    摘要: The invention relates to a polymer-coated heat-sealable packaging material, its manufacturing method and a sealed package manufactured thereof. The material comprises a fibre base (3), which is a packaging paper or packaging board, an outer polymeric heat sealing layer (1, 8), which is, for example, LDPE, and an inner polymeric water vapour barrier layer (2, 7), which according to the invention is partly or totally formed of cycloolefin copolymer (COC). The COC water vapour barrier and the heat sealing layers are brought onto the fibre base by extrusion, and they can be placed on one side or on both sides of the fibre base for achieving a moisture barrier on both sides of the package. Also polymeric oxygen barrier layers, such as EVOH or polyamide layers can be incorporated in the packaging material. COC is amorphous, and by using it as an extruded water vapour barrier layer, curling of the packaging material is prevented. The packages according to the invention comprise carton, box and bag packages for dry and liquid foods.

    摘要: The invention relates to polymer-coated oven board and a closed oxygen impermeable food package formed from it. According to the invention, the coating on the board (1) contains an oxygen barrier layer (7) of polyamide (PA) and a surface layer (8) of polyethylene terephlatae (PET) adhered to it without a binding agent layer between them. The polymer layers (7, 8) have been produced by co-extrusion so that the polyamide layer (7) adheres directly to the board in extrusion. In a closed package according to the invention, the superimposed polyamide and PET layers (7, 8) are located inside the board layer, and on the outer surface of the package there may be a PET layer (9). The package is sealed by heat sealing the PET layers. Polyamide has been selected so that it withstands heat sealing and the heating of the package in an oven.
