Material selection is affected by several variables, including sterilization method, clarity (clear or opaque), sealing techniques, operating and environmental temperature constraints and end-use. The following considerations reveal what type of information the thermoformer needs.

Blisters are one of the most common packaging designs. An inner lid can be added to protect and/or hold the contents securely during sealing and shipping. To create a sterile barrier, most trays can be heat sealed with lids of Tyvek or other materials, such as paper, foil laminations, and plastic films.
A Blister with an inner tray is well suited for applications in which the package is more than just a receptacle. Trays can be custom designed to fit a wide variety of applications, and they are ideal when the order of use is of primary importance, such as in procedure kits. Inner trays can be designed with special features, such as a pocket to hold a vial, or graduated well to measure a liquid.
