The black and white film material is PET, the black color is symmetrical, the surface is bright and smooth, and does not fade, the product is black and white on both sides, one side is milky smooth and easy to use, the other side is black matte, does not return light (can also be made into black return surface) for electronic optical goods production and manufacturing of light blocking actual effect is excellent, the transmission rate of white flour can be 0.88 above, Has very good reflective surface practical effect.

With the change of product varieties in the agricultural mulch manufacturing industry, the film slowly entered the sales market, and the share of the original agricultural mulch production increased from 0.02 to 0.05. At present, PO film is a prosperous commodity in recent years, although the price value is high, but the product quality is good and long life, and the application cost of farmers is of course reduced, resulting in more and more trust from farmers. The raw material of PO film is mainly metallocene, and its cost is low. Therefore, the profit is relatively rich and colorful, attracting more and more manufacturers to care about and manufacture. And the black and white film transmittance is good, the surface is not easy to blot, easy to clean.

Plastic film surface selection of organic chemistry research and development of unique polyester raw materials, the surface is not easy to absorb dust, not easy to stain, the surface after the precipitation cleaning is clean and can maintain long-term stable light transmittance, so that the plant photosynthesis ability is strong, the main stem growth is good, high production.

Using the new technology nanotechnology layer technology, the absorbent organic compounds are coated on the basic raw materials of sowing and grinding, and the interaction force between the gold nanoparticles produces a very strong film, which has a long-term stable water absorption, flow drop, anti-fog delay time for many years, and long-term anti-fog performance. Reasonably reduce the environmental humidity of the greenhouse film, and create an excellent natural environment for crop success.

Black and white film with a high density of opalescent PET film (thickness 0.025 ~ 0.mm can be selected), it is on one side, the surface is coated with black nanomaterial grade coating, the coating frequency is generally 8 ~ 12 times, thickness >0.002mm. Depends on the relative density of architectural coatings.
