PHA Biodegradable Mulch Films:Usage Performance and Application Scenarios

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.

10–30% Improved Water Efficiency
85% Weed Suppression Rate

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 Agriculture

Organic 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.
