Abstract
The present invention relates generally to a packaging container formed of a packaging material comprised of a textile layer of woven polyester fabric and a thermoplastic layer of polyolefin.
Description
- This application claims priority to and the benefit of prior filed U.S. Provisional Patent Application Serial No. 60/310,771, filed Aug. 8, 2001, hereby incorporated by reference herein.
- The present invention relates generally to materials for packaging pouches, and the packaging containers formed therefrom.
- FIG. 1 is an enlarged cross-sectional view of an embodiment of packaging material of the present invention.
- FIG. 2 is a view of a packaging container formed from the packaging material in FIG. 1.
- FIG. 3 is a plan view of a lay-out of packaging material in FIG. 1 for forming the packaging container in FIG. 2.
- FIG. 4 is a section view of the packaging container shown in FIG. 2 which was taken along
section line 4 of FIG. 2. - Referring now to the Figures, and in particular to FIG. 1, there is shown an enlarged cross-sectional view of an embodiment of
packaging material 100 of the present invention. Thepackaging material 100 generally includes atextile layer 110 and athermoplastic layer 120. - As illustrated in FIG. 1, the
textile layer 110 is a woven polyester fabric. The warp yarns of thetextile layer 110 can be 1/150/48 or 50 denier textured polyester yarn, and the fill yarns can be 1/150/48 or 50 denier textured polyester yarn. In one embodiment, the weave density of the fabric ranges from about 50 to about 64 yarns per inch. - Also as illustrated in FIG. 1, the
thermoplastic layer 120 is a polyolefin. In one embodiment, the polyolefin can be a polyethylene, such as metallocene catalyzed low density polyethylene. In another embodiment, the polyolefin can be polypropylene. In a preferred embodiment, thethermoplastic layer 120 will have a softening point temperature lower than thetextile layer 110. In a further preferred embodiment, the softening point of thethermoplastic layer 120 is at least about 40 C. lower than thetextile layer 110. Thethermoplastic layer 120 can range in thickness from about 1.5 to about 4.0 mils, more preferably from about 2 to about 3 mils. In one embodiment, thethermoplastic layer 120 is about 3 mils thick. Thethermoplastic layer 120 can be joined with thetextile layer 110 through lamination, extrusion coating, bonding with a bonding agent, or the like. - The
textile layer 110 can be treated with a water repellant, such as a fluorochemical, to provide the exterior of thetextile layer 110 with a water and/or stain resistance. - Various other treatments can be incorporated into the
textile layer 110, incorporated into thethermoplastic layer 120, and/or disposed over thetextile layer 110 of thematerial 100, such as antimicrobial agents, antibacterial agents, antifungal agents, flame retardants, UV inhibitors, antioxidants, coloring agents, lubricants, fragrances, antistatic agents, or the like. - Referring now to FIG. 2, there is illustrated a
packaging container 200 formed from thepackaging material 100 in FIG. 1. Thepackaging container 200 generally includes abottom 210,side walls 220, and anopen end 230. As shown in FIG. 3, thepackaging container 200 can be formed by folding a rectangular section of thepackaging material 100 and applying heat to theedges 250 to form the container shape. Thepackaging material 100 shown in FIG. 3 is oriented with thethermoplastic layer 120 facing up and thetextile layer 110 facing down. Thepackaging material 100 is folded along fold line B-B′ such that fold line B-B′ protrudes upwardly (out of the page). Thepackaging material 100 is then folded along fold lines A-A′ and C-C′ such that each of the fold lines A-A′ and C-C′ protrude downwardly (into the page). As shown in FIGS. 2 through 4, after the container shape is formed, aclosure 240 can be positioned inside theopen end 230 of thecontainer 200, and secured by applying heat to thecontainer 200 along theopen end 230. Theclosure 240 can be a rail fastener, rail fastener with slider, press to close, zipper, hook and loop, or the like. - In a further embodiment, as shown in FIG. 4, the
textile layer 110 of thematerial 100 can be removed in thegusset areas 261 and 262 prior to forming thecontainer 200, in order to form gussets in thebottom 210 of thecontainer 200 for added support. In one embodiment, thepackaging material 100 has a sufficient stiffness that thecontainer 200 can stand on thebottom 210 without thematerial 100 folding over in the areas of thesides 220.
