Improvement of Package for Fan-propeller of Commercial Air-Conditioner Outdoor Unit.

Daikin Industries Ltd., Oji Container Co.,Ltd , Tsuwasangyou Co., Ltd.

Propeller fans of different shapes of 3 and 4 blades are inhibited from rotating and protected from impact by bending the inner corrugated cushioning material and the inner flap of the outer case. As a result, working time was significantly shortened compared to packing using foamed cushioning material.    

By changing from polyurethane foamed cushioning material to corrugated cushioning material, waste can be reduced and recycling becomes possible, so it was also improved in terms of the environment.
