[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] In the utility model, the waterproof layer and the annular base are provided, and the surface of the entire paper tray is waterproofed by the waterproof layer, so as to form a first layer of waterproof effect, and the paper tray can be isolated from the desktop under the action of the annular base, so as to prevent moisture on the desktop from contacting the paper tray when the paper tray is placed on the desktop, and to avoid friction between the paper tray itself and the desktop when the paper tray is moved on the desktop, so as to prevent the waterproof layer on the paper tray from being excessively worn and affecting its anti-penetration effect;

[0016] In the utility model, a reinforcement layer made of high-temperature resistant and degradable material can be formed on the surface of the paper plate by arranging the reinforcement pad, shaping layer, reinforcement ring and bending part. On the one hand, a second layer of waterproof effect is formed to improve the anti-penetration performance of the entire paper plate. On the other hand, the paper plate pressed by the plate rolling machine can be reinforced, especially the bending part of the paper plate, to improve the strength of the entire paper plate and avoid the problem of the paper plate being crushed after a certain amount of things are contained.
