Abstract
Official abstract text for this publication.
The present invention relates to an oil and water absorbent food packing material, a method for manufacturing the same, and a tray using the same, and more particularly, to an oil and water absorbent food packing material that is obtained by bonding a porous layer and a substrate layer through extrusion lamination, to a method for manufacturing a porous food packing material by means of extrusion lamination of a porous layer and a substrate layer, and to a tray manufactured by molding the food packing material so that it can absorb oil and water generated from a frozen food to be cookable in a microwave oven.
First claim
Opening claim text (preview).
What is claimed is: 1 . An oil and water absorbent food packing material comprising: a porous layer; and a substrate layer disposed on the underside of the porous layer. 2 . The oil and water absorbent food packing material according to claim 1 , wherein the porous layer is any one selected from a porous film and a fabric. 3 . The oil and water absorbent food packing material according to claim 1 , wherein the porous layer is made of any one selected from polyester and polyolefin. 4 . The oil and water absorbent food packing material according to claim 1 , wherein the pores formed on the porous layer have sizes in the range of 2 to 10 μm. 5 . The oil and water absorbent food packing material according to claim 1 , wherein the substrate layer is made of any one selected from polyester and polyolefin. 6 . The oil and water absorbent food packing material according to claim 1 , wherein the substrate layer is made of the same material as the porous layer. 7 . A method for manufacturing an oil and water absorbent food packing material, the method comprising the step of bonding a porous layer and a substrate layer to each other by means of extrusion lamination. 8 . The method according to claim 7 , wherein the pores of the porous layer are formed by means of laser processing, pinpoint processing or chemical treatment. 9 . An oil and water absorbent tray manufactured by molding the oil and water absorbent food packing material according to claim 1 .
