Technical Field

[0001] The utility model relates to the technical field of plastic packaging boxes, in particular to a pressure-resistant and drop-proof plastic packaging box. Background Art

[0002] Plastic is a type of material that uses synthetic or natural polymer resins as its main material. After adding various additives, it has ductility under certain temperatures and pressures and can fix its shape after cooling. It is often used as a raw material for making packaging boxes. It has now become one of the four important materials in the packaging industry and has a relatively important position. The main function of plastic packaging boxes is to package specific products, store, isolate and protect the products, and facilitate subsequent transportation and use.

[0003] Today's plastic packaging boxes often have a simple structure, with only a single-layer structure. Moreover, due to the limited strength of plastic itself, it does not have strong pressure resistance and drop resistance. As a result, when storing valuables, it is easy to cause damage to valuables, which is not conducive to transportation and difficult to meet usage needs. Utility Model Content
