Polyolefin Shrink Film(POF) is now the most widely used shrink packaging materials,The main composities of the film are Polypropylene (PP) and Linear Low DensityPolyethylene(LLDPE).
These materials are non-toxic and non-smelly Environmentally Friendly type (POF) 5-Layer Co-extruded Polyolefin Shrink Film produced by our company are featured with high constriction ratio (over 60%), moderate air barrier property, flexible tenacity and hermetic sealing property,low-temperature resistance,non-brittle,damp-proof and anti-static.It is suitable for automatic or semi-automatic shrink pack machines.
1. Shrinkage rate : crosswise 20% – 30%,lengthways 65% – 75%.
2. High glossy, high transparency,Perfact Adornment performance.
3. Flexible performance is good, improver under Low temprature, Not easy aging.
4. The low density of the POF Shrink Film Can effectively reduce the packaging cost.
5. Heat sealing performance is outstanding,sealing strenth high.
6. Tensile, resistance to puncture good performance.
7. Use range, can use in semi-automatic, automatic high-speed packaging equipment and manual packaging.
