POLYOLEFIN COMPOSITIONS FOR HEAT-SEALABLE FILMS HAVING CONTROLLED PEEL STRENGTH

摘要

Polyolefin compositions for seal peel films, comprising (percent by weight): A) from 20 to 50 % of HDPE, LDPE or EVA having MFR higher than 0.3 g/10 min; B) from 30 to 80 % of a random copolymer of propylene with ethylene and/or a C4-C8 α-olefin, or of a polyolefin composition comprising not less than 20 % of said random copolymer of propylene; C) from 0 to 20 % of an elastomeric or elastomeric thermoplastic olefin polymer.
