How to achieve the effect of POF shrink film?

Shrink film is a new type of environmentally friendly packaging material with high transparency, high shrinkage, high toughness, high heat sealing and antistatic properties. It is a relatively safe soft shrink packaging material. There are many types of shrink films on the market, among which POF shrink film has gradually become the mainstream of shrink packaging due to its non-toxic, environmentally friendly, high transparency, high shrinkage, good heat sealing performance, high gloss, strong toughness, and tear resistance. Therefore, there are many POF shrink film factories on the market, and the product quality is also good and bad.

When many customers who use POF shrink film find that the packaging effect of POF shrink film is poor, that is, the shrinking effect is not good, they generally think that there is a problem with the quality of POF shrink film. There is a misunderstanding here. In fact, there are many factors that affect the shrinking effect of POF shrink film, and the poor quality of POF shrink film is not the only factor. Here, the editor briefly introduces several factors that affect the shrinking effect of POF shrink film.

Most people find that the shrinking effect is poor when using POF shrink film. It is not surprising that the quality of POF shrink film itself is poor. The quality of POF shrink film directly affects its shrinking effect. For example, there are obvious differences in transparency and shrinkage between POF shrink film made of new materials and POF shrink film doped with recycled materials. The cost and price of POF shrink film made of doped recycled materials on the market are lower than the former, so it is common to see inferior products being sold as good ones.

Secondly, the shrinking temperature of POF shrink film affects the shrinking effect. The shrinking effect is related to the actual shrinking temperature. Too high a temperature can easily cause shrinkage and cracking of the plastic film; when the temperature is low, the shrinking effect of POF shrink film is uneven. Therefore, manufacturers need to adjust the temperature several times when producing POF shrink film to find the most suitable temperature value.
