THERMOSCHRUMPFBARE POLYMERE SPERRFOLIE.

摘要

A heat-shrinkable barrier film comprised of an oriented polyolefin film coated on one side with a vinylidene chloride copolymer are disclosed. The films have excellent gas and vapor barrier properties, can surprisingly be made using conventional dispersion coating techniques, and retain acceptable optical properties even on shrinking up to as high as 35% in either transverse or machine directions or both.
