Hi David
The molecular sieve is a dessicant used to adorb the acetic acid, moisture or vapour from the film. It does not necessarily mean that by using the molecular sieve you have salvaged your film. It is just part of a procedure in trying to protect your film from Vinegar Syndrome. The film should be stored in a climate controlled environment. If you dont frequently use the film, you can seal it in a plastic bag it and freeze it. However, make sure you have cleaned the film with film cleaner and inspect it for any further problems it might have.
