Test
data on fluorination barrier treated bottles
|
| These
charts show the superiority of fluorinated containers
(Level 1) compared to untreated bottles for packaging
chemicals. The non-pigmented HDPE bottles were 125
cubic centimeters in size with a nominal wall thickness
of 0.5 millimeters.
These
weight loss tests were conducted in ovens at 50°C.
The container openings were heat sealed with a liner
made of aluminum foil polyester-polyethylene to insure
leak tightness. Data was obtained by weighing the
bottles before and after the 28 day test.

|
| To
confirm compatibility of your product in barrier
treated bottles, we urge that you treat sample
bottles (exactly like those the customer will use
on a commercial basis), fill them with their product,
and follow the testing protocol described in 49
CFR Chapter 1, Part 173, Appendix B.
If,
following compatibility and permeation testing,
either the product formulation is modified,
or the bottle composition is changed (resin
supplier, type of resin, manufacturer, color,
concentration of colorants, additives, etc.),
or both, we caution you to again test treated
samples with your product formulation.
