[0002] In our daily life, we often see packaging bags, which are used to package various supplies, so that the goods can be easily transported and stored during the production and circulation process. Usually, there are two ways to make packaging bags. One is that the packaging manufacturer uses roll film to fill on an automatic packaging machine and form and package it into various packaging bags; the other is that the bag making machine makes various packaging bags and then fills the contents. A good packaging bag design can not only promote consumer consumption, but also fully protect the safety of the internal goods. At the same time, the choice of materials and the nature of the packaging are also noticed by people.

[0003] The production process of packaging bags is a complicated process, which usually includes multiple links such as design, material preparation, printing, lamination, cutting and assembly. First of all, the shape, size and style of the packaging bags need to be determined according to customer requirements and product characteristics. After that, the produced packaging bags also need to undergo a series of tests. After a series of testing processes, they meet the production standards before they can be mass-produced. In this process, the specifications, shapes and thickness of the packaging bags need to be accurately measured, and their properties testing cannot be ignored. Some businesses usually ignore the issue of safety testing, which leads to a large number of adverse events. Summary of the invention
