Agricultural Film Mulch Black Masterbatch Blackness Granule Pellets is a premixed particle composed of black pigment and plastic matrix material (such as polyethylene, polypropylene, etc.). In the agricultural industry, black masterbatch is usually used to produce agricultural film, especially in mulching planting, to improve the product's light-shielding, UV resistance, anti-aging and other properties.
The basic ingredients of black masterbatch include:
Black pigment (usually carbon black or other black organic pigments);
Polymer matrix (such as polyethylene, polypropylene and other plastics);
Additives (such as antioxidants, UV inhibitors, etc.) to extend the product life and improve anti-aging properties.
Product functions:
Increase black appearance: mainly provide a uniform black appearance, so that the film surface has a strong light-shielding ability.
Inhibit weed growth: Black mulch can effectively prevent sunlight from reaching the soil surface, thereby inhibiting weed growth, reducing the use of pesticides, and reducing the cost of manual weeding.
Maintain soil moisture: Black mulch can reduce water evaporation, maintain soil moisture, and improve the growth environment of crops.
Increase crop yield: By controlling soil temperature and humidity, promote crop growth and achieve an increase in yield.
Anti-ultraviolet and weather resistance: Anti-ultraviolet additives are added to the mulch film to make it have strong weather resistance and long-term stability, and can adapt to different climatic conditions.
Application areas:
Agricultural planting: Black masterbatch is mainly used for mulch film production, suitable for greenhouses, open-air farmlands and other agricultural environments, especially in the cultivation of vegetables, fruit trees and other crops.
Vegetable planting: For example, tomatoes, cucumbers, peppers, etc., the use of black mulch film can effectively control weeds, keep the soil moist, and promote early maturity of crops.
Fruit tree planting: Such as grapes, apples, citrus, etc., by covering the mulch film to increase soil temperature and extend the growth cycle of fruit trees.
Agricultural greenhouses: Black masterbatch mulch film is used for greenhouse planting, especially in controlling light, temperature and humidity, which is very effective, helping to create an optimized growth environment.
Aquaculture: In some aquaculture (such as pond farming), black masterbatch mulch film can be used at the bottom of the pond to help reduce water evaporation, control water quality and inhibit the growth of aquatic plants.
Land improvement: In some areas with poor land or dry soil, using black masterbatch mulch to cover the soil can effectively retain moisture and promote soil improvement and water retention.
Gardening: In the gardening industry, black mulch is widely used in flower planting, lawn planting and other fields, which is decorative and practical.
