FIELD: polymer materials. SUBSTANCE: film contains in following succession: protective layer A containing substances selected from (i) saturated polyesters such as polyethylene terephthalate, polybutylene terephthalate, copolyesters, and polyester-ethers and (ii) polyolefins homo- or copolymers; transparent layer B containing 0-100% fluorine-containing polymer B1 and 100-0% polymer B2 chiefly consisting of alkyl (meth)acrylate units; layer C based on polyamide finished in amino groups; layer D consisting of polyolefin functionalized by unsaturated carboxylic acid anhydride; and connecting polyolefin layer A. Invention also relates to polypropylene warp coated with thermoformated layered film. EFFECT: improved warp-film adhesion, reduced manufacture time, and eliminated necessity of solvent. 10 cl, 12 tbl, 11 ex |
