The production of conventional PVC shrinkable film has lower thresholds for glass transition temperature and equipment requirements. The unique shrinkability and flexible processing options also make replacing PVC outright very difficult. However, environmental awareness is on the rise. In light of the harmful environmental and health effects caused by PVC, the international community is tightening restrictions on the use of this material for packaging.

By capitalizing on its research on differences in material qualities, the vertically integrated industry chain as well as the repolymerization and shrinkable film production technologies, FENC has created such replacement – PET shrinkable film. The Company overcame several obstacles during production. It is challenging to cool and transport high-temperature plastic materials and to maintain a consistent process during which melted high-temperature PET materials must be cooled and stabilized to be pressed and extended into shrinkable films. The PET shrinkable film is highly shrinkable under low temperatures with good aging resistance, making it an ideal substitute for PVC shrinkable film. The product has been certified by the Association of Plastic Recyclers, and sales and revenues from this product grew exponentially in 2022. A larger market share means that more PVC films will be replaced and that FENC is making significant contribution to environmental sustainability.
