Control of appearance abnormality in PEOX calendering packaging
Problem Phenomenon
During PEOX calendering production of packaging, the problem of unstable appearance occurs.
Cause Analysis
Mainly due to the processing temperature deviating from the window +65-95°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.
