Abstract
This paper studied the standardization course of cement packaging bags in China since the first release of the national standard for cement packaging bags in 1988, so as to provide reference for the revision of the standard. By analyzing the revisions of the previous published national standards for cement packaging bags (GB 9774 and GB/T 9774), and the updates and improvements in standardization of bag making technology of cement packaging bags were expounded, from the aspects such as the classification of cement packaging bags, bag making material, bag type, physical and mechanical properties, applicable temperature, firmness, moisture-proof performance, etc. Through the 2018-2020 census of product quality of cement packaging bags, the necessity of standardization of cement packaging bags was expounded from the aspects of moisture-proof performance, physical and mechanical properties, changing seams to paste bottom bag, plastic prohibited order, green packaging, etc. By comparing the test methods and index requirements of moisture-proof performance in the new and old standards of cement packaging bags, this paper expounds the trend of standardization of moisture-proof performance of cement packaging bags. The degree of internationalization of cement packaging bags in China is relatively low, and the standardization work needs to be further in line with international standards to lead the development of the cement packaging industry.
