Curl-free polyolefin-based film used for the packaging of sterile products

摘要

The present invention relates to a multilayer, substantially curl-free, coextruded polymeric film for the production of packaging for medical devices intended to be terminally sterilised by heat, gamma or beta irradiation, comprising:
- a polyolefinic base layer comprising between 10 % and 50 % by weight of a cyclic olefin copolymer having a Tg higher than 130°C;
- a polyolefinic sealing layer having a thickness between 5 and 15 % of the total film thickness.
