Multilayer film with high tear propagation resistance and low shrinkage
Multilayer film with high tear propagation resistance of at least 300 mN for a total layer thickness of 45 μm, a shrinkage of ≤1% at 120° C. and release properties, comprising a layer (a) formed of at least one propylene copolymer and optionally at least one olefin homopolymer, at least one internal layer (b) formed of at least one olefin/alkyl (meth)acrylate copolymer, a layer (c) formed of at least one propylene copolymer and optionally at least one olefin homopolymer with optional adhesion layers (d) and (e) arranged between layers (a) and (b), and between layers (b) and (c) respectively.
