This type of blister packaging machine forms “plates” of plastic blisters. A flat-plate blister machine uses heat and a die to create the cavities for the blister packaging, and then air blows on the plates to make the blisters stand out. After the plates are made, the blisters are filled and a backing is sealed to the plate. Products such as pills and medications are commonly packaged using flat-plate blister machines, as the blister packaging helps regulate dosage.
