Paper pulp mold packing structure of frozen foods for oven and method of producing the same

Abstract

A paper pulp mold packing structure of frozen foods for Oven and method of producing the same, which is primary produced by adding thermal resistance additives containing anionic compounds with the amount equal to the natural fibers, cross-linking agents containing both nonionic compounds and cationic compounds, into pulp made from fibrous material of paper pulp, non-paper pulp and mixtures thereof, and are mixed with 10 times amount of water to form a moldable pulp. Then, the moldable pulp is applied to the paper pulp molding machine for molding, and a membrane is coated inside the molded foodstuffs packing. The membrane is a PET membrane with thickness of 25 μm˜80 μm, and is adhered to the inner surface of the molded foodstuffs packing by thermosetting adhesives. Foodstuffs packing produced by the above mentioned method can be heated with food at 220° C. in the oven about 20˜30 minutes and be stored at −35° C.
