POF is a multi-layer co-extruded environmentally friendly polyolefin heat shrink packaging material. The film is processed using the double bubble method, using LLDPE as the middle layer material and ternary co-polypropylene as the inner and outer layer materials, and produced through three-layer co extrusion composite production

POF has significant characteristics such as high transparency, high shrinkage rate, and good sealing performance. It has the advantages and advantages of both PP film and PE film, so its product performance far exceeds that of pure PP film and PE film. It is currently widely promoted in the international market and recognized as an environmentally friendly heat shrink film packaging material in the European and American markets
