Dry test compound plastic flexible packaging raw materials have what advantages

　　In the production and manufacturing mode of compound plastic flexible packaging raw materials, the more common is dry compound, extrusion compound and co-extrusion compound. In addition, the active solvent coating compound, sizing compound, evaporation compound, thermal sol compound is also the production of compound plastic flexible packaging raw materials are more common way.

　　Dry compound is a more common production and manufacturing method used in the production and manufacturing of compound plastic flexible packaging raw materials in China. The advantages of this method are as follows:

　　① Wide adaptability. Can be used in the production and manufacturing of a variety of composite plastic flexible packaging raw materials, both can be used in a variety of plastic film between the composite, but also can be used in plastic film and other film raw materials (such as paper, aluminum platinum, plastic film containing inorganic coating plate) composite.

　　(2) Perfect processing technology, good applicability. Dry compound used in China to use for a long time, production line equipment and auxiliary equipment (dry cut machine, printing equipment, surface flame processing machinery and equipment, plastic bag making machine, etc.), common raw material purchasing (with a plastic film composite plate, aluminum foil, printing paper, ink printing, adhesive, etc.) are manufacturing supply company.

　　The sales market is perfect and widely used. After more than 30 years of production and manufacturing in China, dry compound has developed a perfect sales market in China; Dry compound commodities have been widely used in various fields such as national defense and security, scientific research, industrial and agricultural production and manufacturing.

　　As an industrial production and processing technology, dry compound also has many shortcomings, the key has the following two points:

　　(1) The dry compound takes membranous materials (semi-production and processing commodities) as raw materials, and the energy consumption is high in the production process. The dry compound commodities have the problem of high cost.

　　② Dry compound selection of solution type adhesives, there are many shortcomings, such as flammability, inflammable and explosive, environmental protection adaptability is weak, negligence is also likely to cause residual organic solvents in the commodity over standard, environmental health characteristics are not high problems.
