Green bio-based starch degradation masterbatch compounding pelletizing line



Equipment configuration description

Bio-based starch degradation masterbatch for film-bags, meal box and packaging fields etc.

Formula system:


Code Raw material Blown film bags Blown sheet  

Degradable resin


50-65% 25-30%  
2 Starch filling (modified) 20-30% 40-50%  
3 CaCO3 filling 10-15% 10-15%  
4 Additives (Food grade) 5-8% 5-8%  

Process requirement:

All materials required deep drying, it required fully dispersed, distributed and uniformly mixed in the extrusion compounding process to ensure the stretch strength and elongation at break etc the physical index of the products to meet blown film and vacuum forming. The equipment can choose co-rotating parallel twin screw extruder, twin screw extruder configured with high torque, long L/D from 48-52:1, special optimized screw arrangement design, effectively ensure the temperature control and avoid to generate shearing heat to cuase the melt pre-degrade, at the same time, up to the best compounding extrusion status.

The discharging end equiped with screw melt pump for cooling and pressure built-up, it is benefit for pelletizing and improve the product quality. The pelletizing system can use die face hot cutting in order to avoid it touch with water.

In order to increase the toughness and increase the elongation of the section, and much more effectively complete blown film bag making and sheet vacuum forming process, a small amount of PP or PE is added to the resin to realize the bio-based starch filling degradable masterbatch. The degradable masterbatch produced by Cenmen’s equipment line has a degradation rate of about 90% (the degradation rate of general degradable masterbatch can only reach about 70%). The degradable masterbatch produced can reach the degradation standards of industries in various countries and regions, and its production process and configuration are basically the same as those of fully degradable masterbatch.

At present, the degradable masterbatch pelletizing line equipment manufactured by Cenmen company has been widely used in Jiangsu, Guangdong and other regions, and exported to India, Australia, Ukraine, Russia and other countries.
