The method for the production of thermoplastically formed arrangement of plastic films, comprises forming a film arrangement (4) having two layers by bringing together a manufactured film with a further film, extrusion coating, extrusion lamination or by coextrusion and partially providing a printing between both layers and/or on one of both layers. The film layers are connected to each other in a subsequent thermoplastic deformation. A sealing-wax is partially provided between the layers. The printing is applied before bringing together the film arrangement. The method for the production of thermoplastically formed arrangement of plastic films, comprises forming a film arrangement (4) having two layers by bringing together a manufactured film with a further film, extrusion coating, extrusion lamination or by coextrusion and partially providing a printing between both layers and/or on one of both layers. The film layers are connected to each other in a subsequent thermoplastic deformation. A sealing-wax is partially provided between the layers. The printing is applied before bringing together the film arrangement, thermoplastic deforming and/or subsequent printing after the deformation. The printing is provided for each surface side and is not completely guided. The sealing-wax is applied in a printing process, which is carried out in flexo-, sieve-, offset- or intaglio printing process. The film layers are applied to each other in adhesive contact and are tightly connected to each other during thermoplastic deformation, which is carried out as deep drawing process. The film layers are connected to each other. The thermoplastic deformation is carried out at 140-165[deg] C in a pressing pressure of 5-6 bar or at a lower pressure of 0-1 bar. The deformation time is 1.5-5 seconds and a cooling time in polypropylene is held at 0.5-1.5 seconds that is included in the deformation time. An independent claim is included for a film arrangement for the production of thermoplastically formed arrangement. |
