POF film we produces ,five-layer polyolefin oriented film, is firstly extruded by five extrusion machines prior to ordinary POF using the materials of both linear low density polyethylene(LLDPE) and polypropylene, then molded into being by special process of mold forming and film bubble inflation. It is this product that assumes the properties of friendliness to environment, high transparency, high shrinkable rate, superb heat sealing, high-gloss surface ,well-extendedness, heat shrinkable uniformity and suitableness for high-speed automatic packaging. As a result, it becomes the best replacement of the traditional PVC hot shrinkable film.
