The shrink film of POF/PE/PVC is a relatively common shrink film, so which one has a better shrinkage rate? At what temperature does it contract? Broad one small part to introduce to everybody!
POF has a high shrinkage rate, up to 75%, good flexibility, and can be used for packaging of any shape of goods. Moreover, the shrinkage of the five-layer co-extrusion POF film processed by special technology can be controlled to meet the shrinkage requirements of different commodity packaging. Good welding sealing performance, high strength, suitable for manual, semi-automatic and high-speed automatic packaging, shrinkage temperature: 130-150 degrees;
PE heat shrink film shrinkage rate transverse 10%-30%, longitudinal 30%-50%, widely applicable to wine, can, mineral water, a variety of drinks, cloth and other products of the whole package, the product flexibility, anti-impact, anti-tear, not easy to damage, not afraid of the tide, shrinkage temperature is about 200 degrees;
PVC heat shrink film shrinkage: transverse 35-45%, longitudinal 20-25%, has a unique rainproof, dustproof, insulation, easy to form performance and PVC low investment and high yield characteristics, is widely used in the building materials industry and packaging industry, and has high transparency, good gloss, shrinkage high characteristics. The contraction temperature is 80-100 degrees.
