Sealing tape, also known as BOPP tape, packaging tape, etc., is based on BOPP biaxially oriented polypropylene film as substrate, and then evenly coated with pressure sensitive adhesive emulsion through heating, making it form a glue layer of 8 micron m----28 m, forming BOPP tape master coil. It is an indispensable product in light industry enterprises, companies and individuals. There is no perfect standard in the tape industry. Only one industry standard sealer uses BOPP pressure sensitive adhesive tape to treat the original BOPP film with high voltage corona. The surface of the original film is rough, and then the glue is coated on it. First, the master film of the tape is formed, and then it is sliced into small rolls with different specifications by slitting machine. That is the daily use of the adhesive. Yes. The main component of pressure-sensitive adhesive emulsion is butyl ester. At present, there are more than 1500 adhesives manufacturing enterprises in China, with more than 3000 kinds of adhesives. It has become one of the fastest growing industries in the field of chemical industry in China.
With the development of economy and science and technology, synthetic adhesives have attracted more and more attention and become a promising industry. In China, large-scale production began in 1958 when BOPP semi-finished products were opened. In the 1980s, the development of adhesives reached a climax. However, the synthetic adhesives industry in developed countries has entered a highly developed stage. In the 1990s, the average growth rate was about 3%, and the average growth rate in China was 19.5%. In 1998, global sales of synthetic adhesives amounted to about 25 billion US dollars, of which the United States accounted for about 35% of global sales, Western Europe 25%, Japan 15%, and China only 7%. The global consumption structure of synthetic adhesives is 35% in packaging industry, 25% in construction industry, 20% in wood processing industry, 10% in automobile transportation industry and 10% in other industries.
