But we must know how to judge the quality of pvc heat shrinkable film, then from what aspects to judge the quality of pvc heat shrinkable film is qualified?
First of all, look at the transparency and gloss of the pvc heat shrinkable film. High quality pvc heat shrinkable film has good transparency and gloss. If you look in the sun, there is not much impurities;
Second: the shrink film with good quality shrinks quickly when it is packaged through the heat shrinkable film. On the contrary, the shrink film with poor quality shrinks poorly, or it needs to be heat-shrinked two or three times to complete the shrinking process;
Third: sealing performance, when the shrink film passes through the heat shrinkable film packaging machine, the PVC heat shrinkable film will be broken, wrinkled or have small holes, which is caused by poor sealing performance. The high-quality PVC heat shrinkable film has good sealing performance. After the heat shrinking process is completed, it is very beautiful and can truly achieve the desired shrinkage effect;
Fourth: anti-puncture performance, that is to say, the shrink film plays the protective role we want during the transportation of the product. High quality shrink film has high puncture resistance and is not easy to pierce;
Fifth: The shrinking memory function is strong, and the shrinking tightness is good. It is reflected in the protection of the product when the whole product and parts shrink packaging, and the package is not scattered or the packaging is incomplete. This is similar to the second point.
