High-intensity corrugated packaging box made of paper instead of wood

Abstract

The invention discloses a high-intensity corrugated packaging box made of paper instead of wood, which comprises a bottom paper board, a left paper board, a front paper board, a right paper board and a rear paper board, wherein the left paper board, the front paper board, the right paper board and the rear paper board are respectively connected to the corresponding edges of the bottom paper board; the left paper board, the front paper board, the right paper board and the rear paper board are folded upwards to be surrounded into a storage space; one side of the left paper board is connected with a left reinforcing plate which can be folded and attached to the inner surface of the left paper board; one side of the front paper board is connected with a front reinforcing plate which can be folded and attached to the inner surface of the front paper board; one side of the right paper board is connected with a right reinforcing plate which can be folded and attached to the inner surface of the right paper board; one side of the rear paper board is connected with a rear reinforcing plate which can be folded and attached to the inner surface of the rear paper board; the lower end of each reinforcing plate is pressed against the upper end face of the bottom paper board. Reinforcing structures are additionally arranged in the packaging box, so that bearing and compressive strength of the packaging box is promoted, and articles packaged in the packaging box can be effectively protected without using a wood frame.

Description

Technical field [0001] The invention relates to the technical field of product packaging boxes, in particular to a high-strength corrugated packaging box with paper instead of wood, which has high strength and can replace existing cartons. Background technique [0002] In the prior art, in the packaging and transportation of valuables or heavier products, the valuables or heavier products are packaged in carton in advance, but the existing carton is made of single-layer cardboard, and its compressive strength and resistance The impact strength is relatively poor; in order to solve the problem of the accumulation of carton stacks during transportation, which is likely to cause the carton to deform and damage the contents, a packaging frame made of wood is added to the carton, and the packaging is made of wood. The frame bears the gravitational pressure and protects the carton. Although the carton is prevented from being deformed under pressure and the contents are damaged, it need...

Problems solved by technology

[0002] In the prior art, in the packaging and transportation of valuables or heavy products, the valuables or heavy products are packed in cartons in advance, but the existing cartons are made of single-layer cardboard, and their compressive strength, anti- The impact strength is relatively poor; in order to solve the problem that the cartons are piled up during transportation, which may easily cause deformation of the carton and damage the items in it, a packaging frame made of wood is added outside the carton. The frame bears the gravity pressure and protects the carton. Although it avoids the deformation of the carton and the damage of the items in it, it needs to use a lot of wood, which causes waste. At the same time, it is cumbersome to operate. Items are packaged, and wooden frames need to be made, and the packaging efficiency is low, which also increases the labor and input costs of the enterprise.
