It has high tensile strength and tear resistance, as well as a certain degree of self-adhesiveness and high transparency, which can prevent goods from falling apart and collapsing during transportation. PE stretch film is widely used in mining, building materials, auto parts, wires and cables, chemicals, metal products and other industries because the wrapped objects are beautiful and elegant, and can be dust-proof, moisture-proof, and vandal-proof. The base material of PE stretch film is mainly LLDPE, including C4, C6, C8 and metallocene PE (MPE). With the increasing awareness of environmental protection, metallocene PE (MPE) has become a new benchmark in the packaging industry due to its excellent physical and processing properties.
