How to eliminate static electricity in packaging printing? It is necessary to adopt different antistatic technologies to eliminate static electricity in combination with the actual production, the use of packaging materials (what products to pack), and the customer's use conditions. Common antistatic technologies are as follows:

1. Physical elimination method The physical elimination method is a method of eliminating by using the inherent characteristics of static electricity without changing the function of the material. For example, the grounding elimination method is to install a static-dissipating brush on the process. Place the brush body at the rewinding or unwinding place of the paper or plastic coil, and make the grounding end of the anti-static brush reliably ground, and cannot be connected to the equipment or the guide roller. Because the equipment may be poorly grounded; some guide rollers are anodized, and the surface is naturally made of aluminum oxide, which is non-conductive.

2. Chemical elimination method The chemical elimination method is the antistatic agent treatment technology, which is mainly a method of modifying the electrical energy of the resin or substrate by adding (filling) technology or coating technology to the antistatic agent (surfactant). , is a more thorough and perfect antistatic technology. However, due to the addition or coating of antistatic agents, the chemical composition of the material is changed, so this technology is not suitable for the treatment of paper, but only for the modification of plastic resins.
