Static electricity problem of BOPP film
Problem Phenomenon
During high-speed production, the film attracts dust and is difficult to handle, and electrostatic discharge is obvious in dry seasons.
Cause Analysis
High-speed friction and a dry environment cause static electricity to accumulate on the film surface; electrostatic attraction of contamination also affects printing and laminating quality.; during on-site investigation, verify item by item according to this mechanism to avoid blindly adjusting the machine based only on experience
Solution
①Add antistatic masterbatch or perform antistatic treatment; ②install ionized air static elimination devices; ③control workshop humidity; ④standardize grounding.; after adjustment, continuously sample and verify the effect, and resume mass production after confirming stability
Key Takeaway
Static management is a necessary condition for BOPP high-speed production; material antistatic and environmental control work together.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
