Due to self-reliance bag packaging good market effect, and self-reliance bag packaging products emerge in endlessly, committed to the research and development production enterprise more and more of this filling machine. Companies mainly rely on their own experience, in the absorption on the basis of introduction of foreign advanced technology, according to the characteristics of domestic research and development of independent innovation, make the products with special features and occupy a certain market share. The perfect standard system helps to improve the level of product quality and product class, standardize market order. But, at present the self-supporting bag filling screw cover packing machine there is no perfect country or industry standards of products. According to the standard system revision plan, formulated by the national packaging machinery standardization technical committee is responsible for organizing the self-supporting bag filling screw cap packaging machine industry standards. This standard has been released in China's packaging standard network industry surveys, relevant enterprises can login website to put forward proposals and Suggestions for the establishment of standards, promote to develop to meet the requirements of industry development, and guide the healthy development of the industry industry standards. We are looking forward to self-supporting bag filling screw cover packaging machine standard come on stage, speed up the implementation of this kind of equipment seriation, standardization, generalization, make its rapid development on the basis of sound strong.
