  • Patent number: 9409697
    Abstract: A polymer-coated oven board includes a coating that contains an oxygen barrier layer of polyamide (PA) and a surface layer of polyethylene terephthalate (PET) adhered to the oxygen barrier layer. These layers are produced onto the board by co-extrusion without a binding agent layer between them. The weight of the PA oxygen barrier layer is 3-15 g/m2, and the weight of the PET surface layer is 20-50 g/m2. An oxygen impermeable food package heatable in an oven includes the oven board wherein the superimposed polyamide and PET layers are located inside the board layer in the package. The oven board may also include a PET surface layer on the opposite side of the board. Polyamide has been selected so that it withstands heat sealing and the heating of the package in an oven.

  • Publication number: 20130193026
    Abstract: 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.
