POF shrink film is easy to apply multi-layer thin, imported PE and PP as the main raw materials and the necessary functional additives such as slip agent, anti-adhesive agent, anti-static agent, etc. by co-extrusion blow molding process production, I believe we are already familiar with POF shrink film, but POF shrink film manufacturers or to introduce you to the production process of POF shrink film, we all look at it together.
POF shrink film is linear low-density polyethylene and copolymer polypropylene as the main raw material, the processing, and the product application process does not produce odor, product hygiene performance in line with standards can be used for packaging food. These necessary raw materials to add the necessary additives, processed by co-extrusion blow molding process, the process is different from the traditional blow molding process, due to the poor tensile properties of PP melt state, and therefore can not use the traditional blow molding process, and the use of double film bubble process, it is the raw materials by different extruders melt extrusion, through the design of the co-extrusion die, the formation of the initial film after quenching, and then after heating the second blow stretching process to make POF shrink film.
The above is the POF shrink film manufacturers to introduce you to the knowledge of POF shrink film, thank you for viewing our news in a busy time, POF shrink film is one of our main products, thank you for choosing our products, let us make progress together!
