HEAT-SEALABLE POLYOLEFIN FILMS

摘要

Heat-sealable polyolefin film made of or comprising at least one layer of a polyolefin composition comprising (percent by weight): A) 20% to 80% of a heterophasic polyolefin composition comprising: A1) 3% to 30% by weight of a crystalline olefin polymer fraction; Ap) 70% to 97% by weight of an elastomeric fraction comprising at least an elastomeric copolymer of propylene or ethylene with 12 to 88% by weight of at least one a- olefin of formula H₂C=CHR, where R is H or a C2-C10 linear or branched alkyl, optionally containing 0.5 to 5% by weight of a diene, and having solubility in xylene at room temperature greater than 50% by weight; B) 20% to 80% of at least one filler.
