FLEXIBLE CONTAINER AND ITS RECYCLING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a flexible container of high strength and superior durability which can resolve the environmental destruction problem at the time of being thrown away and also provide an efficient recycling method for the flexible container. SOLUTION: In the flexible container, a laminate sheet with a polyester elastomer coating on at least one face of a fabric is used as raw fabric, which is formed of polyester stretched yarns, and a main body bag 1 is formed of a raw fabric of twisted yarns formed of polyester stretched yarns. In a recycling method for the flexible container, terephthalic acid and/or its ester forming derivative is recovered by the depolymerization process of the flexible container.
