Classification of Aluminum Foil for Pharmaceutical Packaging

Aluminum foil plays a pivotal role in pharmaceutical packaging, offering a combination of protection, خواص مانع, و سهولت استفاده. This article explores the various classifications of aluminum foil used in pharmaceutical packaging, جزئیات ویژگی های آنها, برنامه های کاربردی, 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:

• ویژگی های سد: Aluminum foil provides an excellent barrier against moisture, اکسیژن, و نور, all of which can degrade pharmaceutical products.
• Sterility: It can be easily sterilized, ensuring product safety.
• Tamper-Evidence: Aluminum foil can be designed to show evidence of tampering.
• قابلیت سفارشی سازی: Can be printed with branding, dosage information, and other necessary details.

Types of Aluminum Foil for Pharmaceutical Packaging

1. فویل آلومینیومی تاول زده (Bubble Foil)
   • ویژگی:
     • Typically consists of a layer of aluminum bonded to a layer of plastic.
