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.

Westpak is certified to the requirements of ISO 9001-2008 for quality management, and to ISO 14001-2004 for environmental management and sustainability efforts.

Package testing - Environmental Conditioning

One of the first test processes often required prior to conducting physical testing on the package, container, or packaging component being evaluated is Environmental Conditioning; this process brings the item to be tested into equilibrium with specific temperature and humidity conditions prior to testing.

Environmental Conditioning is conducted in an environmental chamber designed to maintain tight controls over temperature and humidity. The test levels chosen and the 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.

The temperature and moisture content of the packaging material to be tested is critical, as are the environmental conditions during testing. For example, paper based materials are hydroscopic and will change their strength characteristics as they absorb or release moisture.
