Biodegradable modified film grade PLA resin.


Biodegradable modified film grade PLA resin



Product Introduction


The Modified film grade PLA resin is an alloy of PLA and PBAT. Using PLA as the base material and chemical modification process, another biodegradable resin PBAT and PLA were linked to each other, which greatly increased the flexibility and tensile properties of PLA. so that the application of PLA in blowing film can be achieved.





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.


 Quick details 




Application examples

The film made with modified film grade PLA  can be used to make below products:

Bags: shopping bags, packaging bags, storage bags, garbage bags, rolling bags and etc;

Disposable products: disposable gloves, tablecloths, aprons, raincoats.






 Note: The above technical parameters are typical performance indicators, not specific product quality assurance. 




 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 rad/min

  • Inflation ratio: 2-4
