Fluorination is a process that minimizes the distortion of the container, referred to as paneling, by treating both the inside and outside surfaces of the plastic bottle with fluorine gas.
What are the levels of fluorination?
There are nine different levels of fluorination. Each level offers a different barrier level….How is fluorination performed?
- time (how long it was in the reactor)
- temperature (how high the temperature is elevated)
- pressure (amount of pressure used);
- amount of fluorine introduced.
What does fluorination mean?
Definition of fluorinate transitive verb. : to treat or cause to combine with fluorine or a compound of fluorine.
What is the fluorination process?
Fluorination is a process whereby plastic containers are exposed to fluorine atoms under controlled conditions. This improves the high-binding energy and resistance of the plastic container and therefore, lower permeation. Shielding against solvents that otherwise permeate and chemically attack various plastics.
What are fluorinated bottles used for?
Fluorinated bottles are plastic bottles that have undergone a special fluorination treatment to make them safe for packaging certain liquids like some chemicals that otherwise react with plastic or result in paneling, permeation, material loss and have to be packaged in more expensive glass or metal containers.
Is all HDPE fluorinated?
Not all kinds of plastic can take fluorination. However, you can select from opaque or clear plastic, LDPE, HDPE, PP, PVC, and other plastics that can be fluorinated. The kind of plastic and the level of fluorination are important and depend on the products you want to package.
What are fluorinated containers?
Are fluorinated bottles recyclable?
Fluorinated bottles are also just as recyclable as any other bottle of the same material.
What causes bottle paneling?
Paneling occurs when the pressure inside a plastic bottle becomes less than the ambient air pressure outside, causing the walls of the bottle to partially collapse inward. The result is an aesthetically unappealing product package with a distorted shape and badly puckered or wrinkled labels.
Why is HDPE fluorinated?
The fluorinated surface (inside and out) improves barrier properties and reduces solvent absorption while enhancing long-term container performance and prevents loss due to permeation.
What is fluorination used for?
The Fluorination Fix Plastic bottle paneling is prevented by a process called fluorination, in which the surface of container is treated by fluorine gas. Fluorine atoms bond to the plastic, creating a permanent protective barrier.
What do fluorinated bottles do?
Fluorinated bottles are plastic bottles made safe through the process of fluorination for the packaging of certain chemical liquids that would otherwise react with plastic. Fluorination bonds fluorine atoms to a plastic’s surface, which creates a permanent protective barrier.

What is HDPE plastic?
High-density polyethylene (HDPE) or polyethylene high-density (PEHD) is a polyethylene thermoplastic made from petroleum . It is sometimes called “alkathene” or “polythene” when used for pipes. With a high strength-to-density ratio, HDPE is used in the production of plastic bottles, corrosion-resistant piping, geomembranes, and plastic lumber.
