[0002] A cardboard box is a three-dimensional shape, composed of multiple facets that are moved, stacked, folded, and enclosed. In three-dimensional composition, facets divide space; cutting, rotating, and folding different facets creates different emotional expressions. When designing the display surfaces of a cardboard box, attention should be paid to the connections between the display surface, sides, top, and bottom, as well as the placement of packaging information elements.

[0003] A cardboard box packaging machine is an automated device specifically designed to package various items (such as gloves, food, and pharmaceuticals) into boxed products. Its main functions include improving the appearance quality of the product and making it more convenient to use. Side folding, tongue-folding, and sealing are common cardboard box packaging techniques. These involve folding the sides of the box, folding the side flaps, inserting the tongues, and sealing the box. The side flaps are used to fold and flatten the sides of the box for easy closure and transport. The tongue-folding sealing refers to setting a tongue structure at the top or bottom of the box, which is then inserted into corresponding slots to close the box. This technology is widely used in the packaging of various products, such as food, pharmaceuticals, and cosmetics. These techniques improve packaging efficiency, reduce labor costs, and ensure the safety and stability of the product during transportation and storage, protecting the contents from damage.
