    Abstract

    Blister packs are commonly used to package hard gelatin capsules. Shelf life restrictions of the blister pack components can be problematic for low volume users due to the requirement to purchase larger quantities. Here we investigated the physical and chemical properties of blister pack foils to determine if a change in their nature occurred when the expiry date was exceeded.
