5+ Common additives for agricultural mulch films today

• Moisture retention and water conservation: By minimizing the direct impact of intense sunlight and wind on the soil surface, mulch films significantly reduce evaporation rates. Water is absorbed more effectively into the soil and root zones, helping to optimize irrigation usage.
• Pest and disease control: The film acts as a physical barrier, reducing the risk of infestation from harmful insects, bacteria, and microorganisms. With soil, seeds, and root systems better protected, the overall incidence of pests and diseases is lowered.
• Reduced fertilizer demand: When the soil surface is covered and stabilized, nutrients are less likely to be leached or degraded. Consequently, farmers can reduce the frequency and quantity of supplementary fertilizer applications.
• Environmental protection: Minimizing pests and maintaining soil quality reduces reliance on pesticides and chemical fertilizers. This helps control soil pollution and supports the transition toward sustainable agricultural production.

5 Common additives for agricultural mulch films today

UV-resistant additives

UV additives function to protect plastic materials from the harmful effects of ultraviolet radiation

Anti-fog additives

Fogging causes reduced visibility, making it difficult to observe and monitor crop growth. Anti-fog additives are incorporated directly into the material during the manufacturing process and function by lowering the surface tension of the plastic film, allowing moisture vapor to spread evenly into a thin layer instead of condensing into droplets.
In addition, anti-fog additives contribute to improving the overall performance of mulch films by limiting moisture penetration into the material, thereby reducing the risk of mold formation and harmful microorganisms.

Organic additives

Organic additives are a group of fillers added to conventional plastics to enhance the biodegradability of agricultural mulch films after their service life. These fillers are typically derived from natural sources such as rice straw, leaves, or sawdust, and can gradually decompose under the action of microorganisms in the soil.

Thanks to the natural decomposition mechanism, agricultural mulch films can be plowed directly into the soil after harvest without the need for collection, thereby reducing plastic waste. The decomposition of fillers also adds organic matter to the soil, helping to improve the structure and fertility of the cultivated land.

Black Carbon additives

Carbon Black additives are fine black powder pigments produced from the incomplete combustion of heavy oil or natural gas. When incorporated into agricultural mulch films, Carbon Black helps absorb UV radiation and limit plastic aging under sunlight. At the same time, this additive also acts as a reinforcing filler, enhancing mechanical strength and improving the abrasion resistance of the mulch film.

PE Filler masterbatch

PE Filler masterbatch is commonly added to agricultural mulch films to optimize material properties and improve performance under outdoor cultivation conditions. The main benefits of using this type of additives for agricultural mulch films include:

• Enhancing the mechanical stability of the film, limiting excessive elongation and reducing the risk of tearing or puncturing during installation.
• Improving surface uniformity and smoothness, allowing the film to adhere closely to the soil and increasing ground contact.
• Improving moisture retention and coverage efficiency by reducing gaps between the film and the planting bed surface.
• Optimizing production costs by reducing the amount of virgin PE resin while maintaining effective performance.
