Corrugated carton and preparation method thereof

Abstract

The invention discloses a corrugated carton and a preparation method thereof, and belongs to the field of cartons. The corrugated carton comprises a carton body composed of corrugated boards, and eachcorrugated board comprises outer transparent waterproof paper, corrugated paper and inner transparent waterproof paper which are arranged in sequence from outside to inside, wherein a moisture-sensitive color-changing film formed by a moisture-sensitive color-changing composite reagent is arranged between the outer transparent waterproof paper and the inner transparent waterproof paper. The moisture-sensitive color-changing film is formed on the corrugated paper in a spray film-forming manner; whether water enters the carton or not can be found in time, a worker can conduct treatment in time,and caused commodity losses are reduced; and meanwhile, the humidity of the corrugated paper and the maximum bearing capacity of the carton body under the humidity can be known through the color shown by the moisture-sensitive color-changing film, the weight of commodities in the carton body can be strictly controlled, damage of excessive bearing to the carton body in the using process is reduced, and the commodity losses are reduced to the maximum degree.

Description

Technical field [0001] The invention relates to the field of paper boxes, and more specifically, to a corrugated paper box and a preparation method thereof. Background technique [0002] Corrugated box is one of the most widely used packaging products, and the amount used has always been the first of various packaging products. Corrugated boxes have gradually replaced wooden boxes and other transport packaging containers with their superior performance and good processing properties, and have become the main force of transport packaging. In addition to protecting commodities, facilitating storage and transportation, it also plays a role in beautifying and promoting commodities. Corrugated boxes are environmentally friendly products, which are good for environmental protection and convenient for loading, unloading and transportation. Corrugated boxes are made of corrugated cardboard after die cutting, creasing, nailing or gluing. Corrugated cardboard is a multi-layer glued body...

AI Technical Summary

Problems solved by technology

[0004] The corrugated cartons used for packaging and transportation have their maximum load-bearing strength. Generally, the weight of the packaged goods should not exceed its maximum load-bearing strength. Otherwise, the carton will not be able to bear the load and cause damage or rupture, resulting in damage to the goods. After that, the compressive strength will decrease, and its maximum load-bearing strength will also decrease accordingly.

[0005] When the existing corrugated boxes are in use, it is often not found in time whether the cartons are flooded, so that the cartons cannot bear the weight of the goods during use and are broken and damaged, resulting in the drop or loss of the goods; and when water is found in the cartons, in order To protect the goods inside, we usually choose to replace the cartons, and recycle the cartons after water ingress, which will increase the workload and easily cause waste of carton materials
