Both medicinal aluminum foil and medicinal polyethylene have their own applications in the field of pharmaceutical packaging, but there are some significant differences between them.

Barrier properties: The barrier properties of medicinal aluminum foil are more excellent, which can effectively isolate various harmful substances, while the barrier properties of polyethylene are relatively weak.

Heat resistance: medicinal aluminum foil has high heat resistance and can withstand high temperature and other processing processes, while polyethylene has relatively poor heat resistance.

Moisturizing performance: medicinal aluminum foil can effectively prevent the volatilization and absorption of water in the drug, while the moisturizing performance of polyethylene is relatively weak.

Corrosion resistance: medicinal aluminum foil has good corrosion resistance to most chemicals, solvents and oils, while the corrosion resistance of polyethylene is relatively weak.

In general, medicinal aluminum foil and medicinal polyethylene have their own advantages and application scenarios in the field of pharmaceutical packaging. Which material to choose depends on the specific drug characteristics and packaging needs.
