Control of dissolution rate abnormality in PEOX cast film water-soluble bags
Problem Phenomenon
During PEOX cast film production of water-soluble bags, the problem of not up to standard dissolution rate occurs.
Cause Analysis
Mainly due to the processing temperature deviating from the window +60-100°C, moisture content >0.1% 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.
