Embodiment 1

[0019] like figure 1 As shown, a high-barrier high-temperature resistant sterilization retort film is composed of a heat-sealing layer 1, a first core layer 2, a second core layer 3, and a corona layer 4. The mass percentages of the heat-sealing layer 1, the first core layer 2, the second core layer 3, and the corona layer 4 are: 20%, 30%, 30%, and 20%, respectively;

[0020] The heat-sealing layer is made of polypropylene resin (F800E) [binary copolymer resin F800E], an anti-adhesive agent and a smooth agent, and the amount of the anti-adhesive agent is 2% of the mass of the polypropylene resin. The adding amount of slipping agent is 2.5% of the quality of polypropylene resin. The anti-adhesive agent is the anti-adhesive agent AB6018PP, SiO 2 A kind of in; Described slippery agent is a kind of in the slippery agent GL5068PP of Constamp, oleamide (or oleic acid amide), erucamide, ethylene bisstearamide. Provides better coefficient of friction and heat sealing properties.

Abstract

The invention belongs to the technical field of digestion membranes. A high-barrier high-temperature-resistant sterilization digestion membrane is characterized by being formed by performing curtain coating and co-extrusion on four layers, including a heat seal layer, a fire core layer, a second core layer and a corona layer which are arranged sequentially, have the mass percentage of 20%, 30%, 30% and 20%; the heat seal layer is formed by mixing polypropylene resin, an abherent and a slipping agent. The addition amount of the abherent is 2% of the mass of the polypropylene resin; the addition amount of the slipping agent is 2.5% of the mass of the polypropylene resin; the first core layer is prepared by mixing drawing-level polypropylene resin, an elastomer, nylon and a slipping agent; the material of the second core layer is the same as the material of the first core layer. The digestion membrane prepared by the method provided by the invention has the characteristics of high temperature resistance, as well as difficulty in deformation, high heat seal intensity, strong penetration resistance, good toughness and good impact resistance under high temperature.

Description

technical field [0001] The invention belongs to the technical field of cooking films, and in particular relates to a high-barrier and high-temperature-resistant sterilization cooking film and a preparation method thereof. Background technique [0002] The existing cooking film needs to be improved in its high temperature resistance. Contents of the invention [0003] The object of the present invention is to provide a high-barrier, high-temperature-resistant sterilization retort film and a preparation method thereof. The retort film prepared by the method has the characteristics of high temperature resistance. [0004] In order to achieve the above purpose, the technical solution adopted by the present invention is: a high-barrier high-temperature resistant sterilization cooking film, which is characterized in that it is composed of a heat-sealing layer, a first core layer, a second core layer, and a corona layer. Four layers are co-extruded; the mass percentages of the h...
