02 pattern corrugated box was taken as research objective. Local composite strengthening of the corrugated box was carried out according to the weight-bearing principle of cartons and intended strength requirements to enhance the physical properties of cartons in circulation, stacking, storage, and other aspects and realize reduction production of corrugated box. Experiment and production practice showed that under the premise of selecting appropriate composite materials and processes, application of the local composite strengthening technology can produce the carton with the same compressive strength whereas the cost is 13% lesser than the conventional process. The purpose was to provide guidance for reduction design of corrugated box.
