A METHOD OF PRODUCING A HEAT-RESISTENT POLYMER-COATED OVEN BOARD, AN OVEN BOARD OBTAINABLE BY THE METHOD, A FOOD TRAY AND A FOOD PACKAGE |
摘要 |
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. |
