Environmental package testing services includes accelerated aging testing, shelf life studies, and thermal shock testing. Environmental testing involves exposing a package or product to controlled temperatures and humidity in order to reproduce the conditions that the package/product is expected to survive in its transportation, storage and operating life. After exposure, the package or product is assessed for damage. Packaging must be tested and validated for its ability to withstand the transportation, storage and operating environments that it will encounter. Environmental testing laboratory, performs testing services based on those environments that the packaging is expected to endure. In the military, aerospace & automotive industries, environmental package testing is considered as incorporating all kinds of stress that a packaged product might experience (including mechanical elements such as shock testing, vibration testing and operational stress) plus temperature and humidity.
