Production Process of POF Shrink Film

POF shrink film, as a substitute for traditional shrink film, is mainly used for packaging regular and irregularly shaped products. With high transparency and good glossiness, it can clearly display the appearance of the product, enhance sensory awareness, and reflect its high quality, making it widely welcomed. For your convenience, let's introduce the production process of POF shrink film.

Shrink film is mainly made from linear low-density polyethylene and copolymer polypropylene (TPP, PPC) as the main raw materials, with necessary additives added, and processed through co-extrusion blow molding technology. It mainly adopts the double bubble process, also known as the Prandi process internationally. This process involves melting and extruding the raw materials through different extruders, forming the primary film through a specially designed co-extrusion die, rapid cooling, and then undergoing secondary blow expansion and stretching processes to produce the final product.

The above is an introduction to the production process of POF shrink film. According to this introduction, it can better ensure the use of the product, fully exert its characteristics such as energy saving, high shrinkage rate, transparency, glossiness, and strong tear resistance. Moreover, this product has overturned the limitations of traditional packaging films and is deeply welcomed by the market.
