Westpak is certified to conduct product/package integrity testing to help guarantee successful delivery of products worldwide by any means of transportation.

Westpak is accredited to ISO/IEC 17025-2005, one of the most rigorous standards available for a mechanical testing laboratory.

Life Science Conditioning

Environmental Conditioning is a process of subjecting a test specimen to various temperature and humidity conditions in order to determine the effect of these conditions on the test specimen. Often this conditioning is conducted prior to other tests such as mechanical or package performance testing in order that the test specimen be exposed to a full range of potentially harmful temperature and humidity levels. The testing is conducted in an environmental chamber designed to maintain tight controls over both temperature and humidity as well as the rates at which these quantities are changed. The test levels chosen and rates of change between these levels are often typical of what might be encountered during an extreme distribution cycle, for example, or storage for an extended period of time.

Many materials from which containers and packages are made, especially cellulosic materials, undergo changes in physical properties as the temperature and the relative humidity (RH) to which they are exposed are varied. Most plastic components change strength in direct proportion to changes in temperature.
