'Plastic film for use in the manufacture of multilayer packaging in the form of a bag for packaging milk and milk drinks

摘要

Plastic film of complex structure for use in the manufacture of packaging, where the film (f) is obtained by CO extrusion process of tubular films, and with the combination, in its structure, the PA (polyamide) with the thickness ranging from 5 microns to 50 microns; (b) adhesives - the standard Lmente based LDPE (low-density polyethylene).With the thickness ranging from 2 microns to 10 microns; (c) PP (polypropylene) for application in the innermost layer of the packaging and with a thickness ranging from 5 microns to 50 microns; and D) EVOH (ethylene vinyl alcohol copolymer) which acts as a barrier to oxygen and operates in a complementary way Ba The oxygen rreira offered by polyamide.This layer of EVOH having a thickness ranging from 2 micron to 20 microns; the film (f) has a structure that comprises five layers of material.
