China pharmaceutical aluminum foil manufacturers Haomei offer high quality medical aluminum foil 8011, 8021 and 8079 for pharmaceutical packaging. Among them, 8011 aluminum foil is often used as the bottom foil in pharmaceutical foil composed foil film. Haomei can process 8011 aluminum foil with thickness of 0.018-0.075mm, the specification can also be customized according to customer needs. The element content of aluminum foil 8011 for pharmaceutical packaging are: Silicon 0.50～0.90, Fe 0.60～1.0, Copper 0.10, Manganese 0.20, Magnesium 0.05, Chromium 0.05, Nickel&Zinc 0.10, Titanium 0.08, Other total 0.15 and Aluminum balance.
As we have known, aluminum foil composite film is usually used in pharmaceutical packaging, that is aluminum foil and plastic film are composited with adhesive, such as cellophane and aluminum foil and polyethylene composite (PT/AL/PE), polyester and aluminum foil and polyethylene composite (PET/AL/PE). The base pharmaceutical aluminum foil material is aluminum foil roll 8011, 8021 and 8079. While the typical laminated materials are polyester (PET), cellophane (PT) and cellophane with PVDC coating. The high barrier layer has good gas barrier properties and moisture resistance, does not penetrate bacteria and microorganisms, has good mechanical properties, has a certain elongation, is resistant to cold and heat, and is safe and non-toxic. The typical material is soft aluminum foil. However, this soft aluminum foil is opaque, does not rust itself, and has strong opacity. If a transparent strip packaging film is required, PVDC should be used as a high barrier material. PVDC is a high barrier material, and its biggest feature is its excellent barrier properties to gas and water vapor. The sealing layer is an inner layer of a strip-shaped packaging film, has excellent heat-sealing properties, and has chemical stability and safety and hygienic properties.
