The Charlie Bag is a 4 mil, sealable bag which insures that no body fluids will get into the x-ray cassette and become a harbor for germs. Trapped blood and body fluids also damage the cassette causing you to replace the x-ray cassette. The Charlie Bag offers protection to patients and workers against MRSA and other Hospital Associated Infections which are found on x-ray cassettes. One of our major goals is to help stop MRSA, keep your equipment and workers safe.
