Control of winding abnormality in PEOX blown film bandages
Problem Phenomenon
During PEOX blown film production of bandages, the problem of unstable winding occurs.
Cause Analysis
Mainly due to the processing temperature deviating from the window +65-95°C, moisture content >0.5% 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 strengthen cooling.
Key Takeaway
PEOX processing requires precise control of the three elements of temperature, humidity, and residence time.
