The technical scheme of the utility model is that: a multilayer high-strength carton comprises an outer layer carton, wherein reinforcing blocks are fixed on the inner sides of four corners of the outer layer carton through carton nails, an inner layer carton is arranged in the outer layer carton, a buffer layer is arranged between the outer layer carton and the inner layer carton, the top ends and the bottom ends of the outer layer carton and the inner layer carton are respectively provided with an opening, the openings of the top ends and the bottom ends of the outer layer carton are respectively buckled with an upper cover and a lower cover, water-absorbent resin is arranged on the inner sides of the upper cover and the lower cover, an upper top plate is arranged on the outer side of the upper surface of the upper cover, a lower top plate is arranged on the outer side of the lower surface of the lower cover, a plurality of upper transverse through holes are arranged on the upper top plate from front to back, a plurality of lower transverse through holes corresponding to the upper transverse through holes are arranged on the lower top plate from front to back, one end of a bandage sequentially penetrates through the lower transverse through holes, the upper transverse through holes corresponding to the lower transverse through holes and is fixed with the other end of the bandage, every cardboard of outer layer face carton, every cardboard structure of interior aspect carton the same, a cardboard of outer layer face carton including being equipped with first corrugated paper, a plurality of enhancement post and second corrugated sheet from outside to inside in proper order, a plurality of the enhancement post establish perpendicularly between first corrugated paper, second corrugated sheet.

Furthermore, the buffer layer is polystyrene foam, and the buffer layer four corners has the chamfer the same with the reinforcement piece size, and the buffer layer passes through the glue bonding between outer aspect carton, interior aspect carton.

Furthermore, the periphery of the inner side of the inner layer face carton is provided with a waterproof film.

Further, the outer surface of the outer layer face carton is coated with waterproof paint.

Furthermore, the upper cover, the lower cover and the reinforcing block are all made of plastic, the inner diameter of the upper cover and the inner diameter of the lower cover are larger than the outer diameter of the outer layer face carton, and whether glue is used for fixing the upper cover and the lower cover or not is determined according to actual use conditions.

Furthermore, the water-absorbent resin is adhered to the inner sides of the upper cover and the lower cover through glue, and the size of the water-absorbent resin is smaller than the inner diameter of the inner layer face carton.

The utility model has the advantages and positive effects that: the outer layer face paper box, the inner layer face paper box and the buffer layer are arranged, so that the strength and the pressure resistance of the paper box are improved; the box body can be opened from two directions by the upper cover and the lower cover, so that the operation is convenient; the moisture-proof performance of the water-absorbing resin is improved, and the articles in the carton are protected.
