The invention concerns five-layer tubular polyamide film for wrapping and covering paste-form foodstuffs, in particular for use as sausage skins, the film being characterized in that it is made up of an inner and an outer laye r made of the same polyamide material consisting of at least one aliphatic polyamide and/or at least one aliphatic copolyamide and/or at least one part ly aromatic polyamide and/or at least one partly aromatic copolyamide, a middle polyolefin layer and two bonding-agent layers each made of the same material . The proportion of partly aromatic polyamide and/or copolyamide is 5 to 60 %, in particular 10 to 50 %, relative to the total weight of the polymer mixtur e of partly aromatic and aliphatic polyamides and copolyamides. |
