Static Electricity Application Solution for Blown Film Machines in Flexible Packaging Industry

During blown film extrusion, hot films freshly extruded from dies continuously accumulate static via friction against guide rollers and press rollers throughout cooling setting, traction transport and winding processes, triggering diverse production malfunctions.

① Operator electric shock hazards High voltage static on film surfaces discharges when operators approach or touch take up assemblies or moving webs, producing perceptible electric shocks ranging from mild tingling to disrupted workflow, creating safety risks and impairing operator performance.

② Film surface dust contamination and degraded finishedpart quality Static attracts airborne dust, lint and impurities that cling tenaciously to film surfaces. Resulting surface specks and blemishes undermine subsequent printing, lamination and coating steps and push defectiveproduct ratios upward.

③ Uneven winding, web wandering & wrinkling, higher material loss Electrostatic repulsion or adhesion between film layers creates uneven tension during winding, manifesting as inconsistent roll tightness, misaligned edges and web wandering. In severe cases, web wrinkling, tensile deformation or web breakage and machine shutdown follow, wasting raw materials and slowing production throughput.

For blown film machine operating conditions characterized by high bubble height, large static neutralizing distances and constrained installation space, the Yanping XK-860B long range intelligent DC static eliminator is recommended. Optimized for long distance charge neutralization, it delivers effective working distances from 200 mm to 1500 mm. It neutralizes static rapidly without physical proximity to film surfaces. Flexible mounting options prevent contact with film bubbles and support diverse blown film machine models and factory layouts.

After static elimination, films remain clean and contaminantfree. Film bubbles run stably without oscillation, and finished rolls are wound neatly and tightly free of wandering and wrinkling. Workplace operational safety is also enhanced.
