How does POF heat shrinkable film achieve shrinkable effect

When many customers using POF heat shrinkable film find that the packaging effect of POF shrinkable film is not good, that is, the shrinkable effect is not increased, it is generally considered that the quality of POF heat shrinkable film has problems. There is a misunderstanding here. In fact, there are many factors affecting the shrinkage effect of POF shrink film, and poor quality of POF shrink film is not the only one. Here, we, Shenkai packaging, a professional POF heat shrinkable film factory, will briefly explain several factors that affect the shrinkage effect of POF shrinkable film.

  Firstly, most people find that the shrinkage effect of POF heat shrinkable film is not good when they use POF heat shrinkable film. First of all, they think that the poor quality of POF heat shrinkable film itself is not surprising. The quality of POF heat shrinkable film really directly affects its shrinkage effect. For example, there are obvious differences in transparency and shrinkage between POF shrink film made of brand-new materials and POF shrink film made of dopant recycled materials. The cost and price of POF shrink film made of dopant recycled materials on the market are lower than the former, so it is not uncommon that it is inferior.

  Shrink film is a new type of environmental protection packaging material, which has high transparency, high shrinkage, high toughness, high heat sealing performance, and anti-static, is a relatively safe soft shrink packaging material. There are many kinds of shrinkable films on the market, among which POF shrinkable film has gradually become the mainstream of shrinkable film packaging, because of its non-toxic, environmental protection, high transparency, high shrinkage, good heat sealing performance, high gloss, strong toughness, tear resistance and other characteristics.    Therefore, there are many POF heat shrinkable film factories on the market, and the quality of their products is also uneven.

  Secondly, the shrinkage temperature of POF heat shrinkable film is relatively wide, and the shrinkage effect is related to the actual shrinkage temperature. Too high temperature is easy to lead to the cracking of POF heat shrinkable film; low temperature will lead to uneven shrinkage effect of POF heat shrinkable film.

  But no matter what, as a professional POF heat shrinkable film production factory, we should be alert to the POF heat shrinkable film production process, and ensure the product quality is not only responsible for customers, but also for our own reputation.
