In a process for the welding of plastic films lying flat, one on top of the other, the plastic films are brought into contact with a heated cutting edge and hot-tool welded. Two-layered or multilayered composite films of different chemical composition are used for the welding; for example, one composite film can be an opaque, colored or uncolored layer, on which there is arranged a transparent sealing layer comprised of a propylene-ethylene copolymer or a propylene-ethylene blend. The sealing layer of the opaque composite film is welded directly to a sealing layer of a second, transparent composite film.

A multi-layer laminate web for furniture formed of a polyolefin web containing a mixture or blend of specific proportions by weight of a propylene homopolymer or copolymer and specific proportions by weight of a low pressure polyethylene, polyvinylalcohol, ethylene-vinylalcohol copolymer, ethylene-acrylic acid copolymer, ethylene-acrylate ester-acrylic acid copolymer or -terpolymer and/or polycaprolactone or a mixture of blend of low pressure polyethylene with one or more of the foregoing polymers, copolymers or terpolymers and specific proportions by weight of a finely divided mineral filler or mineral filler mixture having on the surface thereof a substance having polar and non-polar groups, and a surface layer having an average thickness from 3 to 30 microns applied over the polyolefin web. A method for producing a furniture laminate is also disclosed.
