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.

Reliability - Altitude Testing


Companies need to make sure their packaging protects the product not only on the ground, but at the high altitudes reached during air transport.


Altitude testing (also known as reduced pressure testing) simulates the reduced air pressure experienced at higher elevations and the impact on the integrity of the product and/or package system. Sealed flexible systems have the potential to fail when exposed to altitude stress. In fact, altitude exposure by truck transport often exceeds the levels experienced in commercial air transportation.

An altitude test is either a pass or fail. Pouches may burst at the seams if the internal pressure of the flexible packaging cannot equalize. Additional packaging costs may be incurred to pull a partial or full vacuum on the packaging in order to avoid the effects of altitude. Altitude can also affect your product when the package is jeopardized.

Remember that pressure differentials can cause potentially harmful stress on any enclosed volume whether that is container in the product or the package system. Altitude levels of 2.5 kM (8000 feet) are common in commercial aircraft shipping and up to 3.5 kM (12000 feet) during truck transport.
