Abstract (en)
[origin: CA2656476A1] The invention relates to a multilayer film comprising a layer A which is based on a thermoplastic polymer or a mixture of several thermoplastic polym ers having a melting point Tm A and a Vicat softening point TV A and has a m aximum layer thickness of 40 .mu.m, and a layer B that directly adjoins laye r A, is based on a thermoplastic polymer or a mixture of several thermoplast ic polymers having a melting point Tm B and a Vicat softening point TV B, an d has a maximum layer thickness of 50 .mu.m, wherein TV B < TV A and Tm B < Tm A; TV B <= 115°C. The inventive multilayer film comprises at lea st one at least monoaxially oriented layer while comprising an external seal ing layer. An area D that is printed and/or metallized and/or coated with a (semi)metal oxide is arranged between layer A and layer B. The minimum inter layer adhesion between layer A and layer B amounts to 1.0 N/15 mm.
