Abstract: The instant invention relates to a weatherproof film comprising a substrate layer, a barrier layer and a surface layer based on polymethacrylate, wherein, according to the invention, the surface layer contains 0.1 to 15 weight % of a photocatalyst, based on the total weight of the layer, as well as to the use thereof as laminate film, tarp or the like.
Abstract: The present invention relates to an analysis device (10) for analyzing a thermoforming process in a thermoforming laminating device (20), wherein the analysis device (10) comprises a pressure housing (17) having a pressure resistance of up to 5 bar. At least one image recording device (12) that is connected to a data storage device (13) and one lighting device (11) is disposed in the pressure housing. A lens (12?) of the image recording device (12) is disposed adjacent to a light outlet opening (11) of the lighting device (11) in a housing wall of the housing (17), and the analysis device (10) comprises a temperature resistance of at least up to 50° C. The invention further relates to an analysis method for analyzing thermoforming processes in a thermoforming laminating device that can be performed by means of the analysis device (10) according to the invention.
Abstract: Process for improving the resolution of inkjet printing of polymer films comprising a base polymer according to which a copolymer additive comprising a polymer group A and a polymer group B is blended with the base polymer, group A having a lower surface tension than that of the base polymer and group B being compatible with the base polymer.

Abstract: Soft, flexible films suitable for human skin contact are required for disposable medical devices. Soft, flexible monolayer elastomer films have been developed that are suitable for human skin contact and provide improved low-temperature flexibility and improved strength to weight ratio over conventional polyvinyl chloride films for medical uses. Embodiments of the flexible monolayer elastomer film include styrene-ethylene-propylene-styrene block copolymers (SEPS), SEPS/polyolefin mixtures, SEPS/polyolefin/ethylene-vinyl acetate (EVA) copolymer mixtures, and EVA/polyolefin mixtures.

Abstract: Process for moulding sheets possessing, locally, a three-dimensional projecting or recessed structure (6), in which a blank sheet (7) is placed between the two parts of a mould, the surface of which corresponds to the negative (2) of said three-dimensional structure. At least one portion of the surface of the mould surrounding said negative possesses a feature intended to form a local reservoir able to supply or receive material of the three-dimensional structure depending on whether it is projecting or recessed, respectively.
Abstract: Use and process for manufacture of a multilayer film with a longitudinal and transverse direction, comprising: (a) a base layer; (b) a coating layer comprising a soluble polymer, pigment and/or dye, wherein the composition and/or concentration of the pigment and/or dye varies in the direction parallel to the film surface; and (c) a sealing layer.
Abstract: The present invention relates to a multilayer film for producing label material, comprising two outer layers (1, 5) of low-density polyethylene, a core layer (3) of highly crystalline polypropylene or of a blend with up to 20% of low-density polyethylene, and adhesion-promoting layers (2, 4) of polypropylene, wherein the adhesion-promoting layers contain 5-30% of ULDPE (d ≦0.9), 0-25% of LDPE and 20-95% of a random copolymer of polypropylene with a 1-alkylene having 4-20 carbon atoms, and to a process for producing such films.
