GAS TIGHT POLYPROPYLENE PEEL FILM

摘要

The present invention is related to a coextruded multilayer polyolefin film being heat sealable and peelable onto polypropylene based substrates of at least 3 layers, comprising at least a peelable top layer, at least an intermediary layer and at least a base layer, characterised in that at least one of the intermediate layers comprises an easy flowable low melting polymer with a melt flow index at least equal or higher than the melt flow index of the base layer.
