Agricultural film is: plastic film, plastic film and agricultural film, the main component is polyethylene, used to cover the farmland, so that the ground temperature, to maintain soil moisture, promote seed germination and rapid growth of seedlings; also inhibit weed growth The role.
The raw material of the agricultural film is usually PE polyethylene, PE polyethylene is ethylene produced by polymerization of a thermoplastic resin. Also included in the industry are copolymers of ethylene with a small amount of alpha-olefins. Polyethylene odorless, non-toxic, feel like wax, with excellent low temperature performance, chemical stability, and resistance to the majority of acid and alkali erosion. At room temperature is not soluble in the general solvent, water absorption, electrical insulation performance.
Agricultural film requirements are: moisturizing, heating, non-toxic, non-polluting, anti-aging and so strong.
Black masterbatch in the role of agricultural film in the following points:
1, fast and efficient for the agricultural film coloring.
2, to enhance the anti-aging properties of agricultural film.
3, to improve the agricultural film surface smoothness, to prevent the skin, rupture.
