Which aluminum foil is better for pharmaceutical packaging?

Compared with pressure-sensitive aluminum foil, heat-sealed induction aluminum foil is usually more suitable for pharmaceutical packaging, mainly for the following reasons:
Better sealing performance
Heat sealing induction aluminum foil: Heat sealing induction aluminum foil through the heat sealing process and drug packaging containers (such as PET bottles, blister packaging of hard sheets, etc.) closely combined, can form a high-strength sealing structure, can effectively prevent air, water vapor, microorganisms and other external factors into the packaging, better protect the stability and quality of drugs, especially suitable for moisture-proof, anti-oxidation requirements of drugs.
Pressure sensitive aluminum foil: by pressure sensitive adhesive to achieve sealing, sealing strength is relatively low, long-term storage or in complex environments, may appear loose sealing, resulting in increased risk of moisture and deterioration of drugs.
Better barrier properties
Heat sealing induction aluminum foil: The overall structure formed after heat sealing is more continuous and complete, without gaps or weak points that may be caused by factors such as adhesive layer, which can more effectively block light, gas and water, and provide more reliable protection for drugs sensitive to light, humidity and oxygen, such as some biological products and vitamin drugs.
Pressure-sensitive aluminum foil: In high humidity and other environments, the viscosity of the pressure-sensitive adhesive may change, affecting the fit degree of the aluminum foil and the packaging, and thus reducing the barrier performance.
Higher health safety
Heat sealing induction aluminum foil: During the heat sealing process, high temperature can play a bactericidal role to a certain extent, reducing the possibility of microbial contamination inside the packaging. And the heat sealing process is relatively simple, does not need to add a large amount of additional adhesives and other substances, reducing the risk of chemical migration to the drug.
Pressure sensitive aluminum foil: pressure sensitive adhesive may contain some chemicals, in the long-term storage process, there is a potential risk of migration of these substances into the drug, affecting the health and safety of the drug.
Facilitate automated production
Heat-sealing induction aluminum foil: The heat-sealing process is easy to achieve automatic operation, and in the large-scale production process of drugs, it can be well matched with the high-speed packaging production line, improve production efficiency and ensure the consistency of packaging quality.
Pressure sensitive aluminum foil: On automated production lines, more processes and equipment may be needed to ensure the sealing effect of pressure sensitive aluminum foil, and the production efficiency is relatively low.
