With the progress of science and technology, a variety of new products and new packaging equipment are emerging, fast moving consumer goods firms constantly improve the production concentration and the degree of automation, packaging equipment is large, fast, efficient, automated way. Therefore, as a packing material production enterprises must keep up with new trends, continue to provide customers with flexibility, production efficiency in materials. For example, in some heat-sensitive products such as chocolate, ice cream packaging, fast sealing the packaging material is gradually replacing the traditional hot-pressing sealing packaging materials. Former is different, with a special glue instead of local heat sealing layer coating on the surface of the substrate, and then squeezing at room temperature seal. Time due to reduced heat transfer, speed is greatly improved. Under normal circumstances, its speed is 8~10 times as hot sealing material, but also eliminates the odor of heated material may cause. Because it is a topical coating, and significant material savings.
