The expiration date should be on the original container of all sorb packages.
However, if you bought a fresh sorb supply, the shelf life is generally about 5 years based on the expiration dates of my containers.
They need to be stored in a cool and dark environment. I usually keep them either in the closet or the bottom shelf in the dive room.
