technical field

The utility model relates to the technical field of production of reinforced stretched film, in particular to a production device of reinforced stretched film.

Background technique

Stretch film, also known as stretch film and heat shrinkable film, was the first in China to use PVC as the base material and DOA as the plasticizer and self-adhesive to produce PVC stretch film. Due to environmental protection issues, high cost and poor stretchability, etc., when From 1994 to 1995, when the domestic production of PE stretch film was started, it was gradually eliminated.
