TECHNICAL BULLETIN

Oxygen and Moisture Barrier Properties

The following information contains observations made from testing laminates of several clear, ultra high barrier plastic films. This preliminary data is not to be considered as a recommendation for the use of a particular high barrier film or film laminate. There are other high barrier laminates which have not been tested and which may be alternate candidates for similar end uses.

This information is to be used as a guide only and we recommend you contact the barrier film supplier of your choice if more detailed information is required. The testing procedures used to compile this data are laboratory evaluations and do not encompass the end use testing required before final product selection.
