Biodegradable & Compostable Resins Supplier China — PLA · PBAT · PHA · PBS · PCL
Biodegradable and compostable resin pellets for film extrusion, injection molding, blow molding, 3D printing filament, and food-contact packaging. We supply seven core grades — PLA, PBAT, PHA, PHB, PHBV, PBS, and PCL — from China tier-1 manufacturers with documented EN 13432, ASTM D6400, and FDA food-contact compliance.
Single-use plastic regulations in the EU (SUPD), China, Korea, Japan, and a growing list of U.S. states are pushing brand owners away from conventional PE/PP/PET in bags, cutlery, straws, food containers, agricultural mulch film, and mailer packaging. Our portfolio covers the three families converters typically blend: rigid PLA for stiffness and clarity, flexible PBAT for toughness and tear strength, and PHA/PHB/PHBV for industrial compostability and marine biodegradability claims. PBS and PCL round out the range as bio-based specialty polyesters for higher-heat or slower-degradation niches.
Direct sourcing from China tier-1 manufacturers. FOB Shanghai or CIF major ports. 25 kg MOQ. Free TDS, MSDS, RoHS, REACH, FDA, EN 13432 documentation on request. 24h quote response.
Why Biodegradable & Compostable Resins?
Conventional plastics persist in the environment for decades to centuries. Biodegradable and compostable resins are designed to mineralize under specific conditions — industrial composting, home composting, soil burial, or marine environments — within weeks to a few years, depending on grade and environment. This makes them a regulatory and brand-positioning fit for:
| Property | Conventional PE/PP/PET | Biodegradable Resins |
|---|---|---|
| Environmental persistence | 50–600 years (land/sea) | ~90 days to 24 months (industrial composting, depending on grade) |
| Carbon source | Fossil (oil/gas) | Renewable (corn starch, sugarcane, cassava, vegetable oil) and/or CO2 |
| End-of-life options | Landfill, incineration, mechanical recycle (often downcycled) | Industrial composting, home composting (PLA/PBS grades), anaerobic digestion, in some cases mechanical recycle |
| Regulatory fit (SUPD, EPR) | Restricted for single-use in many jurisdictions | Accepted under EN 13432 / ASTM D6400 frameworks |
| Marine biodegradation | None | PHB/PHBV grades — yes, certified |
| Cost (per kg) | $0.8–1.5 | $1.8–6.0 (varies by grade) |
Important caveat: not all biodegradable resins are compostable. PLA is industrially compostable but not home-compostable in cold climates; PBAT is biodegradable in soil but not industrially compostable above 90% mineralization; PHA/PHB/PHBV are both biodegradable and industrially compostable. We will help you match the right grade to your end-of-life claim and target market.
