Abstract

A textured, layered mold-formed body is produced with a foil laminate in which a top foil of at most partially crosslinked polymer materials and a sub-foil containing a polymer foam material with a density between 35 and 120 grams per liter and a gel content of less than 80 percent are laminated together. The foil laminate is embossed with a texture and treated with electron beams to give the texture enough stability for a subsequent deep-drawing step in which the mold-formed body is produced.
