[0008] Preferably, the middle layer is provided on the outer surface of the kraft paper base layer, and the protective layer is provided on the outer surface of the middle layer.

[0009] Preferably, the inner wall of the inner bag is provided with a waterproof film, and an aramid fiber layer and a polypropylene fiber layer are provided between the middle layer and the protective layer.

[0010] Preferably, the inner surface of the aramid fiber layer is bonded to the outer surface of the polypropylene fiber layer, and the outer surface of the protective layer is provided with an outer film layer.

[0011] Preferably, the front end of the sealing pad is connected with a Velcro 3, and the front end of the bag body is connected with a Velcro 4 corresponding to the Velcro 3.

[0012] Preferably, a hand strap is bonded to the upper end of the outer surface of the bag body, and the number of the hand straps is two.

[0013] The beneficial effects of the utility model are as follows: through the design of the inner bag, liquid leakage can be avoided. At the same time, the inner bag and the bag body are connected by thorny Velcro, which makes it convenient to disassemble the inner bag and clean it. The design of the protective film makes the bag body have good waterproofness and strength, and forms good waterproof, wear-resistant and strength protection on the outer surface of the bag body.
