What are the important factors when using PVC

PVC heat shrinkable film has good shrinkage, low price, high transparency, and high cost performance. These are all important elements that users consider first before using. The second is the temperature required during the shrinking process when using shrink film.

The working principle of PVC heat shrinkable film is actually relatively simple to operate. As long as the speed and temperature match, it is OK. If the temperature is low, the product surface will appear wrinkles after shrinking, and if the temperature is too high, the shrink film will There is a possibility of being scalded.

Finally, it depends on whether the size of the furnace is appropriate. The furnace does not meet the standard in two cases: one is that the furnace is too large, and the other is that the furnace is too small. Excessive furnace path will cause uneven heating of the packaged products, which will cause good shrinkage on one side and bad shrinkage on the other side. If the furnace path is too small, the shrink film leaking from the edge will stick to the inner wall of the furnace path and be scalded. Bad.
