Patent ID: 7498373

Claim:
A hot-sealable coating system suitable for the sealing of various types of substrate and composed of a film-forming dispersion made from at least two different polymer types A and B, and of an organic solvent system L, comprising: a polymer type A which is an olefin polymer or an olefin copolymer, a polymer type B which is a (meth)acrylate copolymer, containing standard (meth)acrylates and a total of up to 15% of methacrylic acid and/or acrylic acid, and/or another polymerizable acid, and the ratio A:B by weight of the two polymer types present ranges from 0.4:1 to 2:1, and the dispersion comprises a polymer containing components which correspond to the two polymer types A and B; and wherein the organic solvent system L consists of a mixture of 40-70% by volume of propyl acetate, 24-45% by volume of ethyl acetate, and 5 to 15% by volume of isooctane.
