⒈Light box cloth:
The light box cloth is a kind of light box sign fabric composed of two layers of pvc and a layer of high-strength grid cloth, which is divided into two types: internal lighting and external lighting. The main production methods include knife coating method, calendering method, and pasting method (melting method).
Key points for quality identification of light box cloth: thickness, tensile strength, ductility, weather resistance, light transmittance, flame retardancy, peeling degree, flatness, such as ink absorption, color reproduction, etc.
⒉The background of advertising products-----light box cloth
The light box cloth is a combination of pvc material and mesh light guide fiber. It has the characteristics of good flexibility, uniform light transmission, convenient division, splicing, consignment, and simple outdoor installation. It is especially suitable for color printing. According to the requirements of outdoor use, the light box cloth can achieve the effects of waterproof, mildew resistance, flame retardant, cold and heat resistance, and UV resistance. Because the light box cloth has strong typhoon resistance, it is especially suitable for making large outdoor advertising signs. At present, 95% of the large color inkjet light box screens in the Chinese market use light box cloth as the substrate.

According to the light transmittance and the position of the light source, the light box cloth is divided into three types: rear light light box cloth, front light light box cloth and grid cloth.
Post-lighting light box cloth is used to make post-light source light boxes, and its light transmittance is generally between 25-35%. Such light boxes are mostly medium and small, and are mostly used to make roadside light boxes, store door light boxes and indoor publicity light boxes. Generally, the area is small, no more than 100 square meters.
The front lighting light box cloth is used to make the front light source light box, and its light transmittance is generally between 5-10%. Because this kind of light box cloth is more resistant to typhoons, it is often used to make large outdoor light boxes, such as building billboards, highway side light boxes, and urban Optimus Prime light boxes. At present, large-scale outdoor light boxes between 100 square meters and 400 square meters in China mostly use this kind of light cloth.
The grid cloth is designed and made according to typhoon climate areas such as Taiwan and Fujian. Because the surface of this kind of material is densely arranged with many meshes, which can make the wind pass through the surface of the light cloth, it can greatly reduce the pressure of the typhoon on the light box and make the picture more Long-term outdoor use effect. Because of this feature, grid cloth is mostly used to make super-large signage advertisements and architectural advertisements. The Coca-Cola Company used this type of light cloth to successfully produce a screen of more than 8,000 square meters in Shanghai, while the Germans created an "aspirin" advertisement with a total area of ​​more than 20,000 square meters, which also used such materials.
