Gels and Barrier Integrity
Is there a published case study for barrier integrity of gels and contaminants?
Last Updated On April 18, 2011
Most film producers have conducted barrier integrity tests on film possessing high gel count, however, there is a limited amount of published data available. In terms of bacterial barrier, the presence of a gel will not impact the barrier of a film so long as the gel’s size is not so large as to have caused a hole in material adjacent to the gel.
Gels in multilayer high-barrier films (oxygen, moisture, CO2) will have minimal impact on total package barrier.
