Abstract:
Multilayer film (BOPP) structure comprising at least: A) a skin (outer) layer substantially consisting of a crystalline low seal Initiation temperature propylene copolymer; B) a tie layer substantially consisting of a butene-1 copolymer having flexural modulus (MEF) of 75 MPa or less; C) a core layer substantially consisting of one or more polypropylene homopolymers designed for BOPP.
