At present, health food and drug tablets, capsules packaging in the form of blister packaging is more and more common, aluminum blister is also known as blister eye packaging, referred to as PTP(PressThroughPackaging). The aluminum foil used in blister packaging is a sealing material dense in the pharmaceutical plastic polyvinyl chloride (PVC) hard sheet, so it is also called the cover material. In modern packaging, almost all products requiring opaque or high barrier composite materials use aluminum foil (Mingtai products) as a barrier layer, because aluminum foil has a highly dense metal crystal structure, which can completely block any gas, so it is widely used.
Aluminum foil is used for blister packaging, which is expected to account for about 60% to 70% of the future pharmaceutical tablets and capsule packaging, and is currently one of the most promising pharmaceutical packaging materials.
