Biodegradable film grade PLA eSunBio4421C
Thebiodegradable film blowning material is a kind of alloy material based onbiological material. It can be used for blowing film to make all kinds ofpackaging products.
It is suitable for ordinary LDPE film blowing equipment;
Easy to blow film, good processing performance;
The film made of this material has good flexibility and tensile property.
Note: The above technical parameters are typical performance indicators, not specific product quality assurance.
5、Blow molding process
1） Pretreatment of the material
Generally speaking, it is not necessary for drying process, but if it is in damp circumstance, it need for drying treatment. Drying temperature: 65° C, drying time: 4 hours.
2） Process parameters
In the process of processing, the processing temperature should be strictly controlled.
Blow molding temperature: 150-180 ° C
Blown film thickness: 0.02-0.08 mm
Screw rotation speed: 30-80 RPM
Inflation ratio: 2-4
