8079 aluminum foil and 1235 aluminum foil are both widely used in pharmaceutical packaging due to their excellent barrier properties, good formability, and stability.

Similarities:

1. Tots dos 8079 i 1235 aluminum foils are pure aluminum with a high degree of purity and a uniform thickness.
2. Both have good barrier properties, preventing moisture, oxigen, and other gases from entering the packaging, thereby protecting the drug from oxidation and deterioration.
3. Both have excellent formability and can be easily formed into various shapes and sizes required for pharmaceutical packaging.
4. Both have excellent stability, ensuring the safety and effectiveness of the drug during storage and transportation.

Differences:

1. 8079 aluminum foil is alloyed with other elements such as iron, silici, and manganese, while 1235 aluminum foil is pure aluminum. Per tant, 8079 aluminum foil has a higher strength and better formability than 1235 paper d'alumini.
2. 8079 aluminum foil has a higher tensile strength and elongation than 1235 paper d'alumini, making it more suitable for applications that require high strength and good flexibility, such as blister packaging.
3. The surface of 8079 aluminum foil is slightly brighter than that of 1235 paper d'alumini, which is more attractive in appearance.
4. The price of 8079 aluminum foil is higher than that of 1235 paper d'alumini, mainly due to the additional alloying elements and the higher manufacturing cost.

In summary, both 8079 aluminum foil and 1235 aluminum foil have their own advantages and disadvantages in pharmaceutical packaging, and the choice should be made based on the specific requirements of the application.
