In the 2020s, with the development of society, the sales volume of backpacks has also gradually increased, leading to the emergence of large and small backpack manufacturers in the backpack industry, all of which aim to share a share of the pie. Some manufacturers have only a few high-speed vehicles and flat vehicles, some manufacturers even have only a dozen employees, and some manufacturers lack testing equipment when producing backpacks. So, what kind of manufacturers have backpack testing equipment?

In fact, there are no more manufacturers with testing equipment than powerful manufacturers. In a group of cases, the experimental equipment owned by powerful manufacturers is as follows:

1. Load test

The backpack manufacturer conducts a load test on the backpack, the purpose of which is to clarify the load-bearing capacity of the backpack and whether it reaches the expected goal.

2. Constant temperature and humidity test

Mainly test the temperature and humidity cycle changes of backpack materials, and the adaptability of storage and use under hot and humid environmental conditions where condensation occurs on the surface of the product.

3. Zipper test

The backpack manufacturer fixes the zipper teeth on the testing machine and fixes the slider on the testing machine (pull up and down). At this time, the strength of the zipper teeth and the slider can be measured.

4. Tear strength test

Test the tear strength of backpack materials. Put the backpack material at a certain temperature and stretch it at a constant speed until it breaks.
