LDPE Film Static Electricity Problem
Problem Phenomenon
The film roll has large static electricity, adsorbing dust and sparking during machine running.
Cause Analysis
LDPE has strong insulation, and frictional charging is hard to release; dry environment aggravates it.
Solution
①Install static eliminators; ②increase ambient humidity; ③treat the film surface with antistatic agent; ④ground the equipment.
Key Takeaway
Static electricity = the three-piece set of eliminator + humidity + grounding.
