[0002] A packaging box is a container used for packaging and protecting goods. It is usually made of materials such as paperboard, plastic or metal, and has various shapes and sizes that can be customized according to different product types and needs. Packaging boxes are very important in the production and sale of goods, as they not only provide protection for the products, but also increase their value and appeal. However, existing packaging boxes often have the problem of breaking when exposed to water, and have poor flame-retardant properties. Since they are made of paperboard, they can easily catch fire when reaching the ignition point. In addition, existing packaging boxes have poor compression resistance and can deform when subjected to impact or pressure, affecting the quality of the products inside. Furthermore, existing packaging boxes have poor thermal insulation properties and low hardness, causing deformation of the packaging box body when stacked. The service life of existing packaging boxes is short and they cannot be reused.
