耐熱性ポリマー被覆オーブンボードを製造する方法、当該方法によって得られるオーブンボード、食品トレー及び食品パッケージ
Document Type and Number:
Japanese Patent JP6709170
Kind Code:
B2
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.
