| 摘要 | Multilayer polyolefin film comprising a layer sequence of a sealable layer (a) based on a polyethylene component, a layer (b) based on a polymer mixture of 51-85 wt. % of at least one polyethylene and 15-49 wt. % of at least one propylene homopolymer or copolymer and a sealable layer (c) based on a polyethylene component, wherein the melting point of the layer (a) or the layer (c) is at least 5° C. lower than the melting point of the layer (b); the tear propagation capability of the polyolefin film in the machine direction is 15 N approximately equal manner in machine direction as well as transversally to the machine direction. | ||||||
