Edit:Qingzhou Luyi Plastic FactoryUpDate:2018-11-10

The common black and white film material on the market is generally PET, which is divided into black and white, one side is white, the surface is reflective, the other side is black matte, not reflective, and some black and white films can also be made into black reflective surface. The optical product has good shading effect, and the white surface has a reflectance of more than 88% and a good reflectance. The black and white film is coated with a black coating on one of the surfaces and a white high density PET film. The number of coatings is usually 8-12 times and the thickness is 0.003 mm. Depending on the density of the coating. When the white PET is painted black, the coated surface becomes black, and the other side without the coating is still white, so it is called black and white film.
The black and white film is mainly used in the backlight combination of LCD and LED display, such as display components of notebook computers, mobile phones, PDAs, LEDs, LCDs, etc., and the backlight frame is fixed and shielded. The black and white film features black shading and good white surface reflection. It has the advantages of moisture resistance, UV resistance and good shading ability. It has moderate viscosity and no residual glue after tearing. The main purpose is to block and connect.
If it is made into a black-and-white phase film, it can not only have the heat preservation and moisturizing effect of the ordinary white film. It also has the effect of preventing weed growth and regulating the ground temperature. Early spring crops are planted in the transparent membrane to facilitate the warming of the seedlings. Later, the roots extend to the black membrane and stabilize the root temperature to reduce the high temperature effect. The autumn crops are planted in the black membrane to reduce the effect of early autumn high temperature on the seedlings. The transparent film can also facilitate the growth of the root temperature of mature plants.
In order to keep up with the market, Qingzhou Luyi Plastic Factory has produced a variety of black and white films, which can also be customized according to customer needs. Welcome customers who need it to call or come to the factory to order.
