The optimal cushioning design must be carried out to protect the products sufficiently from mechanical shock generated during transportation. The final step of the cushioning design procedure is the testing of the prototype package. The drop test has carried out as an evaluation of shock absorbing package. The free fall test is used the free fall drop test equipment. The test has a fundamental problem which cannot be simulated perfect drop perpendicularly to the dropping surface of the package. On the other hand, the controlled shock test is also carried out as a simulated drop test by using a mechanical shock test machine which is used in an evaluation of the mechanical shock fragility of product. The test has supposed the bold approximation of the packaging dynamic condition. We can select the drop test from the above two methods, but are shock responses of the product by the two test promised perfect equal? Many drop tests of the dummy packaged carton box which contains the transport environment recorder are carried out used by the free fall tester and the mechanical shock test machine. The results by the two test procedures are compared to confirm the equivalence of the drop testing by the free fall test and the controlled shock test.
