With the increase of the deformation rate of polyethylene, LDPE shows an amazing increase in viscosity, which is caused by molecular chain entanglement. This phenomenon cannot be observed in LLDPE, because the lack of long branched chains in LLDPE makes the polymer not entangled. This property is very important for thin film applications. LLDPE films are easier to make thinner films while maintaining high strength and toughness.

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.
