PHA Pellets for Film Extrusion — Blown and Cast Film Resin
Virgin PHA resin grades for blown and cast film lines, with melt flow index in the 1-10 g/10min range to give the melt strength needed for stable bubble formation and consistent gauge. PHBV and P34HB grades are supplied for different film performance targets: PHBV offers higher stiffness and barrier for packaging film, while P34HB gives better elongation and toughness for bags that must carry load. All grades are marine biodegradable and home compostable, which is what allows finished film products to carry TÜV and BPI certification rather than an industrial-compost-only claim.
Key Benefits
- PHBV grades deliver stiffness and oxygen barrier for packaging film
- P34HB grades deliver elongation and tear resistance for load-bearing bags
- MFI 1-5 blown grades give stable bubble and low gauge variation
- MFI 3-10 cast grades flow well for thin-gauge and lamination base film

Frequently Asked Questions About PHA Pellets for Film Extrusion
What is PHA Pellets for Film Extrusion made of?
PHA Pellets for Film Extrusion 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 Film Extrusion take to biodegrade?
PHA Pellets for Film Extrusion 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 Film Extrusion hold?
PHA Pellets for Film Extrusion holds BPI, TÜV OK Compost HOME, OK biodegradable MARINE, OK biodegradable SOIL, EN 13432. 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 Film Extrusion 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 Film Extrusion be customized with our brand logo?
Yes, PHApack provides full OEM/ODM services for PHA Pellets for Film Extrusion. Customization options include custom dimensions, colors, flexographic printing up to 6 colors, private label packaging, and branded embossing.
