The invention discloses a composite packaging material. The composite packaging material is provided with a plurality of units used for forming individual packages, and the composite packaging material is provided with a base layer, a printing layer and a waterproof layer from inside to outside; and each unit is provided with a partial structure of a complete identification code, and the partial structures on two of the units are assembled into one complete identification code. The composite packaging material with the identification code partial structures printed has the advantages that theoccupied area of design space on the surfaces of the individual packages is reduced, the complete identification code is formed through splicing the partial structures, located on different individualunits, of the identification code, and the interestingness of a reward link is increased.
