A potential method for the specification of microbial barrier properties.
A microbial barrier test to determine the barrier characteristics of porous packaging materials has been developed that will allow real-time testing in manufacturing environments. None of the barrier challenge tests used to date have achieved universal acceptance and they have taken days to perform. The new physical test means that quality control can be conducted on the manufacturing line in 10 minutes. The findings of tests conducted on porous barrier materials are reported.
