Control of winding abnormality in PEOX blown film packaging
Problem Phenomenon
During PEOX blown film production of packaging, the problem of uneven winding occurs.
Cause Analysis
Mainly due to the processing temperature deviating from the window +60-100°C, moisture content >0.3% exceeding the standard, and shear heat accumulation.
Solution
Strictly control the temperature within the recommended range, fully dry the material to moisture content <0.1%, and reduce the screw speed.
Key Takeaway
PEOX processing requires precise control of the three elements of temperature, humidity, and residence time.
