The quality of PE protective film will be seriously affected by what factors?
- Feb 19, 2019 -

It is important to examine the thickness of the PE protective film because it relates to the ability of the protective film to withstand impact forces. Generally, the thickness of the mask is preferably about 0.09 mm. If deep drawing is required, the thickness of the film should be increased accordingly, otherwise it will be broken down and damage the processed object. The thickness of the mask can be measured using a micrometer. It is not easy to accurately grasp by eyesight and hand touch, because the diameter of a hair is about 0.07mm, and it is difficult to achieve the sensitivity of the hand. In addition, do not store too much protective film, because the season change, temperature and humidity changes can affect the quality of the protective film. The protective film should not be exposed to the sun, nor should it be damp. It should be placed in a ventilated place.
