On the basis of the HACCP safety management system standard, the International Organization for Standardization (ISO) developed the ISO 22000 standard — "Food (packaging) safety management system — requirements for any organization in the food chain". The standard was jointly formulated by experts from the food industry, specialized institutions and representatives of the Codex Alimentarius Commission, as well as bodies jointly established by the UN Food and Agriculture Organization and the World Health Organization.

With the rapid development of China's packaging and printing industry, unified technical standards are badly needed to standardize production, quality and testing methods in the relevant fields. These three industry standards were formally established as projects in 2007, and after repeated discussions, test verification and extensive solicitation by the expert drafting group

Making paper carrier bags by pasting is an ancient handicraft. Yet in post-press processing, while most printers know something about book binding or carton creasing and gluing, they may be far less familiar with the production process for paper carrier bags. Paper carrier bags fall broadly into two categories: ordinary packaging bags and fine shopping bags. Ordinary packaging bags are produced in a continuous run on a rotary printing bag-making machine. Their advantage is fast production efficiency, while their drawback is that the bags are rough and unrefined, so
