【International Publication】 2005-02-17 WO2005/014283 Ying [Abstract] The present invention provides a laminated structure for beverage packaging, which has an improved barrier to the migration of major oils, aromas and aromas and has Improved oxygen barrier properties, the laminated structure comprising a polyethylene overcoat applied to the outer surface of the paperboard substrate, an Aluminum Foil, EVOH, polyamide or PET barrier applied directly or indirectly to the paperboard, an adhesive layer As well as other sub-layers that may or may not contain inorganic fillers, the tie layer and other sub-layers are applied between the barrier layer and the innermost food contact layer containing the filler. The container or carton made from the laminated structure is characterized by minimizing food loss and maintaining the quality of the food.
Sovereign Items 1. A laminate comprising: a. a paperboard substrate having opposing inner and outer surfaces, b. a heat-sealable olefin polymer coated on the outer surface of the paperboard substrate. Layer, c. a functional barrier layer applied to the inner surface of the paperboard substrate, d. a heat sealable layer of an olefin polymer comprising an inorganic particulate filler coated on the outer surface of the functional barrier layer, wherein The heat-sealable layer of the olefin polymer containing the filler constitutes the food contact layer.
