On-going Solutions to Environmental Issues in Plastic Packaging

摘要

Recently, the consumption of polyvinyl chloride (PVC) and polyvinylidene chloride (PVDC) resins as packaging materials has been declining in the face of various environmental problems they pose. To replace PVC containers, the use of PET bottles and A-PET containers is on the increase, but PVDC resins are still in Wide use as gas-barrier materials. For gas-barrier purposes, however, ethylene Vinyl alcohol co-polymer (EVOH) films, polyvinyl alcohol (PVA)-coated Polypropylene films, and MX nylon or silica-or alumina-coated PET films are Becoming mainstream.
