摘要:
Process for the production of an oriented plastic film from polyolefins and/or combinations of polyolefins and polyamide that are manufactured by the extrusion and/or coextrusion blowing process, where initial biaxial orientation is carried out during the blowing process and this is followed by another orientation operation.
摘要:
Process for the production of a multilayer composite material with a plastic layer that has release properties with respect to adhesives, where the materials producing the release properties are located within the plastic layer, where a first web is provided in production of the composite materia on the one side of which a layer of adhesive is located, after which the plastic layer with the release properties follows, which is in turn bonded to a second web.
摘要:
The invention relates to a method for producing thin layers (3) of a silicon that can be subjected to plastic treatment, whereby the silicon layer (3) is extruded, and to the thin silicon layer produced by said method.
