Third, pressure sensitive adhesive and pressure sensitive adhesive tape
The production and application of pressure-sensitive adhesives and pressure-sensitive adhesive tapes have also seen considerable development in recent years. In 1996, China's market sales of tapes reached 2.26 billion m2, most of which were packaging tapes (2 billion m2). After entering the 1990s, the production technology of domestic pressure-sensitive adhesives gradually developed toward the direction of comprehensiveness. The United States, Japan, and other countries have successively established wholly-owned or joint ventures in China, which has, to some extent, promoted the technical level of China's pressure sensitive adhesive products. improve. For example, in the production of double-sided adhesive tapes, it has been possible to use acrylate soft monomer solution copolymer resins and various cross-linking agents to obtain pressure-sensitive adhesives and products with excellent properties in the form of diplomatic links; Pressure-sensitive adhesive products and radiation-curable pressure-sensitive adhesives also draw on foreign advanced technologies and have now been produced by a number of companies.
In the development and production of high-performance special pressure-sensitive adhesives in China, such as automotive high-strength protective tapes, strong adhesion adhesive tapes for lifting, and high-temperature and high-insulation special tapes, etc., further research is needed and needs improvement.
In addition to the above types of adhesives, China's other packaging adhesives such as labels, paper plastic sealing glue, cigarette glue, paper tube glue also with the development of various production technology requirements, continue to update.
Although China's packaging adhesives have achieved remarkable development in the past decade, there are still some gaps between them and the world's advanced level in many aspects. The major ones are: varieties and quality can not fully meet the requirements, many varieties still need to be imported; application technology research can not keep up The requirements for the development of new varieties, backward production equipment, and low level of repeated varieties are still many. At present, there are no systematic national, industrial materials and testing methods.
