within the bag seal. You may need to cut open the bag and re-seal
it, or use an entirely new bag. Partially freeze foods with excess
liquids, prior to vacuum sealing.

have punctured the bag. If you find a puncture hole, seal the item
in an entirely new bag.

sealing properly. Cut bag open and wipe top inside of bag and
