MULTILAYER METALLISED FILM

摘要

The invention relates to a metallised film, produced by means of a multilayer structure with a binder layer comprising 5 to 50 wt. % of a mixture (A) with: 5 to 100 % of a mixture of co-grafted polymers (C1) and (C2) comprising 90 to 20 wt. % of a polyethylene metallocene (C1) with a density of between 0.865 and 0.915, 10 to 80 wt. % of a polymer (C2) which is either a non-metallocene LLDPE or a homo- or co-polymerised polypropylene and 95 to 0 wt. % of a polyethylene (D) selected from the homo- or co-polymerised polyethylenes and the elastomers. The mixture (A) is such that the content of graft monomer grafted is between 30 and 10<5> ppm, the MFI or flow index in the molten state (standard ASTM D 1238, at 190 DEG C with 2.16kg) is between 0.1 and 30g/10min and 50 to 95 wt. % of a polypropylene (B) homo- or co-polymer.
