Transitioning from conventional Polyethylene (PE) to eco-friendly alternatives remains a hurdle for many large-scale agricultural operations. While PE offers unmatched durability, its environmental cost is no longer viable.
Thermoplastic Starch (TPS) has emerged as the most cost-effective candidate. However, a "green" label is insufficient; the film must match PE in agronomic functionality to ensure sustainability never comes at the expense of harvest volume.
Structural Integrity Guaranteed
Engineered to withstand mechanical installation and environmental stress.
Mechanical Integrity: The Ticket to Entry
The Durability Metric
High Tensile Strength and Elongation at Break ensure the film stretches across soil beds without snapping under tractor tension.
TPS-PBAT Synergy
Pure starch is brittle. We blend high-purity TPS with flexible PBAT to create a molecular matrix providing stiffness and elasticity.
Field Resilience
Superior Tear Resistance prevents localized punctures from wind shear or soil irregularities from propagating into ruptures.
Microclimate Control & Barrier Properties
Weed Suppression (Opacity %)
Our black TPS-integrated films achieve over 90% opacity, effectively starving weeds of photosynthetically active radiation.
Hydraulic Management
Hydrophobic modification controls the Water Vapor Transmission Rate (WVTR), ensuring optimal soil moisture retention in arid conditions.
Thermal Regulation
Stabilizing soil temperature during diurnal cycles is essential for germination. TPS films provide insulation against cold snaps.
Controlled Degradation Kinetics
"Degradation on Demand"
The technical superiority of a mulch film is defined by its induction period. We focus on a model that ensures crop safety before bio-assimilation.
- Induction (60–90 Days): Intact for the most vulnerable stages.
- Disappearance Phase: Rapid microbial metabolism into CO₂ and H₂O.
- Zero Microplastics: Full bio-assimilation into the tilled soil.

Technical Optimization
Finding the "Sweet Spot" in TPS content to balance cost and performance for your specific crop cycle.
| Formulation Type | Best For | Key Feature | Cost Efficiency |
|---|---|---|---|
| High TPS Content | Short-cycle vegetables (Lettuce, Spinach) | Rapid degradation, Ultra-low cost | Excellent |
| Mid-to-Low TPS (High PBAT) | Industrial Field Crops (Maize, Cotton) | PE-like performance, Long induction | Moderate |

Agronomic Validation: Yield and Soil Health
Comparable Yields
In maize and potato trials, crops under TPS mulch showed performance on par with traditional PE due to the enhanced breathability of the soil-film interface.
Rhizosphere Support
Our TPS degrades into organic components, supporting microbial diversity and securing the long-term productivity of the acreage without microplastic residues.
