Material formulation development
We adjust the formulation around product structure, processing and use requirements, then arrange sample trials.

Green Free Plast turns natural cassava starch into a degradable material (PFM masterbatch) with self-developed patented technology: 83% biobased, 100% PLA-free. Made into mulch film, packaging bags, tableware and daily goods — it decomposes naturally after use, leaving no microplastics.

Certification, test and intellectual-property documents are provided for specific products and target markets. Tested by ITRI to GB/T 35795-2017, with multi-country patents and international composting certifications.
Meets GB/T 35795-2017. No retrieval after use — plough directly into the field, where it decomposes naturally into water and carbon dioxide. Degradation period can be tuned to crop requirements.
