The invention relates to a method for laminating a plastic film with a wood-base substrate, in particular for producing a high-gloss surface on a wood-base substrate, in which a plastic film is laminated by means of a laminating agent, preferably an adhesive, with a wood-base substrate and permanently bonded to the wood-base substrate, the plastic film being formed so as to be transparent on its top, and the products obtainable in this manner and their use, in particular in the area of the wood and furniture industry, for example for the production of pieces of furniture and fitments of all kinds.

1. A method for producing a wood-base substrate provided with a high-gloss surface by laminating a plastic film with a wood-base substrate, the method comprising laminating a plastic film with a wood-base substrate by applying a laminating agent there between and applying pressure and heat, thereby permanently bonding the plastic film to the wood-base substrate, the treatment of the plastic film with the laminating agent being effected over the whole area of the plastic film and homogeneously with uniform layer thickness in the range of from 1 to 1,000 μm, wherein the plastic film is formed so as to be transparent on its top, has a thickness of 0.005 to 15 mm and has, on its top, a gloss value, as determined according to DIN 67530 at an angle of measurement of 60°, in the range of from 100 to 200, and wherein the plastic film is an oriented plastic film and wherein the tensile strength of the plastic film in the longitudinal and transverse direction is at least 100 N/mm2 and wherein the modulus of elasticity of the plastic film in the longitudinal and transverse direction is at least 3,000 N/mm2 and wherein the elongation at break of the plastic film in the longitudinal and transverse direction is at least 90% and wherein the laminating agent is a transparent or colorless, extrudable or film-forming, solvent-free hot-melt adhesive, such that a wood-base substrate provided with a high-gloss surface is obtained, wherein a decorative layer is additionally arranged between the plastic film and the wood-base substrate, and wherein the lamination of the plastic film with the wood-base substrate is followed by a heat treatment subjecting the laminated material on its surface laminated with the plastic film to a temperature in the range of 50-100 degrees C. within 15 minutes after the lamination process. 2. The method according to claim 1, wherein the plastic film is first treated with the laminating agent and then the plastic film and the wood-base substrate are united in such a way that the plastic film is permanently bonded to the wood-base substrate and that the plastic film is laminated with the wood-base substrate. 3. The method according to claim 1, wherein the joining of plastic film and wood-base substrate is effected with heating above the melting or softening range of the laminating agent. 4. The method according to claim 1, wherein the plastic film used is a single-layer or multilayer plastic film. 5. The method according to claim 1, wherein the plastic film used is a plastic film based on polyolefins, polyesters, poly(meth)acrylates, polystyrenes or acetates. 6. The method according to claim 1, wherein the laminating agent is applied in an amount of from 0.1 to 200 g/m2 and wherein the laminating agent is applied with heating at temperatures in the range of from 80 to 200° C. 7. The method according to claim 1, wherein the laminating agent used is a hotmelt adhesive selected from the group consisting of thermoplastic and reactive hotmelt adhesives. 8. The method according to claim 1, wherein the laminating agent used is a thermoplastic hotmelt adhesive based on ethylene/vinyl acetates, polyolefins, polyacrylates, copolyamides, copolyesters or polyurethanes. 9. The method according to claim 1, wherein the laminating agent used is a moisture-crosslinking or radiation-crosslinking hotmelt adhesive. 10. The method according to claim 1, wherein the lamination of the plastic film with the wood-base substrate is followed by finishing, the finishing comprising fabrication and size change. 11. Laminated material having a plastic film laminated with a wood-base substrate as obtained by the method of claim 1. 12. Furniture comprising a laminated material as obtained by the method of claim 1.
