Classification of Aluminum Foil for Pharmaceutical Packaging

Aluminum foil plays a pivotal role in pharmaceutical packaging, offering a combination of protection, sifat penghalang, dan kemudahan penggunaan. This article explores the various classifications of aluminum foil used in pharmaceutical packaging, memperincikan ciri-ciri mereka, aplikasi, and the unique advantages they provide, with an emphasis on common alloy information.

Overview of Aluminum Foil in Pharmaceutical Packaging

Aluminum foil is widely used in the pharmaceutical industry due to its:

• Hartanah Penghalang: Aluminum foil provides an excellent barrier against moisture, oksigen, dan cahaya, all of which can degrade pharmaceutical products.
• Sterility: It can be easily sterilized, memastikan keselamatan produk.
• Tamper-Evidence: Aluminum foil can be designed to show evidence of tampering.
• Kebolehubahsuaian: Can be printed with branding, dosage information, and other necessary details.

Types of Aluminum Foil for Pharmaceutical Packaging

1. Kerajang Aluminium Lepuh (Bubble Foil)
