Biodegradable plastics, refer to the action of microorganisms existing in nature under natural conditions such as soil or sand, or specific conditions such as composting conditions or anaerobic digestion conditions or aqueous culture solutions. Plastics that cause degradation and ultimately complete degradation into carbon dioxide (CO₂) or/and methane (CH₄), water (H₂O) and the mineralized inorganic salts of the elements it contains, and new biomass.

Bio plastics are a large family of different materials, not just one material. They consist of a whole family of materials with different properties and applications. According to European Bioplastics, plastic materials are defined as bioplastics if they are bio-based, biodegradable or both.
Starch Based Bio-degradable Compounds
Starch is one of the most promising natural polymers because of its inherent biodegradability, overwhelming abundance and annual renewability. Starch is wildly used due to their low material cost and ability to be processed with twin screw compounding extruders. Starch/PLA /PBAT are some of the most common biodegradable compounds used in packaging and agricultural applications.
Mineral Based Bio-degradable Compounds
Xinda compounding extruders have been widely used for mineral based bio-degradable compounds. Mineral fillers have always been used with compostable polymers such as PLA/PBAT/PBS to reduce the cost, promote the thermal and dimensional stability of the material, and contain its shrinkage and deformations generated by the conversion processes.
Biodegradable Compounds:
With extensive experience in the plastic compounding industry, together with broadly based Xinda process expertise in compounding, make Xinda a pioneer in the biodegradable plastics industry.
Xinda twin-screw extruder adopts modular design, and its main advantage is multi-functional configuration.Processing tasks can be optimally accomplished with only a few barrel and screw variations. We will make the detailed solution according to your specific application for Bio-degradable products.
Xinda Twin-screw extrusion lines offer major advantages for manufacturing biodegradable compounds:
- process flexibility, reduced downtime between batches and simple product changeover.
- dedicated screw profiles for homogenous mixing quality.
- Moderate shear and low shear stress without destroying delicate fillers.
- Using high-accuracy gravimetric feeders to introduce the raw materials into the twin screw extruder, which can reliably feed biomas with poor liquidity such as starch.
