PHA Biodegradable Mulch Film — Soil Biodegradable Agricultural Film
Agricultural mulch film extruded from 100% PHA, designed to be tilled into the soil at the end of the growing season instead of being stripped, collected, and landfilled. Conventional PE mulch leaves fragments in the field for decades and costs growers significant labor and disposal fees to remove; oxo-degradable film simply breaks into smaller plastic pieces faster. PHA film is consumed by soil microorganisms, returning carbon to the soil with no microplastic residue, while still delivering the agronomic functions growers need: soil temperature control, moisture retention, and weed suppression.
Key Benefits
- Soil biodegradable — till into the ground after harvest, no removal labor
- Eliminates film collection, transport, and landfill disposal cost
- No microplastic residue; soil microorganisms fully mineralize the film
- Tunable degradation timeline matched to specific crop cycles

Frequently Asked Questions About PHA Biodegradable Mulch Film
What is PHA Biodegradable Mulch Film made of?
PHA Biodegradable Mulch Film 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 Biodegradable Mulch Film take to biodegrade?
PHA Biodegradable Mulch Film biodegrades completely within Tunable 6-24 months to match crop cycle. 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 Biodegradable Mulch Film hold?
PHA Biodegradable Mulch Film holds OK biodegradable SOIL, OK biodegradable MARINE, EN 17033, ASTM D6400. 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 Biodegradable Mulch Film is 500 kg. Lead time is typically 15-25 days 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 Biodegradable Mulch Film be customized with our brand logo?
Yes, PHApack provides full OEM/ODM services for PHA Biodegradable Mulch Film. Customization options include custom dimensions, colors, flexographic printing up to 6 colors, private label packaging, and branded embossing. Our R&D team can also develop custom PHA formulations tailored to your specific application requirements, including MFI optimization and additive packages.
