I believe that we have all encountered static electricity when using stretch films. It is also very common in our daily life. Here, our editor would like to share with you about the problem of static electricity in stretch films, find out what factors are involved so you can use them better.
Stretch film will carry static electricity with these factors:
1. The production of static electricity because of the friction between the particles, melt and die friction, film rolling friction and guide roller, as a result, the film produces static electricity when it leaves the factory. Black tensile film manufacturers remind that in the process of tensile film production to add antistatic agent to eliminate this part of the static electricity. It should be said that the effect is still very good.
2.When printing, compounding, slitting and bag-making, the static electricity is produced because of the friction between the drawing film and the guide roller, the friction between the high-speed stretch film and the dry air, etc. . Black stretch film manufacturers remind you that this part of the static electricity on the production is the largest, and if not effectively eliminate, on the post-processing process will be a great impact. In general, the use of a superconducting electrostatic brush (contact elimination) is more effective, it is in contact with the tensile film, this problem is solved by grounding the resulting electrostatic charge through a brush with a very low resistance (1 m wide resistance less than 1) .
3. The friction between the static electricity film and the guide roller of the equipment, the static electricity is not completely eliminated by the film itself. Causes the automatic packing difficulty as well as needs the content to the static electricity sensitivity, at this time also may take the above method to carry on the elimination static electricity. The most effective method is also the use of superconducting electrostatic brush method to eliminate.
