PHA Pellets for Injection Molding — Virgin Resin Optimized for Fast Cycles
Virgin PHA resin grades formulated specifically for injection molding, with melt flow index in the 5-30 g/10min range to fill thin-wall tooling quickly and release cleanly. Because PHApack controls the process from indigenous bacterial strain cultivation through green extraction to compounding, the resin arrives at 99.5% purity with tight lot-to-lot consistency, which is what keeps cycle times stable and scrap rates low in production. Food grade is standard; medical grade is available on request. More than 50 formulations are held in the library, and trial orders start at 100 kg so processors can validate before committing to volume.
Key Benefits
- MFI 5-30 g/10min fills thin-wall and multi-cavity tooling without short shots
- Good mold release reduces cycle time and ejection marks
- Tight lot-to-lot consistency keeps process parameters stable across production runs
- 99.5% purity from in-house green extraction, no filler or regrind

Frequently Asked Questions About PHA Pellets for Injection Molding
What is PHA Pellets for Injection Molding made of?
PHA Pellets for Injection Molding is made from 100% PHA (Polyhydroxyalkanoates), a bio-based polyester produced by bacterial fermentation of renewable feedstock. Unlike petroleum-based plastics, PHA is derived from non-food plant sugars using Chinese indigenous bacterial strains. The material is certified by BPI, TUV Austria (OK Compost HOME, OK Compost MARINE), and DIN CERTCO for complete biodegradation in ocean, soil, home compost, and industrial compost environments.
How long does PHA Pellets for Injection Molding take to biodegrade?
PHA Pellets for Injection Molding biodegrades completely within 6-18 months in home compost. In industrial composting facilities (58°C+), degradation occurs in 3-6 months. In marine environments, complete biodegradation takes 1-3 years. The process produces only CO2, water, and biomass — no microplastics or toxic residues remain.
What certifications does PHA Pellets for Injection Molding hold?
PHA Pellets for Injection Molding holds BPI, TÜV OK Compost HOME, FDA 21 CFR, EU 10/2011, ISO 9001. These certifications verify that the product meets international standards for biodegradability, compostability, and food contact safety. PHApack products are tested per EN 13432, ASTM D6400, ISO 14855, and ASTM D6691 standards by independent laboratories.
What is the minimum order quantity and lead time?
The standard MOQ for PHA Pellets for Injection Molding is Trial orders from 100 kg, mass production from 1 ton. Lead time is typically 15-25 days standard, 25-35 days custom formulation after order confirmation. For custom OEM orders with specific dimensions, colors, or branded printing, lead time may extend to 25-35 days. Trial orders from 100kg are available for evaluation.
Can PHA Pellets for Injection Molding be customized with our brand logo?
Yes, PHApack provides full OEM/ODM services for PHA Pellets for Injection Molding. Customization options include custom dimensions, colors, flexographic printing up to 6 colors, private label packaging, and branded embossing.
