Date Sep. 25, 1997A multilayered film having a polymer outer layer, a polymer connecting layer and a heat-sealable polymer inner layer. At least one polymer connecting layer being made of a mixture of a polypropylene homopolymer and/or a polypropylene copolymer and at least one thermoplastic elastomer and/or a mixture of a polypropylene homopolymer and/or a polypropylene copolymer and polyisobutylene. The heat-sealable polymer inner layer, which is adjacent to the connecting layer, is made of a polypropylene homopolymer and/or a polypropylene copolymer with at least one thermoplastic elastomer; excluding polypropylene homopolymers and/or polypropylene copolymers made up predominantly of polyethylene. The multilayered film is used for making packaging materials to package foods, medical fluids or solutions, such as saline solutions, amino acid solutions, dialysis solutions, blood or blood substitute solutions.</p> |
