Not all barriers are the same.

Not all silage films are created equal. Bananas show us that. Our Sealpro® Silage Barrier Films are nine and 11 microscopic layers thick. The middle layer contains protected barrier polymers. There are several barriers or “vapor” films out there with, in our experience, varying results. If the barrier is of poor quality, if there isn’t much (or any) of it, or if it is not evenly distributed, the film’s effectiveness is compromised.

Name the most oxygen-sensitive fruit you know. (It’s bananas). Leave them exposed to oxygen and they get brown (Oxidize). Bananas are perishable. So is silage.

To show how oxygen barrier film works and how all films are not created equal, we developed a simple, visual test using bananas. There are also lab tests that numerically rate oxygen transfer rate (OTR), and we test on a regular basis. Nearly 100% of the time, the lab tests match our Banana Test.

To prove that no special treatment was given to Sealpro®, an independent nutritionist in Tulare, California volunteer-proctored a Banana Test. The bananas were sealed under his watch, in his office. He photographed the bananas for 19 days. The results speak for themselves. Note Sealpro PROTECT® (light purple film, lower right corner) and Sealpro TITANIUM® (gray film, middle lower) have puffed up by the end of the test, demonstrating how a true oxygen barrier film does not allow oxygen in, and doesn’t allow fermentation gasses out.

NOT ALL OXYGEN BARRIER FILMS ARE CREATED EQUAL. SEE THE DIFFERENCE!
