Abstract:
A method for making a plastic film having a three-dimensionally structured and colored surface includes the steps of: providing the film with a three-dimensional surface structure via a shaping process; determining the provided topography of the film surface via a scanning process; and, applying a coloring to the surface after the topography of the surface has been determined. A device configured to apply the coloring to the surface is controlled such that the application of the coloring to the surface is changeable in dependence upon at least one of topological data of the surface and macroscopic shapes of the surface.

Abstract:
In a method for producing a thermoplastic film having a three-dimensionally textured, embossed surface, the film is subjected prior to a subsequent shaping kind of processing step to electron-beam crosslinking, which differently crosslinks the individual surface-area regions of the film, so that the regions that undergo greater degrees of drawing out during deforming have different degrees of crosslinking than their neighboring regions.
Abstract:
The invention concerns a high-frequency weldable and low-temperature flexible polymer mixture containing a copolymer of ethylene with a polar comonomer selected from the group of vinyl esters of saturated C2-C8 carboxylic acids, C1-C12 alkyl acrylates, and/or methacrylates, with the comonomer content being less than approximately 25% by weight, a terpolymer and/or copolymer of ethylene, propylene, and/or butylene, and a polar comonomer, with the comonomer content being less than approximately 25% by weight, and a thermoplastic polyolefin. The invention also provides a sheet or a molded piece containing the polymer mixture according to the invention and use thereof. Articles made with the polymer exhibit a high degree of low-temperature flexibility and favorable thermal stability together with sufficient high-frequency weldability and favorable welding seam strength.
