Clamshell packaging will typically have a hinge on one side to allow for a product to be sealed between the front and back panels. Sealing is usually done through RF or heat sealing, welding, or buttons on the clamshell package. Jamestown Plastics specializes in designing custom plastic clamshell packaging. Blister packaging, on the other hand, will have the plastic attached to a paper header card through adhesive or sometimes by stapling. If using adhesive for the header card, the blister will typically not be recyclable as the adhesive contaminates the plastic. The Clamtainer and Click It Card, from Jamestown Plastics, can help solve this problem by separating the messaging from the plastic.
