PHA mulch films provide superior temperature control and moisture preservation. Typically designed in dark shades, they increase soil temperatures by 2–5°C, accelerating root growth and seed emergence in moderate climates.
Crop Support
Optimized for tomatoes, cucumbers, strawberries, and corn.
High Yield
Rice yields reached 10.39 t/ha, a 47.59% increase over bare soil.
PHA vs. PE Mulch Films
| Feature | PHA Mulch Film | Traditional PE Film |
|---|---|---|
| Tensile Strength | 20–40 MPa (Modified) | 30–50 MPa |
| Permeability | 1–2x Higher (Better root oxygen) | Low (High humidity retention) |
| Durability | 4–8 Months (Cross-linked) | Indefinite (Requires removal) |
| Soil Impact | Zero residue; enhances microbes | Microplastic contamination risk |
Multi-Layer & Composite Designs
PHA + PCL Dual-Layer
Combines PCL flexibility for soil contact with PHA core for structural integrity and breakdown.
Radiation Strengthening
30 kGy electron beam radiation creates films ~175 μm thick with 110% transparency.
PLA/PBAT Blends
Increases overall strength by 30–50%, reducing breakage during mechanical application.

PHA Biodegradable Mulch Film: The Ultimate Solution for Sustainable AgricultureOrganic Certification
- EN 17033: 90% breakdown in 2 years.
- ASTM D5988: CO₂-based degradation metrics.
- Eco-Friendly: Favored over petroleum-based PBAT.
Suitability for Organic Farming
PHA films fit organic practices by meeting rigorous global standards. During breakdown, PHA naturally enhances soil microbes without disrupting structure, unlike traditional polyethylene remnants.
Future Outlook
Current efforts focus on cost reductions and field validations across diverse climates to ensure reliable crop support while aligning with environmental goals.
