Analysis of the problem of static electricity generated by stretched film

In the process of producing stretch film, static electricity is sometimes generated. This phenomenon can be caused by many aspects, so it still needs specific analysis.

One reason is the friction between the pellets, the friction between the melt and the die, and the friction with the guide roller during film forming and winding, which causes the film to generate static electricity when it leaves the factory. Therefore, in the production process of the stretch film, it is necessary to add Antistatic agent to eliminate this part of static electricity.

In the process of printing, compounding, slitting, and bag making, static electricity may also be generated, mainly because of the friction between the stretch film and the guide roller, the friction between the stretch film running at high speed and the dry air, etc., which make the stretch film Static electricity is generated, and this part of static electricity has the greatest impact on production, and if it cannot be effectively eliminated, it will also have a great impact on the success of the post-processing process.

Then there is the friction between the finished stretch film and the guide roller of the equipment, the stretch film itself has not been completely eliminated static electricity and other reasons, resulting in difficulties in automatic packaging and the required content is sensitive to static electricity. The most effective way is to use superconducting electrostatic brushes method to eliminate.
