Title (EN) POLYESTER FILM INCORPORATING SILICONE FOR RELEASE OF CANNED MEAT PRODUCTS
(FR) FILM DE POLYESTER COMPRENANT DE LA SILICONE POUR LE DÉGAGEMENT DE PRODUITS DE VIANDE EN CONSERVE
Abstract:
(EN) Butylene terephthalate-containing polyester multi-layer film, such as a biaxially oriented polyester (BOPET) film, for lamination on metal sheets, which could be used for food containers. The polyester film has an outer release layer, which aids in the release of food, such as a high protein food source, when food is cooked and sterilized in direct contact with the outer release layer. The polyester film can be laminated to metals used in the manufacture of food containers with the outer release layer being exposed to allow a direct food contact between the surface of the outer release layer and food. The outer release layer comprises an ultra high molecular weight siloxane polymer, a polyethylene terephthalate resin, an alkali-metal phosphate and a phosphoric acid.
(FR) La présente invention concerne un film multicouche contenant du téréphtalate de butylène, par exemple du polyester orienté biaxialement (BOPET), pour la stratification sur des feuilles métalliques, lequel pourrait être utilisé pour des récipients alimentaires. Le film de polyester comprend une couche antiadhésive externe, qui contribue au dégagement d'un aliment, tel qu'une source d'aliment à haute teneur en protéines, lorsque l'aliment est cuit et stérilisé en contact direct avec la couche antiadhésive externe. Le film de BOPET peut être stratifié aux métaux utilisés dans la fabrication de récipients alimentaires, la couche antiadhésive externe étant exposée pour permettre un contact direct entre la surface de la couche antiadhésive externe et l'aliment. La couche antiadhésive externe comprend un polymère de siloxane de poids moléculaire ultra élevé, une résine de téréphtalate de polyéthylène, un phosphate de métal alcalin et un acide phosphorique.
