High resistant separating nature transparent film and negative and positive bag

The utility model relates to a high resistant separating nature transparent film and negative and positive bag. Separating nature of this high resistant transparent film includes extexine and heat -seal layer, is provided with high barrier layer between extexine and the heat -seal layer, and high barrier layer includes the at least one deck polyvinylidene chloride rete and at least one deck nylonrete that compounds layer upon layer in the thickness orientation. The utility model provides a separating nature of high resistant transparent film, regard as high barrier layer with polyvinylidene chloride (PVDC) rete and nylon rete complex, the PVDC rete has good moisture resistance and synthesizes barrier properties, the nylon rete has the characteristics that oxygen nature is low, excellent barrier properties and humidity resistance can be exert in both combinations, thereby it is suitable with the negative and positive bag non - transparent film's in the back barrier properties to make transparent film layer's b
