Medicinal strip foil refers to aluminum foil used to package tablets, capsules, or other forms of medication. It is typically a specially designed aluminum foil that effectively protects medications from moisture, light, and other external factors, thus extending their shelf life. This foil is commonly used to create various forms of unit-dose packaging, such as blister packs for tablets or capsules. It can also be used to package medications in the form of patches or bubble packs for convenience and accuracy during patient administration.
