In order to achieve the goal of product protection, the environment friendly materials and innovative structure design of the packaging for wall-hanging air conditioner outdoor unit were discussed. Based on the product packaging test, the protection function of the environment friendly materials for the product was verified. The reliability of the selection of environment friendly materials and optimization of structure design was verified by tests of transporting, dropping, stomping and stacking. The structure design of green product packaging had a number of advantages such as saving energy, resources and packaging materials, being recyclable, avoiding or reducing waste generation, and reducing environmental pollution. Wall-hanging conditioners could use honeycomb material, EVA material, corrugated board corner protector, and innovative structures designed using corrugated paper material, which was not only suitable for fully automated production process operations, but also for better protection of the product.
