Abstract
The flexible, reusable packaging container of the present invention is comprised of a packaging material. The packaging material is comprised of one or more layers of coating disposed on one or more layers of textile substrate. The coating layer may be comprised of a stiffening agent for providing support to the packaging container. The stiffening agent may provide a gas and/or liquid impermeable barrier between the contents of the container and the textile substrate. The stiffening agent may also include chemicals which impart antifungal or antibacterial properties to container. The textile substrate typically provides an aesthetically pleasing feel and appearance to the outside of the packaging container, as well as providing functional attributes such as water repellence, stain resistance, and/or anti-static resistance. The resulting packaging container possesses increased strength, puncture resistance, and resistance to de-lamination over the current paper or plastic packaging containers.
