Hello.

Such a slow weight loss would have nothing to do with the seal, as UMAi Dry® will dry just fine with a compromised seal. Either you are not drying in a modern frost free refrigerator in regular use located within a consistently room temperature environment -or- your weight calculations are somehow incorrect. It is difficult to troubleshoot without knowing your set up, but a poor seal or lack of contact between UMAi Dry® and meat surface cannot explain such slow weight loss.
