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.

摘要： Oil-soluble, phenolic resin-modified natural resinic acid esters, which are able to form self-gelling mineral oil solutions and in the form of gel varnishes can advantageously be used as binder resins in printing inks for offset printing and letterpress printing, and also processes for their preparation from natural resins, phenols, aldehydes, condensation catalyst, esterifying agents and modifiers by reaction of the components at temperatures in the range from 80.degree. to 300.degree.

摘要： A polymeric sheet structure consists of an adhesion-promoting coating on at least one surface of the substrate. The adhesion-improving coating is produced by treating this substrate surface with an electrical corona discharge between high voltage electrodes and a grounded counter-electrode while simultaneously spraying an aerosol into the corona discharge zone. The aerosol contains, for example, an aqueous emulsion of thermoplastic and/or crosslinkable components as an adhesion-promoting agent.

摘要： Moldings having a thickness of 1 to 60 mm and made of flexible webs or rigid sheet of plastic are passed through a corona discharge treatment system consisting of high-voltage electrodes and a counter-electrode and a high-frequency alternating current voltage of 20 to 25 kHz and 20 to 70 kV is applied to the high-voltage electrodes by a generator. A corona discharge forms in the gap between the high-voltage electrodes and the counter-electrode. An aerosol formed by atomizing a liquid is blown into the corona discharge zone by means of an air or gas stream. The aerosol modifies the surface of the sheet-like molding in the desired manner.
