Kordon Breather Bag 12"x19" 25ea

These Breathing Bags are constructed of a special film that has a micro-porosity that allows the transfer of simple and complex gas molecules through the plastic wall of the bag. Carbon dioxide and oxygen in particular, as well as other gases - are constantly passing through the plastic bag  via the micro-porosity.  In other words - the plastic has gaps so small that water molecules cannot pass through - yet gas molecules can move freely. This provides a true "breathing" bag in place of a non-porous "barrier" bag as is used in traditional plastic polyethylene bags. As long as there is a breathable atmosphere outside the Breathing Bag, the fish or animals inside will not run out of oxygen.
 Kordon breather bags are 1.5 mil in thickness, tough and Flexible. Since the bag does not need added oxygen to sustain fish, you can ship in smaller packages and no air means no sloshing and no stress.  The Breathing Bags are sealed with as little air inside as possible.  Ideally only water touches the inner surface of the bag.  No air chamber of added oxygen means no slosh-zone and turbulant travel for the fish inside.  You can test this by laying a filled Breathing Bag on a flat surface and allowing the fish to settle down. Picking up one edge of the bag - you can roll it until it is totally reversed - upside down - yet the fish inside will not move at all.  No sloshing, no jiggling... no stress.  Less stress equals less losses  or injuries during shipping or transfer of live fish.
