Polyethylene toughened high-temperature cooking film with high barrier function as well as production process and application of polyethylene toughened high-temperature cooking film

The polyethylene toughened high-temperature cooking film with the high barrier function sequentially comprises a composite layer, a first barrier layer, a reinforced supporting layer, a second barrier layer and a heat sealing layer from top to bottom, raw materials of the composite layer, the first barrier layer and the second barrier layer are PE blends, raw materials of the reinforced supporting layer are blends of SEBS and PE, and raw materials of the heat sealing layer are PE blends. And the raw material of the heat sealing layer is a blend of PE and PP. The film prepared according to the formula can resist boiling at the high temperature of 121-125 DEG C for 40 minutes, can resist storage at the low temperature of-18 DEG C, also has high toughness, can resist falling at the normal temperature of 3-4 m, has high barrier property, excellent solvent permeability resistance and heat sealing property, is self-sealed, and can be well heat-sealed with PP (polypropylene) and PE (polyethylene). 本发明一种具高阻隔功能的聚乙烯增韧高
