Peelable polyethylene films
摘要:
A homogenous blend comprising from 10% to 90% by weight of a metallocene catalyzed polyethylene (mPE) and from 90% to 10% by weight of styrene-butadiene block copolymers comprising from 5% to 40% by weight of 1,3 butadiene monomer units and from 60% to 95% by weight of styrene monomer unites. The blend of the invention is used to make peelable films for food packaging applications.
