When many customers using POF shrink film find that the packaging effect of POF shrink film is poor, that is, the contraction effect is not good, it is generally believed that the quality of POF shrink film is wrong. 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 factor. Here, Xiaobian briefly describes several factors affecting the effect of POF shrink film shrinkage.
First, most people use POF shrink film, found that the contraction effect is poor, POF shrink film itself poor quality is not surprising. The quality of POF shrink film does directly affect its shrink effect. For example, the POF shrink film of new material and POF doped recovery material have obvious differences in transparency and shrinkage. On the market, POF shrink film made of doping recycled materials, the cost and price are lower than the former, so the phenomenon of shoddy good is not uncommon.
Secondly, the shrinkage temperature of POF shrinkage film is affected. Shrinkage effect is linked with the actual shrinkage temperature, too high temperature is easy to cause shrinkage cracking of plastic film; When the temperature is low, the contraction effect of POF shrink film will be uneven. Therefore, the manufacturer needs to adjust the temperature many times in the production of POF shrink film to find the most appropriate temperature value.
