Automated syringe blister packaging machines allow syringes to be fed onto an assembly line and evenly spaced out. The machine places the syringes into plastic preformed blister trays. The cover film is then applied to the top of the blister pack and sealed. Some blister packaging machines are also equipped with the ability to apply labels to the blisters or the film cover. Tray pack machines function in a similar way – syringes are loaded and seal the syringes inside. Alternatively the tray can be packaged into a plastic or cardboard, which can then be labeled.
