FLUORINATION:

Vision Packaging is able to provide complete fluorination services to improve the compatibility of HDPE with problem chemicals.  The fluorination process may also be used for aesthetic purposes, further enhancing the matte effect, thereby creating a natural matte appearance.

Fluorination of HDPE is used to improve the solvent barrier properties of this polymer. Fluorine is chemically bonded to the chain-like molecules on the outermost surfaces of the plastic.  The reaction is permanent and forms a thin fluorocarbon polymer surface layer with heightened chemical stability.

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, then 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.
