Temperature and Humidity Testing Conditioning

Medical device packaging is subjected to prescribed temperature and humidity levels in preparation for distribution testing (i.e., compression, drop/impact, vibration). The environmental conditioning is necessary because paper-based materials, which are used in most packaging systems, experience changes in physical properties as temperature and humidity change.
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.

Exposure is conducted via a dedicated 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 documented in the customer’s protocol and encompass what might be encountered during the actual distribution cycle.
