1. Core Product Advantage: Completely Solving the "White Pollution" Problem

Fully biodegradable mulch films are made from bio-based materials (such as PBAT, PLA, etc.) as core raw materials. After use, they can be completely decomposed into carbon dioxide and water through microbial action, fundamentally avoiding the centuries-long soil residue problem caused by traditional PE mulch films. Compared to additive-based degradable mulch films (which only partially degrade and may produce microplastics), fully biodegradable mulch films pose no risk of secondary pollution. They comply with China's national standard "Fully Biodegradable Agricultural Ground Cover Film" (GB/T 35795-2017) and are a truly eco-friendly choice that achieves a "from farmland to nature" closed loop.

2. Intelligent Degradation Characteristics: Precision Matching of Agricultural Needs

The degradation cycle of the product can be flexibly customized (e.g., 60 days, 90 days, 120 days, etc.) according to crop growth cycles and regional climates. This ensures optimal performance in insulation, moisture retention, and weed suppression during the crop growth period, with automatic degradation after harvest, eliminating the need for manual recovery. For example, for short-term crops like peanuts and potatoes, the mulch film can rapidly disintegrate at harvest time, while for long-cycle crops like eggplants and tomatoes, it can maintain effective coverage for over 120 days, balancing agricultural needs with environmental benefits.

3. Significant Agronomic Benefits: Win-Win for Yield Improvement and Soil Enhancement

• Yield Increase and Efficiency: Experiments show that fully biodegradable mulch films can enhance soil microbial activity, improve root aeration, and increase average crop yields by 5%-15% for peanuts, sweet potatoes, and other crops.

• Labor and Cost Savings: No need to recover residual film, saving approximately 30%-50% in labor costs per acre, making it especially suitable for large-scale farming.

• Soil Health: Degradation byproducts can be converted into organic matter, alleviating soil compaction caused by traditional mulch films and improving soil fertility over long-term use.

4. Authoritative Certifications and Empirical Data: Reliable Quality Assurance

When applied in temperate and humid regions, the product not only maintains yield improvement effects comparable to traditional mulch films (averaging a 27.72% increase in crop yield) but also reduces global warming potential (GWP) by 18.27%, demonstrating significant environmental advantages. Additionally, it has obtained certifications from TÜV Rheinland and SGS test reports, with successful applications across millions of acres of farmland in 26 provinces nationwide.

5. Applicable Scenarios and Usage Recommendations

• Key Crops: Economic and staple crops such as potatoes, peanuts, corn, rice, and tobacco.

• Regional Adaptability: Particularly suitable for temperate and humid regions, as well as environmentally sensitive areas like organic farms and water source protection zones.

• Usage Tips: Store in a dry, dark place (shelf life of 8 months). Ensure the field is leveled before laying the film, and avoid direct contact with organic fertilizers to optimize degradation effects.

Choosing fully biodegradable mulch films means choosing efficient farming and a responsibility to the land. Let’s empower green agriculture with technology and protect fertile soil for future generations!
