More Information
Summary:A manufacturing process of, and the relative laminated, polymeric semi-finished product are disclosed, the laminated, polymeric semi-finished product having in-depth aesthetic features, including at least two mutually welded layers by a lamination process with heat and/or pressure addition, wherein at least one of the layers is a thermoplastic material, in which the following steps are provided: providing a cohesion layer 100-500 micron thick, consisting of thermoplastic polyurethane, featuring in-depth aesthetic patterns; providing polymeric sheets with materials having a softening temperature above the one of the cohesion layer; and laminating at least one of the polymeric sheets at least partly transparent or translucent with the cohesion layer, by heat and/or pressure addition suitable to reach the softening of the cohesion layer featuring aesthetic patterns.
