Multilayer structure |
摘要 |
<p>The invention relates to coextrusion binders including renewable and/or biodegradable polymers having good adhesion properties: at least one renewable and/or biodegradable polymer (A) grafted with a functional monomer including at least one reactive function, the grafting ratio being <1% in weight of the grafted polymer (A); at least one non-grafted renewable and/or biodegradable polymer (B) identical to (A) or compatible with (A) optionally a softener (C); and optionally a starch-based material (D). The invention also relates to multilayered structures including the binder of the present invention, in which the layers are preferably made of renewable and/or biodegradable compounds. The multilayered structures are advantageously useful in the field of food packaging.</p> |
