(FR) STRUCTURE COMPOSITE POUR CONTAINERS ET AUTRES.
Abstract
(EN) A composite layered structure for use in making containers for storing edible food products which comprise a paper board coated on one surface thereof with a polycoat selected from the group consisting of polyolefins, copolymers containing a polyolefin as one of the constituents thereof, polyvinyl chloride and polyvinylidene chloride, and a wax layer provided on both surfaces of the polycoated paper board to form said wax-paper-polycoat-wax composite structure.
(FR) Une structure à couche composite est utilisée dans la fabrication de containers pour le stockage de produits alimentaires commestibles et consiste en du papier cartonné revêtu sur l'une de ses surfaces d'un revêtement à couches multiples parmi le groupe constitué de polyoléfines, de copolymères contenant une polyoléfine comme l'un de leurs constituants, du chlorure de polyvinyle et du chlorure de polyvinylydène, et les deux surfaces du papier cartonné ainsi revêtu sont enduites d'une couche de cire pour former cette structure composite cire-papier-revêtement à couches multiples-cire.
