Abstract
Disclosed is a layered barrier film having a first product component and a second detachable carrier component. The first product component includes a layer of material selected from a group including polyethylenes, polyethylene copolymers, polypropylene copolymers, thermoplastic polyurethanes, thermoplastic polyester elastomers, thermoplastic polyamide elastomers, thermoplastic elastomer compounds, and/or blends thereof, and a second layer made from at least partially inorganic material. The first product component has high barrier properties and is very soft. The second detachable carrier component is a layer of material selected from a group including polyethylenes, polypropylenes, polyesters, polyamides, and/or blends thereof.
Claims18
