    Abstract: A multi-layered tubular synthetic sausage casing which includes an outer polyamide layer, an inner polyolefin layer and an intermediate layer for mutually bonding the inner and outer layers. The inner polyolefin layer includes a copolymer comprised of units of ethylene, propylene or straight-chain alpha-olefins having 4 to 8 carbon atoms, or of a mixture of these copolymers. In a preferred embodiment, the polyolefin layer is comprised of an ethylene/propylene/butylene terpolymer and/or of a propylene/butylene copolymer.

    Abstract: Biaxially drawn, co-extruded, opaque film laminate comprises a polypropylene base film, coated on both sides and printable on at least one side without pretreatment by corona discharge and with an overall density of the coated film of less than or equal to 0.75 g/cc. Pref. the printable coating is a copolyester of terephthalic acid, isophthalic acid, ethylene glycol or butane diol. One side of the base film may be coated with the copolyester and the other with a heat-sealable -C2-, -C2-C3-, -C2-C4-, -C3-C4-, -C2-C3-C4- polyolefine or mixts. of these. The copolyester may be wetted with a cold sealable coat. The base film may contain 5-30, esp. 10-25 wt.% of an incompatible, (in)organic filler, specifically Ca carbonate with an ave. particle size of 0.2-8, esp. 1-5 microns. The coated films have a total thickness of 15-100, esp. 20-80 microns, a coating thickness of 0.2-3, esp. 0.5-1.5 microns and the base film density is 0.50-0.06 g/cc.
