TECHNICAL FIELD

[0001] The application relates to the technical field of packaging boxes, in particular to a traceless packaging type corrugated paper box. BACKGROUND

[0002] The corrugated paper box is a packaging product made of corrugated paperboard through die cutting, indentation, nailing or sticking. The paper box is widely used and has the largest amount among various packaging products. In addition to protecting goods, facilitating storage and transportation, the paper box also beautifies goods and promotes goods. In addition, the corrugated paper box is a green environmental protection product, which is beneficial to environmental protection and loading and unloading transportation.

[0003] Generally, the corrugated paper box is sealed by using adhesive tape when being packaged, which is relatively convenient.
