Retailers using the Flexis Oxygen Valve receive their products in
individual trays, each covered with a clear high-barrier lidding film
equipped with the two-part valve. The valve’s upper layer can be clear
or printed. When that layer is peeled away, it reveals a second,
permeable layer that permits the entry of oxygen. Once the top layer is
removed it does not require the entire package to be relabeled. The
method allows retailers to pick for the display case any number of
packages that arrived in a shipment.
