Detect water vapour in packaging
Water vapour transmission can have a negative impact on food, pharmaceuticals and other products in packages. Now a new standard is providing a way to test for water vapour transmission through flexible barrier materials using electrolytic detection sensors.
The ASTM International standard (soon to be published as F3299) was developed by the committee on primary barrier packaging (F02).
Traditional methods relied on infrared sensors but this latest standard may support instruments that use alternate sensor technologies that are both more sensitive and less expensive.
