Although LLDPE and LDPE in the past belong to the same density range, their basic physical properties and molding processing characteristics are different due to their different molecular structures and melting rheological behaviors.

Linear low density polyethylene (LLDP) resin is called the third generation polyethylene. In addition to the performance of general polyolefin resin, its tensile strength, tear strength, environmental stress cracking resistance, low temperature resistance, heat resistance and puncture resistance are particularly superior.
