Is the thickness of aluminum foil required for pharmaceutical packaging?

Pharmaceutical packaging on the thickness of aluminum foil is required, different types of pharmaceutical packaging aluminum foil thickness requirements are different, the following are some common situations:
PTP aluminum foil: The general thickness is between 0.02mm and 0.04mm. For example, the thickness of PTP aluminum foil for common tablets and capsules is 0.02mm to 0.03mm. This thickness range can ensure that aluminum foil has good barrier properties to prevent oxygen, water vapor, etc., from entering the packaging to affect the quality of drugs. At the same time, it also has appropriate strength and flexibility, which is convenient for molding and hot sealing on the blister packaging machine. And easy for patients to tear open access to medicine. For some special drugs that require higher barrier properties, PTP aluminum foil with a thickness of 0.03mm-0.04mm May be selected.
Aluminum foil in the aluminum-plastic composite film: as a component of the aluminum-plastic composite film, the thickness of aluminum foil is usually about 0.015mm-0.025mm. For example, the aluminum-plastic composite film used for pharmaceutical packaging such as granules and dispersions, of which the thickness of aluminum foil is generally 0.018mm-0.022mm. Such a thickness can not only be better combined with plastic film, play the barrier advantages of aluminum foil, but also make the composite film as a whole have good flexibility and heat sealing performance, to adapt to the various process requirements and use scenarios of pharmaceutical packaging.
Cold stamping aluminum foil: the thickness is generally 0.15mm-0.30mm. The cold stamping process requires the aluminum foil to have high strength and rigidity to ensure that it can form a stable shape during the stamping process and protect the drug during subsequent packaging and use. For example, some cold stamping packaging for high-end drugs and special dosage forms will use aluminum foil with a thickness of 0.20mm-0.30mm to provide more reliable packaging protection.
These thickness requirements are not absolute and will be adjusted according to the characteristics of the drug (such as whether it is particularly sensitive to light, oxygen, and water vapor), the form of packaging (such as the size and shape of the blister), the production process (such as heat sealing temperature, pressure, etc.), and cost.
