Polyethylene can be divided into high density polyethylene, low density polyethylene and linear low density polyethylene according to the polymerization method, molecular weight and chain structure.
Linear Low Density Polyethylene (LLDPE) is a copolymer of ethylene and a small amount of advanced olefin in the presence of catalyst.LLDPE is similar to LDPE in appearance, with poor transparency and good surface gloss. LLDPE has the advantages of low temperature toughness, high modulus, bending resistance and stress cracking resistance, and good impact strength at low temperatuCE
