In daily life, many PE plastic bags are used to package products, but there are many types and names of packaging materials. When we need to use PE plastic bags, how do we identify them? PE film is widely used to make plastic bags, plastic films and milk pails. Its name is also polyethylene, which is resistant to a variety of organic solvents, acid and alkali corrosion, but not antioxidant acids, such as nitric acid. Polyethylene will be oxidized in oxidizing environment. Polyethylene can be considered transparent in the film state, but in the presence of a large number of crystals in the block, it will be opaque due to strong light scattering. The degree of crystallization of polyethylene is affected by the number of its branches. The more branches, the more difficult it is to crystallize. The melting temperature of polyethylene crystal is also affected by the number of branches and chains, which are distributed from 90 ℃ to 130 ℃. The more branches and chains, the lower the melting temperature. Polyethylene single crystals can usually be prepared by dissolving high-density polyethylene in xylene at temperatures above 130 ℃.
