Environmental humidity influence on BOPP film
Problem Phenomenon
In high-humidity seasons, film quality fluctuates and performance decay after treatment accelerates.
Cause Analysis
Environmental humidity affects the durability of the corona treatment effect and the electrostatic behavior; contaminants are more likely to adhere to the film surface as humidity changes.; during on-site investigation, verify item by item according to this mechanism to avoid blindly adjusting the machine based only on experience
Solution
①Maintain a controlled production environment; ②monitor workshop temperature and humidity; ③use as soon as possible after treatment or store sealed; ④strengthen environmental cleanliness management.; after adjustment, continuously sample and verify the effect, and resume mass production after confirming stability
Key Takeaway
Environmental management is an invisible variable of BOPP quality; a constant-temperature and constant-humidity workshop is the standard configuration for high-end film production.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
