Blister packing is the most common primary packing type for tablets and capsules. Different blister packaging materials are used for different products. Those who pay attention to medicine packing might notice that most medicines use aluminum plastic packing, while some others use alu-alu packing.

Both sides of the alu-alu packing blister are aluminum foil, which is also called cold-forming foil. Such type of foil is with advantages such as high-barrier, high adaptability, easy forming, good light barrier, good extension, and easy to be sealed with aluminum blister foil into full aluminum packaging.
Cold-forming foil is a combination of aluminum foil outside and polymeric films inside. It is suitable for blister packaging of both tablets and capsules which might be sensitive to moisture, oxygen, light, and chemicals.

Different use of Alu-Alu Packing and Aluminum-Plastic Packing
