Compression Testing

Compression Testing

Compression Testing for shipping cases is performed to assist in stacking analyses in warehouse storage, vehicle transit and sterilizer chambers and to study the effect of compressive forces on candidate shipping cases. Many factors go into the design of a successful RSC shipper, including board weights, board strength, flute size and the number of walls. External factors such as temperature, humidity, stacking method (e.g., column stacking vs. interleaved stacking) and pallet patterns (e.g. overhang or not), as well as product weight and whether the product is supportive, all play a role in designing the correct shipper for the job. The actual compression strength of an individual case measured by this method is compared with the required static and dynamic stacking strength derived from the application of the McKee's formula.
