Description

technical field [0001] The invention relates to a packaging product, in particular to a carton and a manufacturing method thereof. Background technique [0002] Packaging cartons made of corrugated cardboard have incomparable advantages over cartons made of other materials (such as wood or metal) in terms of cost savings, item protection, environmental protection, compression resistance and load-bearing performance. At present, the bottom design of the cartons commonly used in the market needs to be completed with the help of external tools or materials (such as staples and tapes, etc.), and the cartons produced in this way have the following disadvantages: [0003] First, the cost is high and the fabrication is complicated. The bottom of the traditional carton needs to be joined by multiple pieces, and the process is complicated and cumbersome; and the staples or tapes used to join the bottom of the box will incur additional costs, and the completion of the staples or tape...

AI Technical Summary

Problems solved by technology

[0003] First, the cost is high and the production is complicated

The bottom of the traditional carton needs to be joined by multiple pieces, and the process is complicated and cumbersome; and the staples or tapes used to join the bottom of the box will incur additional costs, and the completion of the staples or tapes will cost more production time and effort

[0004] Secondly, it is not strong enough, and the contents are easy to leak from the bottom of the box

Because the bottom of the traditional box is completed with the help of staples or tapes, the weight of the contents is very limited, and if it is pulled carelessly during transportation, the joints of the staples or tapes at the bottom of the box will be torn. , causing the item to fall from the bottom of the box

[0005] Again, not pretty enough

Because the bottom of the box is not made of a whole piece of cardboard, but the divided small cardboard surfaces are joined together with staples or tapes, so the beauty is greatly reduced

[0006] In addition, it is not environmentally friendly

Cartons joined by staples or tape create additional, environmentally damaging waste

[0007] Finally, it is easy to cause damage to the contents

Especially the bottom of the box with staples is more likely to cause scratches and scars on the items

[0008] In summary, there are obviously inconveniences and defects in the actual use of the existing cartons, so it is necessary to improve
