1. The material of the computer bag

Computer bags are mainly to protect computers and other electrical appliances, so the choice of materials should not be sloppy. Generally, high-density nylon or polyester materials are selected, especially polyester materials will be functionally processed, such as waterproof and wear-resistant functions.

2. The inside of the computer bag

The inside of the computer bag lies in the choice of lining and the craftsmanship of sewing. A good lining is based on density (D). The higher the density, the better the gravity and the pulling ability. Generally, 150D lining is used as the minimum standard. And his sewing process generally needs to go back and forth at least twice to strengthen the inner structure.
