[0002] The cherry tomato packaging box is a paper packaging used for packaging and transportation of cherry tomatoes. It is made of corrugated paper as a whole. It is pre-cut into a target shape, and then its left and right sides and front and back sides are folded toward the middle to form a paper box with an opening on the top.

[0003] However, this type of paper box is different from traditional paper boxes in that, during the folding process of the left and right sides and the front and back sides, the paper box is flipped twice, so that a hollow "box edge" with an N-shaped cross section is formed on the side. The "box edge" makes the entire paper box have a stronger pressure-bearing capacity and is less likely to deform during transportation. Secondly, the hollow shape of the "box edge" naturally forms a shock-absorbing part, which is used to play an anti-collision protection effect during transportation; However, the traditional box folding machines currently on the market can usually only achieve a single fold, and the side formed by the folding does not have the required hollow "box edge" structure.
