Control of strength abnormality in PEOX coating water-soluble bags
Problem Phenomenon
During PEOX coating production of water-soluble bags, the problem of not up to standard strength occurs.
Cause Analysis
Mainly due to the processing temperature deviating from the window +70-90°C, moisture content >0.3% exceeding the standard, and insufficient cooling.
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.
