    Abstract: The invention relates to a polymer-coated packaging material, a method of manufacturing the same, and products, such as a disposable drinking cup, made from the material. The packaging material comprises a fibrous base (1) of paper or board and an extruded polymer layer (2) containing a blend of (i) 0 to 25 wt-% of a branched low-density polyethylene (LDPE)with a lower melt viscosity and (ii) 75 to 90 wt-% of a linear low-density polyethylene (LLDPE) with a higher melt viscosity. The packaging material of the invention comprises multilayer coatings, e.g.an adhesive innermost and a heat-sealable outermost layer (2, 4) of said blend and a vapour barrier middle layer (3) of at most 90 wt- % of high density polyethylene (HDPE). The layers (2, 3, 4) are brought and adhered to the fibrous base (1) by coextrusion. To maximize renewability of the materials HDPE and LLDPE as used for the structure are of biologic origin.

    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.

    Abstract: The invention relates to a heat-sealable biodegradable packaging material, its manufacturing method and a product package formed thereof. The packaging material comprises a fibre substrate (1 ), an inner polymeric coating layer (2) against the same, which contains polylactide and a biodegradable polyester that is blended therewith to improve the adhesion between the layer and the fibre substrate, and an outer coating layer (3) that constitutes the outer surface of the material and contains polylactide and a biodegradable polyester that is blended therewith to improve the heat sealing ability of the layer, the portion of polylactide in the inner layer (2) being higher than that in the outer layer (3). The inner and/or outer coating layers (2, 3) can further have blended therewith a small amount of acrylic copolymer that improves the adhesion and/or heat sealing ability. The coating layers can be introduced onto the fibre substrate by extrusion or coextrusion.

    Abstract: The invention covers a method of producing a heat- resistant polymer-coated oven board, the resulting oven board, a food tray and a food package, which comprise such board and withstand heating in a range or microwave oven. According to the invention the coated oven board (1 ) is made by adhering a premade heat-resisting film (4) comprising polyethylene terephthalate (PET) or its derivate, such as glycol-modified PET known as PETG, to a board base (2) by extrusion lamination, in which an adhesive layer (3) comprising polyamide (PA) is extruded between the heat-resisting film and the board base. To improve the strength and barrier properties, the film (4) may be an extruded multilayer film and/or the film may be stretch-orientated to bring about crystallization in PET.
