Specification :

polyethylene , widely used plastic. It is a polymer of ethylene, CH 2 --CH 2 , having the formula ( -CH 2 -CH 2 -) n , and is produced at high pressures and temperatures in the presence of any one of several catalysts, depending on the desired properties for the finished product. Polyethylene is resistant to water, acids, alkalies, and most solvents. HDPE Plastic Bags is types of plastic which classified on its density and branching.HDPE is defined by a density of greater or equal to 0.941 g/ cm3. HDPE has a low degree of branching and thus stronger intermolecular forces and tensile strength. HDPE can be produced by chromium/ silica catalysts, Ziegler-Natta catalysts or metallocene catalysts. The lack of branching is ensured by an appropriate choice of catalyst ( for example, chromium catalysts or Ziegler-Natta catalysts) and reaction conditions. Plastic bags HDPE is suitable use for hot liquid packaging.
