Multilayered co-extruded high-temperature boiling-resistant high barrier film

[0022] Such as figure 1 As shown, a multi-layer co-extruded high-temperature cooking high-barrier film. The barrier film includes an inner layer 1, a barrier layer 2 and an outer layer 3. The inner layer 1 includes PA layer 11 and PP layer 12, PA layer 11 and The PP layer 12 is rolled through the adhesive layer 41 to obtain the inner layer 1. The PA layer 11 in the inner layer 1 is composed of the following components by weight: 50 parts of silicone resin, 10 parts of aluminum hydroxide, and carbonic acid 5 parts of potassium, 1 part of XC-99-B5654 silicone flame retardant, 0.3 parts of polycaprolactam, PP layer 12 is composed of the following components by weight: 100 parts of chlorinated modified polypropylene, 15 parts of silicone grease, 10 parts of silane, the preparation method of the inner layer 1 is: send the silicone resin and aluminum hydroxide to a ball mill for pulverization, smash through a 400-mesh sieve, send to a mixer, add water and stir for 15 minutes, then add po
