Abstract:
1. A method of producing a textured, layered mold-formed body with a foil laminate, wherein the method comprises: providing a top foil comprising at least one polymer material in a no more than partially crosslinked state; providing at least one sub-foil comprising a polymer foam material in a no more than partially crosslinked state; laminating the at least one sub-foil onto the top foil and thereby producing said foil laminate and simultaneously embossing the top foil and thereby providing a foil laminate with the texture; treating the textured foil laminate with an electron beam to promote crosslinking and wherein said crosslinking treatment is performed with a radiation dose of substantially 20 KGy to 150 KGy to provid a requisite stability to said texture for a subsequent deep-drawing step and to achieve in the top foil material a gel content of 20 to 70% and in the sub-foil material a gel content of 30 to 70% and a density between 35 grams per liter and 120 grams per liter; and deep-drawing the radiated foil laminate and thereby producing said textured, layered mold-formed body.
