The stretch film of PVC film is also called stretch film and heat shrinkable film. It is the first in China to use PVC as the base material and DOA as the plasticizer to produce PVC stretch film with self-adhesive effect. Due to environmental protection issues, high cost (relatively high PE proportion, less unit packaging area), poor stretchability, etc., it was gradually eliminated when domestic production of PE stretch film was started in 1994-1995.
The PE stretch film first used EVA as the self-adhesive material, but its cost was high and it had a taste. Later, PIB and VLDPE were used as self-adhesive materials. The base material is now mainly LLDPE, including C4, C6, C8 and metallocene PE (MPE).
