Biodegradable Mulch Film

Product Overview

Biodegradable mulch film is a new type of agricultural mulch film produced using biodegradable materials. Unlike traditional non-degradable plastic mulch films, it simultaneously delivers core agronomic benefits—moisture conservation, soil warming, and weed suppression—in agricultural settings. During its effective service life, it fully meets the covering needs of various crops; after use, it naturally degrades in the environment without leaving behind persistent plastic residues that are difficult to remove, thereby fundamentally preventing long-term soil contamination and adverse effects on crop growth. The product’s effective service period can be customized according to the customer’s specific planting requirements, and manufacturers offer one-on-one solution quotation services to help growers reduce labor costs associated with residual film collection and environmental remediation expenses, aligning with the eco-friendly demands of green agriculture. Based on industry standards for fully biodegradable mulch films, this product achieves a 35–40% biodegradation rate within 45 days and an 80–90% rate within 180 days, with no harmful residues left behind during degradation, making it environmentally friendly.

Core Functions

First, moisture conservation: once applied to the soil surface, the mulch film effectively reduces natural evaporation, stabilizes soil moisture, decreases irrigation frequency and water usage, and helps farmers in arid and semi-arid regions cut water consumption while improving water-use efficiency. Second, soil warming: the film allows shortwave solar radiation to pass through while blocking longwave thermal radiation from escaping, thus raising the temperature of the cultivated layer. In early spring when temperatures are low, it helps crops withstand cold damage, advances sowing and growth cycles, and boosts seedling emergence rates and early-stage vigor. Third, weed suppression: the mulch layer blocks light necessary for weed germination, inhibiting photosynthesis and growth, reducing competition between weeds and crops for soil nutrients and water, and lowering herbicide usage—aligning with green farming practices. Fourth, self-degrading with zero residue: after completing its intended service life, the product gradually breaks down into harmless substances like water and carbon dioxide under microbial action, unlike conventional plastic mulch films that persist in the soil for decades, causing residual film pollution. This fundamentally addresses issues such as disruption of soil aggregate structure, interference with root development, and reduced soil permeability and aeration.

Key Advantages

First, outstanding environmental credentials: made from biodegradable materials, it degrades naturally without leaving any residue. Compared to similar products in the industry, it demonstrates a 35–40% biodegradation rate within 45 days and up to 80–90% within 180 days, with no harmful byproducts generated during degradation, avoiding secondary pollution of soil and water bodies and fully meeting the environmental standards of green and organic agriculture. Second, comprehensive agronomic support: it simultaneously provides the three core functions of traditional mulch films—moisture retention, soil warming, and weed control—fully replacing conventional non-degradable mulch films throughout the entire growth cycle, without compromising performance due to its biodegradability. Third, flexible service life customization: the effective service period can be tailored to suit each customer’s specific planting needs, matching appropriate degradation rates to different crops’ growth cycles and regional climatic conditions, thus avoiding premature degradation that could affect planting outcomes or slow degradation requiring manual removal. Fourth, lower overall operating costs: after use, there’s no need to organize labor for collecting, recycling, or transporting residual film, significantly cutting labor expenses associated with residual film management while also eliminating the cost of soil remediation caused by residual film pollution. Over time, total investment is lower than that of traditional non-degradable mulch films. Fifth, flexible service coordination: manufacturers provide personalized solution and pricing consultations, matching the most suitable mulch film specifications and service periods to customers’ varying farm sizes and crop types, sparing them the hassle of independently determining optimal solutions.

Target Customer Base

The primary target customers include individual farmers who prioritize eco-friendly farming practices, large-scale agricultural cooperatives, agricultural production bases engaged in green and organic farming, agricultural producers located in areas prone to high levels of residual film pollution, and modern agricultural enterprises seeking low-carbon, environmentally sustainable farming outcomes. These groups commonly face challenges such as difficulties and high costs associated with collecting residual film after using traditional mulch films, as well as long-term impacts of residual film pollution on farming productivity, while maintaining stringent environmental expectations. The functionality and characteristics of biodegradable mulch films perfectly align with these customers’ practical production needs.

Application Scenarios

This product is ideally suited for covering field crops, vegetable crops, and various cash crops, particularly in agricultural areas where minimizing residual film pollution is critical. In field crop cultivation, it can meet the full-season coverage needs of corn, wheat, potatoes, and other major field crops, helping farmers reduce the workload of residual film collection. For vegetable cultivation, it supports early-spring seedling nurturing and open-field vegetable planting, boosting seedling emergence rates and accelerating early growth. In cash crop production, it covers melons, medicinal herbs, and specialty cash crops, reducing herbicide use and enhancing the green quality of these crops. In regions with frequent residual film pollution, it can gradually replace traditional non-degradable mulch films, reducing local accumulation at the source and improving soil quality.

Addressing Industry Pain Points

This product specifically tackles two major industry challenges associated with traditional mulch films: First, the issue of residual film pollution caused by the difficulty of degrading conventional mulch films. Traditional non-degradable plastic mulch films take hundreds of years to break down naturally, leaving behind vast amounts of fragmented residues that disrupt soil aggregate structure, impair soil permeability and aeration, hinder root development and nutrient transport, ultimately leading to declining soil fertility and reduced crop yields. Residual film also spreads with agricultural waste, contaminating nearby water bodies and rural environments. By contrast, this product degrades naturally without leaving any residue, effectively preventing soil degradation caused by accumulated residual film. Second, the high cost of collecting residual film after use. Traditional mulch films require significant manpower for field collection, sorting, and transportation—especially in large-scale field operations, where labor costs for residual film recovery account for a substantial portion of total farming expenses. Moreover, even after careful collection, fine residual fragments often remain in the soil, resulting in continued environmental pollution despite considerable effort. With this product, no manual collection of residual film is needed, dramatically reducing labor costs while achieving the environmental goal of zero residual film pollution.
