Self-adhesive material production technology was invented by Avery Dennison of the United States in the 1930s, and China's self-adhesive material industry was gradually developed by American Avery Dennison after it was invested in China in 1994. There is a gap of about 60 years between China and foreign developed countries. The adhesive material industry also has a huge industrial chain, including paper, chemicals, equipment, electronics and other industries. Because there is a big gap between similar industries in China and foreign countries, the domestic self-adhesive industry has huge compared with foreign developed countries. gap.
Coating equipment
The coating speed of coating equipment in developed countries in Europe and America can reach 800 to 1,000 meters per minute, and it can also be maintained at about 500 to 600 meters per minute under normal conditions, while the maximum coating speed for domestically produced equipment is generally 200 meters per minute. Some small business equipment even has speeds of tens of meters per minute, and the gap is too great.
The automation level of equipment is one of the standards for measuring equipment level. The coating equipment in foreign developed countries is basically fully automated, including the automatic detection of the coating thickness of adhesives and silicone oil, the automatic scanning and tracking of quality in the coating process, and the bottom paper. , automatic change of surface material, automatic switching, control of coating tension, equipment for non-stop production.
The faster the coating speed and the higher the level of automation, the higher the production efficiency and the more stable the quality. Therefore, domestic foreign-funded self-adhesive material plants use imported equipment, which is one of the reasons that foreign companies can capture the Chinese market.
2 bottom paper and surface material
Raw materials include bottom paper and face stock, while bottom and face stocks consist of paper and film. The quality of the raw materials directly affects the quality of the finished self-adhesive material because the adhesive material is a composite material. China is a country with a low forest coverage rate. The papermaking industry has no advantage. The production and production of the same thin film materials have no advantage due to the domestic chemical industry and resources.
The use of domestic materials for coating composite adhesive materials has a wide gap compared with imported similar materials, including material density, smoothness, color stability, and tension uniformity. At present, the surface materials of domestic high-grade self-adhesive materials are basically imported, or produced by domestic and foreign-funded enterprises. The self-adhesive materials produced by all domestic raw materials are only used for low-grade label products.
In the bottom paper, domestic production and processing companies have done a lot of work. The pulp used is mainly imported. Although the quality of finished products is different from that of imported bottom paper, as long as the quality is stable and can be applied, the medium-to-high end adhesive materials are currently used. It is basically a combination of imported surface materials and domestically produced bottom paper. The localization of the bottom paper has been solved and can meet the needs of the domestic market.
