- 6. The packaging container of claim 1, wherein the thermoplastic layer of polyolefin has a softening point temperature lower than the textile layer of woven polyester fabric.
- 7. The packaging container of claim 1, wherein the thermoplastic layer of polyolefin has a softening point temperature at least about 40 degrees C. lower than the textile layer of woven polyester fabric.
- 8. The packaging container of claim 1, wherein the thermoplastic layer of polyolefin has a thickness in a range from about 1.5 to about 4.0 mils.
- 9. The packaging container of claim 1, wherein the thermoplastic layer of polyolefin has a thickness in a range from about 2 to about 3 mils.
- 10. The packaging container of claim 1, wherein the thermoplastic layer of polyolefin has a thickness of about 3 mils.
- 11. The packaging container of claim 1, wherein the thermoplastic layer of polyolefin is joined to the textile layer of woven polyester fabric through lamination, extrusion coating, or bonding with a bonding agent.
- 12. The packaging container of claim 1, wherein the textile layer of woven polyester fabric is treated with one or more chemicals selected from the group consisting of water repellant or stain resistant agents, antimicrobial agents, antibacterial agents, antifungal agents, flame retardants, UV inhibitors, antioxidants, coloring agents, lubricants, fragrances, and antistatic agents.
- 13. The packaging container of claim 12, wherein the water repellant or stain resistant agent is a fluorochemical.
- 14. The packaging container of claim 1, wherein the thermoplastic layer of polyolefin is treated with one or more chemicals selected from the group consisting of antimicrobial agents, antibacterial agents, antifungal agents, flame retardants, UV inhibitors, antioxidants, coloring agents, lubricants, fragrances, and antistatic agents.
- 15. The packaging container of claim 1, wherein the packaging container has a bottom, at least two side walls, and an open end, and wherein the packaging material has edges.
- 16. The packaging container of claim 1, wherein the packaging container is formed by folding the packaging material and applying heat to the edges of the packaging material.
- 17. The packaging container of claim 1, wherein the packaging material is rectangular in shape.
- 18. The packaging container of claim 1, wherein a closure is attached to the packaging container, and wherein the closure is selected from the group consisting of rail fastener, rail fastener with slider, press to close, zipper, and hook and loop.
- 19. The packaging container of claim 1, wherein the packaging container has one or more gussets in the bottom of the packaging container.
- 20. The packaging container of claim 19, wherein the textile layer of woven polyester fabric has been removed from the gussets.
- 21. The packaging container of claim 1, wherein the packaging material is sufficiently stiff to allow the packaging container to be self-supporting.
- 22. A packaging container formed of a packaging material comprising:
a textile layer of woven polyester fabric; and a thermoplastic layer of metallocene catalyzed low density polyethylene.
- 23. A packaging container formed of a packaging material comprising:
a textile layer of woven polyester fabric, wherein the woven polyester fabric is comprised of warp and fill yarns, wherein the warp yarns are comprised of 1/150/48 or 1/150/50 denier textured polyester yarn, and wherein the fill yarns are comprised of 1/150/48 or 1/150/50 denier textured polyester yarn; and a thermoplastic layer of polyolefin.
- 24. A packaging container formed of a packaging material comprising:
a textile layer of woven polyester fabric, wherein the woven polyester fabric is comprised of warp and fill yarns, wherein the warp yarns are comprised of 1/150/48 or 1/150/50 denier textured polyester yarn, and wherein the fill yarns are comprised of 1/150/48 or 1/150/50 denier textured polyester yarn; and a thermoplastic layer of metallocene catalyzed low density polyethylene.
