  • Paper-like white-opaque heat-sealable polypropylene film
    Patent number: 5466520
    Abstract: The invention relates to a white-opaque biaxially orientated multilayer film with good heat-sealing properties and with a paper-like appearance on at least one side, comprising an opaque core and at least one outer layer made of:10-15% by weight of an isotactic polypropylene having a density of 0.9-0.91 g/cm.sup.3 and a melt-flow index of 0.5 g/10 min to 8 g/10 min at 230.degree. C. under 21.2 N load (determined to DIN 53735),5-15% by weight of a low-density linear copolymer of ethylene, modified with rubber and with maleic acid anhydrite,40-80% by weight of a statistical propylene/ethylene copolymer with 2 to 6% by weight of ethylene or statistical terpolymers of propylene, ethylene and butylene with a comonomer content of <15% by weight and a butylene content of <7% by weight and5-15% by weight of an inorganic filler, preferably rutile-type titanium dioxide with an average diameter of 200 nm.

  • Multilayer, stretched heat-sealable polypropylene film combining good surface slip with improved barrier properties
    Patent number: 5447792
    Abstract: The invention relates to oriented, sealable polypropylene film combining an improved water vapor barrier effect with a considerably reduced coefficient of friction for packaging purposes, characterized in that they are free from polydimethyl siloxane and have the following structure:A B C B Awherea) C is the core layer consisting of polypropylene and a hydrocarbon resin, which has a molecular weight of up to about 2000 g/mol and a softening point above 130.degree. C., and 0.05 to 0.5% by weight erucic acid amide,b) the B's are two jacket layers of highly isotactic polypropylene (isotacticity >94%) free from hydrocarbon resin, the ratio between the thickness of the jacket layer and the thickness of the base layer being between 0.01 and 0.1,c) the A's are two surface layers of a heat-sealable polyolefin copolymer or terpolymer, these surface layers containing at least one antiblocking agent, an antistatic agent and, as lubricant, 0.05 to 0.5% by weight erucic acid amide.
