Abstract
A method for storing and preserving moisture sensitive products includes providing a moisture tight container (400) having an insert (300) made from a desiccant entrained polymer that is less than 3.25 g in mass, disposing a plurality of moisture sensitive products into the interior compartment when the container is in the open position, and moving the container into the closed position, thereby creating a moisture tight seal between the lid (420) and the container body (401). The container provides a shelf life to the moisture sensitive products of at least 12 months. The container, when in the closed position, has a moisture vapor transmission rate, at ambient conditions of 30° C. and 75% relative humidity (RH), of less than 500|ig/day.
