Abstract A blister packaging system is disclosed that is a sheet/film or sheet/sheet package designed to be easily recycled and may be of materials that have a high recycled content without degradation in performance. The blister package is composed of a thermoformed or vacuumformed front blister made from polyethylene terephthalate (PET), PET-G or R-PET which may have a significant pre or post-consumer recycled content sealed to a back film or sheet made from polyethylene which may also have a significant pre or post consumer recycled content. The film or sheet back may be printed on either or both sides and is coated on one side with an adhesive which bonds to the blister in the filling/sealing process.
