially acrylic free.
