Abstract: The invention relates to a barrier foil, wherein a barrier composite (5) consisting of two carrier foils (3), each of which contains an inorganic barrier (4) (SiOx or AlOx), is combined by lamination or extrusion coating with a weather-resistant protective layer (1), wherein a bonding agent is used as an adhesive layer (2).

Abstract: The invention relates to a barrier film, in which a backing film (4) containing an inorganic barrier (3) (SiOx or AlOx) is combined with a weather-resistant protective layer (1) using lamination or extrusion coating, an adhesion promoter being used as the adhesive layer (2).

Abstract: A process for producing packaging composed of thermoformable film composed of thermoplastic polyolefins provides the thermoforming of the film at temperatures in the range from 70 to 170° C., thus giving packaging which has a high heat distortion temperature in the range from 60 to 200° C. and which has a high water-vapor barrier. The thermoformable film comprises an amount in the range from 5 to 100% by weight of COC with a glass transition temperature Tg in the range from 65 to 200° C.

Abstract: The present invention relates to a thermoformable composite film, a process for producing a thermoformable composite film, the use of a solvent-free adhesive for applying a thermoplastic film to a film comprising cycloolefin copolymer in order to produce a thermoformable composite film, an extrusion coated film and a process for producing an extrusion coated film and use of the film as a packaging material.

Abstract: The present invention relates to a mono- or multilayer film, where the film consists of a cycloolefin copolymer or mixtures of cycloolefin copolymers and one or more thermoplastics, and where, at 85% relative humidity and a temperature of about 23° C., the film has a water vapor permeation of ≦0.035 g*mm/m2d, a puncture resistance of ≦300 N/mm and a thickness of ≦100 &mgr;m.

Abstract: The present invention relates to a thermoformable composite film comprising at least one film which comprises cycloolefin copolymer and comprising, laminated to at least one side of this film, a thermoplastic film. The thermoformable film is obtainable by using a solvent-free single-component adhesive to apply the thermoplastic film laminated to the film which comprises cycloolefin copolymer. The film which is laminated is a PVDC-containing thermoplastic film. The thickness of the entire film is from 100 to 500 &mgr;m, the thickness of PVDC film is from 5 to 150 &mgr;m and the thickness of the COC film is from 50 to 400 &mgr;m. The thermoformable composite film is used to produce blister packs.

Abstract: A coating agent for plastic films which contains an intrinsically electrically conducting polymer and one or more additives which have an anti-adhesion action with respect to a metal coating to be applied to the plastic film can be used to coat plastic films. The plastic films so coated can be used to transfer a coated metal to another substrate.

Abstract: A process for producing an article by transferring to at least one surface of the article, a surface structure of a polymeric film, the surface structure comprising individual, randomly distributed elevations, so that the resultant article comprises the surface structure or a mirror image of the surface structure, the transferring comprising: a) applying the film to the article as a cover layer wherein a surface of the film comprising the structure faces outward from the article; or b) transferring the surface structure of the film to the article by applying a surface of the film having the structure to the article, so as to form a mirror-image of the structure on the molded body, and optionally removing the film; the process produces an article having at least one surface which exhibits antireflection properties.

Abstract: A thermoformed plastic package with integrated predetermined breaking points formed by discrete regions in the plastic matrix at which points the mechanical properties of the plastic have been modified by action of a laser beam.

Abstract: A cup-like package of plastic for substantially flowable or pourable products is described. It includes a one-piece receptacle, the top filling and removal opening of which is sealed by a peel-off cover film. The cover film, which is of plastic, has a surface texturing.

Abstract: A laminated material having a latent inherent delamination potential which contains at least one layer comprising a thermoplastic, wherein the thermoplastic carries, at least on one side, a release layer of water-soluble or water-dispersible organic material. The material can be delaminated by a process of chopping the material and treating the material with water or steam. The laminated material is useful as, for example, a packaging material. The material can easily be delaminated into its individual layers, thus facilitating recycling of the materials.

Abstract: A self-adhesive bituminous sealing web having a support layer in the form of a scrim, a woven fabric or a non-woven material, both surfaces of which are covered with a bituminous coating, an adhesive layer disposed on one surface thereof and a cover sheet. The cover sheet includes at least one thermoplastic polymer layer and at least one layer of a woven fabric or non-woven material made of highly tear-resistant plastic fibers or threads.

Abstract: Disclosed is a filtration process for separating solid, sludge-like and dissolved constituents from effluent, comprising the steps of introducing under an elevated pressure the effluent into a tube-shaped filter having a closed end and an open end, the tube-shaped filter being comprised of a semi-permeable material, the point of introduction of the effluent being initially near the closed end of the filter; moving the point of introduction of the effluent away from the closed end and toward the open end of the filter; and adjusting the rate of introduction of the effluent into the filter to achieve a predetermined content of solids in the concentrate remaining inside the filter. Also disclosed is a device for carrying out this process.
