It can be seen from Fig. 3 and Fig. 4 that the thicker the film, the lower the sensitivity of the film. When the film thickness is 11 μm, the sensitivity is 39.0 μm, and when the film thickness is 39 μm, the sensitivity is 192.4 μm.

The fabrics of the backpack are mainly PU, canvas, cotton, Oxford, cowhide, polyester, denim, PVC, etc.
The canvas backpack is very durable, even if it is scratched with a small knife, it will not break very much. However, the rucksack is a casual style and is more suitable for casual clothes.
Leather backpacks generally use cowhide, sheepskin or ostrich skin, crocodile skin and python skin, etc. The leather bag has a good texture and is very resistant to dirt, but the price will be higher.
