Customer Pain Points：

1. Film surface absorbs dust during unwinding, affecting subsequent processes

2. Charged film adsorbs fine dust during coating, resulting in uneven coating thickness

3. Massive static charge on multi-layer materials during lamination brings explosion risks

4. Excessive static during winding causes static shocks to workers and misaligned, uneven roll end faces

Solution：

Install explosion-proof static eliminating bars at key stations including unwinding, coating head and laminating rollers to stabilize static charge within a safe range, ensuring coating cleanliness and optical performance.

For winding stations with limited installation space, medium/long-distance DC static eliminators are available to neutralize static at 100–500mm or 200–1500mm working distances and achieve flat film rolls
