FIELD: supporting structure and laminated thermo-molded film. SUBSTANCE: the film has at least one layer selected from layers (A1) and (A2). If layer (A2) is present, it joins the probably present layer (B1), probably layer (B1), layer (B2), layer (B3), probably layer (B4). Layer (A1) in the film contains fluoroplastic (A111) or polymer (A112) consisting mainly of alkylmethacrylate components, or of a mixture of both of them, layer (B2) has polyamide with terminal aminogroups in its base, layer (B3) is formed by polyolefin with functional groups obtained at action of unsaturated carbonic acid anhydride, layer (B4) consists of polyolefin. According to one of the modifications of the invention, layer (A1) consists of two layers: (A11) and (A12): • layer (A11) contains fluoroplastic (A111) or polymer (A112) consisting mainly of alkylmethacrylate components or of a mixture of both of them, • layer (A12) contains within 0 to 50 percent by mass of fluoroplastic (A111) and within 50 to 100 percent by mass of polymer (A112) consisting mainly of alkylmethacrylate components. This film is obtained by coextrusion of various layers. All the layers may extruded jointly, at least two layers may be extruded jointly and then the rest layers or separately may be applied, either with the aid of coextrusion, or any combination of the mentioned possibilities may be used. It is preferably to manufacture the film containing layers (B) and the film containing layers A, after that they should be joined at heating. The supporting structure coated by the film according to Items 1-11 may be manufactured. EFFECT: improved adhesiveness of fluoroplastic and facilitated decoration of the supporting structures of laminated films, having an outer layer of acryl or fluoroplastic polymer. 13 cl, 1 tbl
