The achievement will be transformed through self investment and will be successfully transformed in 2019. In this achievement, linear low density polyethylene (LLDPE) and low density polyethylene (LDPE) are mixed in proportion to blow film, combining their advantages, effectively improving the transparency and tensile strength of PE blown film; The stability of PE film can be effectively guaranteed by adding main antioxidant and auxiliary antioxidant.

The achievement will be transformed through self investment and will be successfully transformed in 2019. The achievement is provided with high-density polyethylene layer, carbon fiber layer, polyvinyl alcohol layer and cross-linked polyethylene layer, which ensures that the PE film has stable ductility and station viscosity.

The achievement will be transformed through self investment and will be successfully transformed in 2020. By changing the composition and proportion of the core layer, middle layer and surface layer, the tensile strength, elongation at break and heat sealing strength of the PE film have been significantly improved. The packaging bag made with the PE film as the base material can withstand cooking at 115 ℃, and its friction coefficient is reduced. The smoothness and flatness of the film surface have been significantly improved.

The achievement will be transformed through self investment and will be successfully transformed in 2020. Through the design of polyolefin elastic fiber in the ductile layer group, the achievement makes polyolefin elastic fiber use its own elasticity, 500% breaking elongation and 220 ℃ high temperature resistance to make the entire PE film more elastic after packaging, and at the same time, it can automatically recover after pulling to avoid the fracture or deformation of the PE film, thus increasing the practicality of the product.
