Abstract

Papier d'emballage pour rames en poly à un côté et à haute résistance et méthode de production de ce papier. Un copolymère et un terpolymère sont coextrudés à l'aide d'une couche de polyactide polymère (PLA). Pour ce faire, ils passent par une matrice coextrudeuse afin de forme un coextrudat. Le coextrudat est appliqué sur une couche de papier de sorte que le copolymère ou le terpolymère se trouve sur la couche de papier et la couche de PLA se trouve par-dessus la couche copolymère ou la couche terpolymère. Le copolymère ou le terpolymère peut contenir du PLA.
