What kind of material is made to distinguish shading: there are two types of production and market sales of shading material, is a kind of high density polyethylene in petrochemical production, another is made with recycled net or plastic products. It is understood that the recycled material production net not only finish low, feel hard, with a pungent odor, and short service life, most of them only for one year. High density polyethylene net anti-aging, durable, the service life can reach 4 years.
According to the weight to buy shade carefully: now there are two ways: one is the market sales net according to the area, one is by weight. Farmers in the selection, don't rely on a way to buy, should carefully compare, see materials in terms of density, to prevent illegal dealers selling inferior "weight" net.
