Title (EN) HEAT SEALABLE COATING WITH FILLER
(FR) REVÊTEMENT THERMOSCELLABLE AVEC CHARGE
Abstract:
(EN) A coating for paperboard includes polyethylene outer layers and a polyethylene inner layer with calcium carbonate filler. In addition to the lower cost, benefits include a surprising better heat sealing behavior compared with a coating of polyethylene alone.
(FR) L'invention concerne un revêtement pour carton comprenant une couche externe de polyéthylène et une couche interne de polyéthylène avec une charge de carbonate de calcium. Outre le faible coût, les avantages comprennent étonnamment un meilleur comportement de thermosoudage par comparaison avec un revêtement en polyéthylène seul.
