Abstract: Multilayer thermoplastic film structures are described which comprise at least two layers. One layer comprises a homopolymer polypropylene and a second layer, which is at least 3 microns thick, comprises a polyolefin material with a melting point of from 90° C. to 105° C. The film structures are particularly suited for lamination onto substrates such as paper or paper board.
