Bloom Seal ^® process is a unique technology to pack a variety of formulations.

The Bloom Seal ^® process is based on the formation of a fluorocarbon barrier layer on the polymer surface. The basic reaction, which occurs with HDPE, is a substitution of Fluorine, in place of hydrogen atoms on the polymer backbone as shown in the Figure 1.

Figure 1

The Bloom Seal ^® barrier is effective in minimizing the permeability of non-polar solvents through a polymer surface. Since Bloom Seal ^® modifies only those polymer molecules near the surface, there is no measurable change in the mechanical properties such as tensile strength and impact resistance.
The Figure 2A shows untreated HDPE container wall resulting in evaporation and product weight loss.
