The membrane panel uses three kinds of membrane materials, according to the introduction, it is suitable for making the membrane material, according to its kind, ordinary PC, PVC, pet three, according to its surface state and sand surface (translucent 3 film) and smooth surface (transparent film) point. The physical chemistry has excellent properties, and its inks are widely used as a common material for thin film switch panel layers. Prestressed concrete materials differ from sand surfaces and smooth surfaces. The reason for choosing the sand surface material is that the use of the thin film switch is mostly electronic, and the panel as the control system does not want to be disturbed by the light. The sand surface only has diffuse reflection and will not produce bright reflection, at the same time, due to the disorder of the sand surface, it has the function of hiding scratches, on the contrary, the smooth surface material does not have the above characteristics. But as a matte material, once printed on the back, the color will be bright and eye-catching, and in need of strong decorative requirements and do not need regular contact, often choose matte material to make the panel, or because of the special needs of certain display areas, for Liquid Crystal Display, the choice of matte materials is advantageous.

The price of this thin film material is very low, about half of that of PC material. If we choose polyvinyl chloride materials, we can reduce the cost of production. At the same time, PVC material has good ductility, can be cold-pressed processing. Smooth polyvinyl chloride are generally over 0.5 mm thick and are protected on both sides by pet paper or gummed paper. Most of them are used for decorative panels, while polyvinyl chloride are usually less than 0.3 mm thick and are usually provided with fixed length paper without rolls. The surface state of the film, are generally smooth transparent film, in a few cases also have sand products such as Japanese wood products, but the sand surface is very thin, similar to a non-bright surface layer, in the pet surface and get a non-bright surface, unlike PC, it is not rolled through a sand surface during mechanical calendering, which means its surface is not as obvious as PC.
