MULTIPLE LAYER FILM CAPABLE OF A LINEAR TEAR PROPAGATION

摘要

A multilayer film is provided, including a layer sequence of a layer (a) of at least one low density polyethylene (LDPE) having a density in the range 0.915-0.930 g/cm3 or a mixture of LDPE with at least one other acyclic C2-C6 olefin polymer or copolymer, a layer (b) of a mixture of at least one low density polyethylene (LDPE) having a density in the range 0.915-0.930 g/cm3 and at least one cyclic olefin copolymer, and a layer (c) of at least one low density polyethylene having a density in the range 0.915-0.930 g/cm3 or a mixture of LDPE with at least one other acyclic C2-C6 olefin polymer or copolymer, such that the film's tear propagation force in both the machine direction and transverse to the machine direction is at most 1000 mN, per the Elmendorf test (per DIN EN ISO 6383-2).
