[0002] Packaging boxes are an important type of packaging material in rigid packaging technology. They are rigid or semi-rigid materials with high strength and are not easy to deform. Their structure is similar to that of packaging boxes, but their volume and appearance are usually larger than those of packaging boxes. The two are usually divided by 10 liters. Packaging boxes have high overall strength, strong deformation resistance, and large packaging volume. They are suitable for transportation packaging and outer packaging. They are mainly used for solid grocery packaging. Among them, convenient plastic packaging boxes are a packaging container made of plastic materials. They are light, easy to carry, and reusable. They are widely used in logistics, transportation, warehousing, and home organization. In home scenes, convenient plastic packaging boxes can be used to organize and classify various items, such as clothing, toys, stationery, etc., to make the home space more tidy and orderly. In commercial scenes, it can also be used for flat display of supermarket goods to improve the recognition and attractiveness of goods.
