Control of demolding abnormality in PEOX blown film pharmaceutical films
Fenómeno del problema
During PEOX blown film production of pharmaceutical films, the problem of unstable demolding occurs.
Análisis de la causa
Mainly due to the processing temperature deviating from the window +60-100°C, moisture content >0.5% exceeding the standard, and shear heat accumulation.
Solución
Strictly control the temperature within the recommended range, fully dry the material to moisture content <0.1%, and strengthen cooling.
Conclusión clave
PEOX processing requires precise control of the three elements of temperature, humidity, and residence time.
