摘要:
The present invention relates to polypropylene film-adhesion promoter-metal laminates, adhesion promoter used being polypropylene modified with carboxyl groups and/or anhydride groups. Polypropylene random copolymers of 90 to 99% by weight, preferably 93 to 99% by weight, of propylene and 1 to 10% by weight, preferably 1 to 7% by weight, of comonomers, having a molecular weight distribution M.sub.w :M.sub.n in the range from 2 to 10, preferably 3 to 6, and a melt flow index MFI 230.degree. C./2.16 kg in the range of 1 to 20 g/10 min, preferably in the range from 4 to 15 g/10 min, are used for the production of the polypropylene film.
摘要:
A laminate comprising a substrate, a thermoplastic film, a paper layer, and a surface-finishing coating is described. The thermoplastic film is a coextruded, three-layer plastic film. The outer layers of the plastic film contain one or more polyolefins having a carboxyl group content of 0.05 to 30% by weight, and the inner layer of the plastic film contains polyethylene, polypropylene, and polyethylene copolymer, or a polypropylene copolymer. The laminates may be produced in one or more process steps and are useful for the manufacture of furniture and boards.
