Machine use Pre-stretch film:
The film use linear low density polyethylene as the main raw material and the skill is three- layer extrusion casting skill. Our film has reached the international advanced level in each technical indicator, such as uniform film rolls, excellent tensile properties, high retraction rate, transparency and tearing strength. The film can self-adhesive at room temperature as well. The film is from 15 um to 50 um in thickness, width from 50mm ~ 1500m and the width can be slit to any sizes as requested. The film can be sub-sided sticky or double-sided sticky. Machine use Pre-stretch film is widely used in building materials, chemicals, glass, ceramics, electronics, metal, auto parts, wire, paper, canning, daily necessities, food and other industries, so as to achieve moisture and dust proof, reduce labor, improve efficiency and reduce costs.
