In-line Fluorination Process:
In-line fluorination is a process adapted to standard blow-molding technology to produce an effective permeation barrier at the inner walls of plastic containers. Unlike post treatment processes, which require container reheating and may result in distortion or dimensional changes, barrier treatment occurs during the normal blow-mold cycle as the container is being formed. The in-line fluorination process results in a permanent chemical modification of the container surface. It does not leave a residue or cause discoloration to the container. The treated surface is highly resistant to deterioration from chemical attack or mechanical abrasion. Where hot filling is possible, the barrier integrity is maintained.
This inner barrier resists permeation by solvent-based chemicals up to 500 times better than untreated HDPE, making the containers suitable for packaging of janitorial, industrial and consumer products such as d-limonene-based cleaning products; industrial chemicals and solvents; lawn and garden chemicals; automotive waxes, polishes, oils and additives and agricultural chemicals.
