Agricultural film: film, plastic film and agricultural mulch film, main component is polyethylene, for covering farmland and make the temperature rise, preserving soil moisture, promote the seed germination and seedling growth. And inhibit the growth of weeds. The raw material of the agricultural land membrane is usually PE, PE, and it is a kind of thermoplastic resin which is prepared by the polymerization of ethylene. In the industry, it also includes a copolymer of ethylene and a small amount of alpha olefin. Polyethylene no odor, non-toxic, it feels like wax, has excellent low temperature resistance, good chemical stability and the ability of most acid-base erosion. Under normal temperature, the water absorption is small, and the electric insulation performance is good. The requirements of agricultural land film are: moisture, heating, non-toxic, non pollution, strong resistance to aging, etc..

The role of black masterbatch in farmland in the film has a few:

1, fast and efficient for the farmland film coloring.

2, enhance the anti aging properties of agricultural land film.

3, improve the agricultural film surface smoothness, to prevent the skin, rupture.
