摘要： A device for smoothing out the thickness of a sheet of thermoplastic material which includes a sheet die and a heating device which is integrated with the upper die lip of the sheet die. The heating device includes a hollow box filled with a liquid and a bar which projects laterally beyond the endfaces of the hollow box. The inlet and outlet openings of the bar in the hollow box are sealed. Arranged on the underside of the bar are small hot plates which are electrically heated. The liquid in the hollow box serves as a heat transfer medium and typically is an oil having a boiling point higher than 280.degree. C. The thickness profile of the extruded sheet is controlled, on the one hand, via controlling elements and, on the other hand, remaining thick and/or thin points of the sheet profile are smoothed by the bar of the heating device, in which the bar is progressively moved transversely with respect to the running direction of the sheet across the sheet width with the aid of a motor into a position in which the small hot plates are aligned with the thick/thin points to be smoothed. The corresponding thick/thin points of the sheet are smoothed by exposing the small hot plates to different temperatures or heating powers.

摘要： A transfer-metallization method in which a metal coating is applied to a top layer of a metallizing film, and the film is then brought into contact with a substrate such that the metal coating is transferred from the top layer to the substrate. The film is a three-layer biaxially-oriented transfer film produced by coextrusion and having a base layer of a polypropylene homopolymer and top layers applied to the two surfaces thereof. The base layer contains an additive depot of migrating monomers in an amount of 0.01 to 2.0 percent by weight, relative to the weight of the polymer constituting the base layer. The top layers are comprised of polypropylene that has a lower viscosity than the polypropylene of the base layer.

摘要： A process for the preparation of a biaxially stretch-oriented film having at least one opaque layer is described. The opaque layer is composed essentially of propylene polymer and fillers in a quantity of about 10 to 40% by weight, relative to the total weight of propylene polymer and fillers. In production, the granules are melted in a screw extruder, are forced through a die and are formed by cooling to give a preformed film. The preformed film is then stretch-oriented both along the machine direction and transversely perpendicular to the machine direction and is then heat-set. The fillers are added in the form of a masterbatch to the granules of unfilled polymers. The masterbatch should have a filler content of more than about 30% by weight.

摘要： A non-sealable polypropylene multi-layer film comprises a base layer and at least one covering layer, the base layer as wella as the covering layer or layers being formed of propylene homopolymers. The covering layers contain a combination of additives composed of (a) from 0.2 to 1.0% by weight of a long-chain aliphatic amine, (b) from 0.2 to 1.0% by weight of a polydialkylsiloxane, and (c) from 0.1 to 1.0% by weight of a platelet-shaped inorganic pigment, the platelets of the pigments being disposed substantially parallel to the surface of the covering layer. The film is preferably produced by a coextrusion process. It is preferably used as a laminating film, an interleaving film or a metallizable film. The novel non-sealable polypropylene multi-layer film has, in particular, good anti-blocking and slip properties, good optical properties, good antistatic properties, and a high scratch resistance. The film can be subjected to a corona treatment without thereby adversely influencing its properties.
