Compared with ordinary bags, this design can reduce the shaking of items inside the bag and enhance the stability of the packaging.

The product is made of high - quality PE materials, which have good flexibility. Its chemical properties are stable, and it has corrosion - resistance and anti - permeability to most common substances, effectively protecting the items inside the bag from the external environment. The bag has a high transparency, allowing users to directly observe the items inside without opening the bag repeatedly, thus improving the convenience of use.
