Abstract

The invention relates to an air-drop type storage-transportation packaging box convenient to stack and a preparation method of the packaging box, belonging to the package and transportation fields. The packaging box comprises a box body and a box cover which are mutually buckled, wherein the box body and the box cover are prepared from the following raw materials in parts by weight through rotational molding: 50-70 parts of linear low density polyethylene, 50-70 parts of low density polyethylene, 40-80 parts of high density polyethylene, 10-30 parts of medium density metallocene polyethylene and 1-6 parts of a coupling agent; and rig grids are arrayed at the bottom of the box body or the top of the box body or the box cover in a matrix manner, the rig grids at the top of the box body or the box cover are mutually seamed and clamped with the rig grids at the bottom of the box body on an upper layer so as to form embedding and splicing type anti-dislocation stacking structure. The packaging box is produced from the polyethylene materials with different densities through mixing and rotational molding, and modularized rid grid structures are arranged at the top and the bottom of the packaging box, so that the strength, impact resistance and packaging efficiency of the packaging box are improved, and the mutual stable stacking of different specifications of packaging boxes is realized.

Description

technical field [0001] The invention belongs to the field of packaging and transportation, and relates to a packaging box for storing and transporting precision instruments and weapons, in particular to an air-dropped rotational molding storage and transportation box with a modular rib structure. Background technique [0002] The quality of ammunition is closely related to the combat effectiveness of troops. However, the protective performance of existing ammunition packaging is not ideal. The quality of the packaging boxes is generally heavy, and the performance is uneven. Among them, wooden packaging boxes have low strength, poor protection performance, are susceptible to insect bites and rats, and are flammable and combustion-supporting; steel packaging boxes are high in strength, but are easy to rust, sparks are easy to be generated when collided, and heat conduction speed is fast, which poses safety hazards for storing and transporting dangerous goods. The material of F...
