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.

1 . A method of producing paper pulp mold packing of frozen foods for Oven, 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 being mixed with 10 times amount of water to form a moldable pulp, and then, the moldable pulp being applied to the paper pulp molding machine for molding, and a PET membrane being coated on the inner surface of the molded foodstuffs packing with thickness of 25 μm˜80 μm by thermosetting adhesives.  
   
   
       2 . The method according to  claim 1 , wherein said thermal resistance additives added in said natural fibers pulp is made with mixing Inorganic Aluminum Silicate with 50%˜80% parts relative to said fibrous material and Natural wax emulsion with 1.5%˜9% parts relative to said fibrous material.  
   
   
       3 . The method according to  claim 1 , wherein said cross-linking agents added in said natural fibers pulp is made with 0.75%˜5.4% parts Fluorochemical serice, 0.9%˜7.2% parts High polymer compound, 0.15%˜0.54% parts Aliphatic polyamine and 0.75%˜9% parts Alkyl acryl copolymers, relative to the amount of said fibrous material.  
   
   
       4 . A paper pulp mold packing structure of frozen foods for Oven, comprising a paper pulp mold packing with a membrane coated on the inner surface of said packing, which is charactered that said membrane is a PET membrane with thickness of 25 μm˜80 μm and being adhered to the surface of said packing by thermosetting adhesives.
