Package Distribution Testing

Distribution Testing - often referred to as Shipping Testing - is the practice of conducting tests on a package system that simulate the distribution environment. Laboratory testing provides a controlled and repeatable setting where the ability of shipping units to withstand the distribution environment can be determined. This is accomplished by subjecting package test samples to a variety of tests such as impact, compression, vibration, environmental conditioning, and altitude. These tests replicate a significant portion of what the package will encounter in the actual distribution environment.

The optimum protective package consists of a product of known ruggedness and a protective package system which together provide sufficient resistance to damage during distribution. One of the best ways to determine if a package is indeed “optimum” is to test the packaged product in the laboratory setting.
