BASCO has partnered with Inhance, who has developed special methods to achieve optimum barrier performance in plastic bottles and containers without causing undesired degradation or decomposition.
What is plastic container fluorination?
The Fluoro-Seal Process™, also known as “surface fluorination”, is used to impart hydrocarbon barrier properties to plastics.
Inhance offers nine different types of fluorination. Higher levels are used for stronger permeators and provide more barrier on the inside and outside surface area. Each of the nine levels of fluorination differs from one another based on four things:
- Time spent in the reactor chamber
- Temperature of the reactor chamber
- Air Pressure applied to the plastic - amount of pressure
- Quantity of Fluorine used
Why should I bother with surface fluorination?
The short of it: To save money by preserving the quality of your product and by reducing spoilage. Inhance will fluorinate plastic bottles and other plastic containers to increase barrier properties and adhesion. Fluorination of polyethylene and polypropylene can eliminate or reduce problems from chemical attack including:
- Paneling and distortion of the container
- Softening of container
- Label blistering
- Product weight loss
- Container discoloration
- Odor emission
- Flavor, fragrance and/or active ingredient loss
Fluorination of polyethylene and polypropylene can increase:
- Shelf life
- Ink wet out
- Closure retention
- Product integrity
How do I get started on fluorinating my products?
After placing your order at BASCO, we will ship your plastic containers directly to Inhance for treatment.
Inhance will take your plastics out of their shipping packaging, and put them into large FDA compliant stainless steel bins, load them into a chamber, and expose them to elemental fluorine gas and other proprietary gases.
During this process, the fluorine gas creates carbon fluorine bonding on the inside and outside surface area, in essence blocking the porous wall of plastic, helping to eliminate or reduce migration of aggressive chemicals.
Inhance's fluorination process is FDA compliant, but remember: You must choose FDA approved containers for food products.

Fluorine substitution increases the density of the surface. Free volume is decreased, reducing solvent permeability.
Radicals generated during the high-energy process cause a slight degree of polymer cross-linking on the surface, locking in the new structure and making the treatment permanent. This also minimizes swelling and plasticization effects, thereby increasing chemical resistance and suppressing permeability.
Surface energy increases significantly, due to an increase in polarity of the surface. The net effect is reduced solubility of low polarity organic liquids and excellent surface barrier properties.
The desired barrier performance is accomplished by controlling the degree of fluorine substitution. This requires consideration of plastic material composition, additives and other materials present, the container or tank characteristics, the expected storage conditions, and the composition of the liquid to be contained.
Careful maintenance and control of the relative gas mixture, the reaction temperature, and the exposure time enables the formations of very stable covalent carbon-fluorine (C-F) bonds to a surface depth of several nanometers.
