[0006] Antibacterial layers are provided on the outer sides of the top paper layer and the bottom paper layer. By providing the reinforcement layer, the connection strength between the top paper layer and the bottom paper layer can be enhanced, and the antibacterial layers provided on the outer sides of the top paper layer and the bottom paper layer can play an antibacterial role.
[0007] Furthermore, asbestos fibers are provided in the through holes above the reinforcement layer and between adjacent ribs. Through the asbestos fibers, heat preservation and flame retardant effects can be achieved.
[0008] Furthermore, the thickness of the reinforcement layer is 0.5 - 1 cm. In practical applications, the thickness of the reinforcement layer can be selected according to needs, and all are within the protection scope of the utility model.
[0009] Furthermore, the material of the reinforcement layer is kraft paper.
[0010] Furthermore, the material of the top paper layer is corrugated paper.
[0011] Furthermore, the material of the bottom paper layer is laminated paper.
[0012] Furthermore, the antibacterial layer is bamboo fiber paper coated with activated carbon on the surface. The bamboo fiber paper coated with activated carbon on the surface can play an antibacterial role.
[0013] Compared with the prior art, the beneficial effects of the technical solution of the utility model are:
[0014] The packaging paper sheet structure disclosed by the present utility model can strengthen the connection strength between the face paper layer and the bottom paper layer through the setting of the reinforcement layer, and the antibacterial layer provided on the outer sides of the face paper layer and the bottom paper layer can play an antibacterial role.
