<p>Producing a paper or foam composite including paper (A), adhesive layer (B) and foam layer (C), comprises (a) presenting a paper (A), (b) applying a thin adhesive layer (B) on the paper or to the foam layer (C), and (c) pressing foam layer with a thickness of 1-200 mm on the paper side, where the foam layer (C) comprises polylactic acid, at least one polyester based on aliphatic and/or aromatic dicarboxylic acids and aliphatic dihydroxy compound, an epoxy group-containing copolymer based on styrene, acrylic acid esters and/or methacrylic esters and at least one additive. Producing a paper or foam composite including paper (A), adhesive layer (B) and foam layer (C), comprises (a) presenting a paper (A) with a surface weight of 30-600 g/m 2>, (b) applying a thin adhesive layer (B) on the paper or to the foam layer (C), and (c) pressing foam layer with a thickness of 1-200 mm on the paper side, where the foam layer (C) comprises: (in wt.%) (i) polylactic acid (50-98.9, based on the total weight of components (i) to (iii)); (ii) at least one polyester based on aliphatic and/or aromatic dicarboxylic acids and aliphatic dihydroxy compound (1-49.9,based on the total weight of components (i) to (iii)); (iii) an epoxy group-containing copolymer based on styrene, acrylic acid esters and/or methacrylic esters (0.1-2, based on the total weight of components (i) to (iii); and (iv) at least one additive (0-10, based on the total weight of components (i) to (iv)). An independent claim is also included for producing of a paper or foam composite including A,B,C,B,A respectively, comprising presenting the paper (A) with the surface weight of 10-300 g/m 2>in each case, applying respective the thin adhesive layer on the paper or to the foam layer, bringing the foam layer with the thickness of 1-200 mm between the two paper sides, and pressing to form the composite including A,B,C,B,A respectively.</p> |
