Hazards of Static Electricity in Flexible Packaging Production
In the printing process, accidents that may occur due to untreated static electricity include sparks causing ink and solvent fires, leading to a potential fire hazard. Static electricity can cause fuzzing at the edges of printed patterns. It can also result in poor leveling of ink on the film, causing patterns to appear intermittent, as if they are not printing properly. Additionally, static electricity can lead to uneven winding during the rewinding process.
During the composite process, accidents that may occur due to static electricity include sparks causing adhesives and solvents to ignite, creating a fire hazard. Static electricity can also lead to uneven winding of composite films. Since static electricity is not completely discharged during printing, bubbles may form at the edges of patterns during the composite process.
Measures for Eliminating Static Electricity in Flexible Packaging Enterprises
Strengthening the establishment of safety awareness among employees and providing safety training for operators.
When the weather is dry, increase humidity in the production area to eliminate static electricity.
Enhance efforts to eliminate static electricity by installing effective grounding devices and static eliminators.
When using gold or silver ink in printing, choose inks produced by reputable manufacturers, as they may contain antistatic agents, significantly reducing the generation of static electricity.
When printing on polar films (NY, PET), consider adding solvents with antistatic properties, such as isopropanol or acetone, to the diluting solvent to eliminate static electricity.
Lowering machine speed and reducing the tension during winding and unwinding can also help eliminate some static electricity.
