POLYLACTIDE FORMULATION FOR IMPROVED EXTRUSION PROCESSING

A paperboard structure includes a paperboard substrate having a first surface and an opposed second surface. A biopolymer coating is applied by extrusion or co-extrusion to at least one of the first surface and the second surface. The biopolymer coating includes an inorganic melt curtain stabilizer,...

Beschreibung
Zusammenfassung:	A paperboard structure includes a paperboard substrate having a first surface and an opposed second surface. A biopolymer coating is applied by extrusion or co-extrusion to at least one of the first surface and the second surface. The biopolymer coating includes an inorganic melt curtain stabilizer, a polylactide resin having a melt flow index, and an organic polymeric chain extender. L'invention concerne une structure de carton comprenant un substrat de carton présentant une première surface et une seconde surface opposée. Un revêtement en biopolymère est appliqué par extrusion ou coextrusion à au moins une surface parmi la première surface et la seconde surface. Le revêtement en biopolymère comprend un stabilisant inorganique de rideau en fusion, une résine polylactide présentant un indice de fluidité en fusion, et un prolongateur organique de chaîne polymérique.
