| description | The present invention relates to a biodegradable laminating film having the layer structure A/B, wherein the 0.5 to 7 µm thick layer A comprises a polyurethane adhesive or acrylate adhesive; and wherein the 5 to 150 µm thick layer B comprises an aliphatic polyester and/or aliphatic-aromatic polyester, wherein the aliphatic-aromatic polyester is composed as follows: b1-i) 30 to 70 mol %, based on components b1-i and b1-ii, of a C6-C18- dicarboxylic acid; b1-ii) 30 to 70 mol %, based on components b1-i and b1-ii, of terephthalic acid; b1-iii) 98 to 100 mol %, based on components b1-i and b1-ii, of 1,3-propanediol or 1,4-butanediol; b1-iv) 0 to 2 wt.%, based on the components b1-i and b1-iii, of a chain extender and/or branching agent.
La présente invention concerne un film de stratification biodégradable ayant la structure de couches A/B, la couche A épaisse de 0,5 à 7 µm comprenant un adhésif de polyuréthane ou un adhésif d'acrylate ; et la couche B épaisse de 5 à 150 µm comprenant un polyester aliphatique et/ou un polyester aliphatique-aromatique, le polyester aliphatique-aromatique étant composé de la manière suivante : b1-i) 30 à 70 % en mole, sur la base des composants b1-i et B1-ii, d'un acide en C6-C18-dicarboxylique ; b1-ii) 30 à 70 % en mole, sur la base des composants b1-i et b1-ii, d'acide téréphtalique ; b1-iii) 98 à 100 % en mole, sur la base des composants b1-i et b1-ii, de 1,3-propanediol ou de 1,4-butanediol ; b1-iv) 0 à 2 % en poids, sur la base des composants b1-i et b1-iii, d'un allongeur de chaîne et/ou d'un agent de ramification. |
