Document Type and Number:
Japanese Patent JP2005535481
Kind Code:
A
Abstract:
The invention relates to a multilayer polyolefin film composed of at least three layers, comprising a) a core layer A functioning as base layer and composed of at least one amorphous polyolefin or of a mixture of at least one semicrystalline polyolefin and 5.0% by weight or more of at least one amorphous polyolefin and b) on the two sides, outer layers B and C, which are identical or different, composed of a polyolefin (polyethylene, polypropylene) and/or a mixture composed of polypropylene and of an amorphous polyolefin. The films of the invention have very good thermoformability together with low shrinkage. The chemical structure of the core layer A gives exceptionally low water absorption and superior barrier action with respect to water vapor. The invention further relates to the use of this film and to a process for its production.
