The application of light box cloth is the most common in the advertising industry. What types of light box cloths are common to us? Light box cloth manufacturers usually classify the light box cloth according to the production process, the light transmittance and the position of the light source, specifically:
1. Light box cloth is divided into three types according to the production process: knife-scraping light box cloth, calendering light box cloth and pasting legal light box cloth:
1, knife scraping light box cloth
The knife-scraping light box cloth process is to evenly coat the front and back sides of the base fabric with a number of anti-squeegee blades with liquid PVC slurry, and then make it completely integrated into a whole through a drying process, and then cool and shape. It is characterized by strong anti-permeability, tensile strength and anti-peeling ability. Because the product of the knife scraping method is a whole, the peeling phenomenon can be eliminated, and the strength of the joint can be greater than the product itself through welding. At present, the light box fabric width of this technology can reach 5m. Due to the complicated production process and the relatively expensive production equipment, such products are mainly imported in the Chinese market, and the price is relatively high. The most representative ones are ULTRALON made in Germany, UNIFLEX made in Korea and SIOEN made in Belgium.
2, calendering method light box cloth
The calendering method is to fully stir PVC powder and liquid plasticizers and other raw materials, and then bond with the base fabric into a whole under the pressure of a high-temperature hot roller. Its characteristic is that the surface is smooth, and the light transmission is even, and it has advantages on the inner lighting lamp cloth. However, due to the limitation of the equipment, the width generally does not exceed 3m. Both the 645 and 945 light box fabrics developed by South Korea's 3M company are produced using this process; the Lexi light box fabric developed by South Korea's LG company is also a representative of this type of process.
3, paste legal light box cloth
The pasting of the legal light box cloth is to form the upper and lower layers of the PVC film, which are heated and bonded with the light guide fiber net in the middle under the pressure of the heat roller, and then cooled to form. The biggest feature of this process is its excellent inkjet ink absorption and strong color expression. Therefore, with the rise of the large-scale inkjet industry, this type of light box cloth has also brought infinite vitality. At present, the market share of this kind of light box cloth in China has exceeded 50%. Because different types of machine nozzles have different principles.
2. According to the light transmittance and the position of the light source, it can be divided into three types: front lighting light box cloth, rear lighting light box cloth and grid cloth:
1. Front lighting light box cloth: used to make front light source light boxes, the light transmittance is generally between 5%-10%. This type of light box cloth is more resistant to typhoons, so it is mostly used to make large outdoor light boxes.
2. Rear lighting light box cloth: used to make rear light source light boxes, the light transmittance is generally between 25%-35%. Such light boxes are mostly medium and small, and are mostly used to make roadside light boxes.
3. Mesh cloth: It is designed and made according to the typhoon climate areas such as Taiwan and Fujian. Because this kind of material is densely arranged with many meshes, it can make the wind pass through the surface of the light cloth, so it can greatly reduce the pressure of the typhoon on the light box. Make the picture achieve longer outdoor use effect.
