Gels and Barrier Integrity

Q.

Is there a published case study for barrier integrity of gels and contaminants?

A.

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.
