Control of appearance abnormality in PEOX hot pressing water-soluble bags
Problem Phenomenon
During PEOX hot pressing production of water-soluble bags, the problem of uneven appearance occurs.
Cause Analysis
Mainly due to the processing temperature deviating from the window +60-100°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 shorten the residence time.
Key Takeaway
PEOX processing requires precise control of the three elements of temperature, humidity, and residence time.
