摘要： PROBLEM TO BE SOLVED: To provide a method for manufacturing multilayer mold goods, which affords a crimp consistency, does not exhibit a white breach, and can avoid damaging mechanical profiles of foam materials, above all does not cause cracking or stiffening of a foamed film, when using foam laminates. SOLUTION: The method comprises; embossing a multilayer film laminate, which is composed of an upper film using a polymeric material partially cross linked and containing an additive as needed, especially a polyolefin, as a base, and at least one lower layer; treating with electron ray to get a proper crimp consistency in a deep drawing process; and deep drawing the processed multilayer film laminate into a crimped multilayer film laminate. The method is characterized in that said at least one lower layer is formed with a foamed polymeric material with a density of about 35 to 120 g/l and a gel content of 80% or lower, preferably about 30 to 70%.

摘要： Foamed polymeric material with a density of 35-120 g/l and a gel content of less than 80 (preferably 30-70) % is used as the lower foil component of a laminate with an upper foil based on partly crosslinked polymer (especially polyolefin), which is embossed, exposed to electron beam radiation and then deep-drawn to form grained, multilayered mouldings. A method (M1) for the production of grained, multilayered moulded products (I) comprising an upper foil containing partly crosslinked polymer materials (preferably based on polyolefin) and optionally other additives and laminated with a lower foil, in which the laminate is embossed, treated with electron beam radiation (EBR) to give the graining stability required for deep drawing processes and then deep-drawn to give (I). The lower foil comprises a foamed polymeric material with a density of 35-120 g/l and a gel content of less than 80 (preferably 30-70) %. Independent claims are also included for (1) a method (M2) for the production of (I) in which the EBR-treated, grained laminate is further processed to a formed product in a single operation (not under vacuum and especially without using an adhesive system), by pressing a prefabricated, preheated support material onto the preheated back of the laminate or by bonding a plastified starting material for the support with the back of the laminate in a mould (2) supported, grained, multilayered products (I) with good grain stability and a matt surface, made by M1 or M2, in which the upper foil (as above) shows a gel content of 20-70 (preferably 25-60) wt% .
