Modified polyolefin films

摘要

Disclosed are techniques and related material blends for improving adhesion between a polyolefin film and a pressure sensitive adhesive, and also significantly decreasing the coefficient of thermal expansion of a polyolefin film by modifying the chemical properties of the film. Specifically, particular amounts of a modifying polymer and/or copolymer such as ethylene vinyl acetate are incorporated into the polyolefin film. The polyolefin film may for instance be either a polyethylene or polypropylene film.
