Compatibility testing of fluorinated samples for commercial production

Fluoro-Seal recommends that all fluorinated containers be qualified for compatibility with the actual products they are to hold. A compatibility test* consists of filling Fluoro-Seal treated samples of the proposed container with product and measuring permeation via weight loss.
It is important to perform tests with containers that are identical to the ones that will be used for your production since barrier properties will vary for different containers. Some of the factors that affect barrier treatment include the manufacturer, weight, resin package, colour concentrate carrier, pigment type, closures, label, wall thickness, level of regrind resins, and shape. A change in any one of these factors can affect the barrier level of the package.

Changes to product formulation or container after compatibility tests

Any change made in the formulation of the product to be packaged and/or the container originally used for testing after the package has been qualified and approved will require the entire package be re-qualified.
