In an alu-alu blister or CFF (cold formed foil) blister the sealing machine uses an aluminum based layer for both the base and lidding, particularly in Europe, India and East Asia. Since these economies are adept to blister packing, they require alu-alu packing that increases the shelf life of the product and provides protection till its final use. Hence most alu-alu blister sealing machines around Europe, India and Asia are built to use nylon, aluminum and PVC layering. The use of this mixture makes the packaging more efficient at providing protection from light, heat, oxygen and moisture.
Alu-alu blisters are made using a cold forming technique where the machine presses the laminate onto a molding tray without the use of heat. The cold plate has pins to create the cavity for placing the product. After which, the sealing tool puts an aluminum foil lidding on the blisters.
