Mounting machine special glue the earliest use of mostly derived from natural substances, such as starch, dextrin, gelatin, bone glue etc.. Only with water as solvent, heated and compounded into rubber, because of its single component, poor applicability. It is difficult to meet various use requirements. With the synthetic polymer compound present, people have developed a special synthetic resin glue laminating card machine. For all kinds of adhesive occasions. In recent years, with the development of raising the level of information, a variety of modified resin come out, making the performance of special synthetic resin adhesive mounting card machine to further improve the. Many classification methods of special laminating card machine glue, according to the application methods can be divided into thermosetting, hot melt, room temperature curing, the pressure-sensitive type; according to the application object is divided into structural type and no configuration or special glue; connection form can be divided into water soluble, water emulsion, solvent type and a variety of solid type etc.. The rapid development of the world industrialization continue to move forward, from time to time almost led the entire industry chain. Laminating card special rubber industry as an independent industry, at the same time as a special auxiliary industrial packaging industry, development status and future direction of development, has become the focus of attention.

Laminating card special rubber industry is the rapid development of ultra conventional speed

The new products are increasingly developed and related high-tech appeared from time to time to fill current gaps, since the last century since the 50's. At the same time, also promoted the industry's development constantly moving, derive more and more broad application area and into a more professional refining industry.
