Pill packaging is mainly composed of aluminum foil and a layer of plastic film (usually polyethylene or polypropylene), which are combined together by heat sealing or cold sealing technology to form small blisters, each of which contains a pill.

The aluminum foil used in pill packaging usually adopts a specific aluminum alloy to meet the needs of pharmaceutical packaging. Common alloy numbers mainly include 8011, 8021 and 8079 aluminum alloys, with a thickness range of 0.02mm~0.025mm. It adopts H18 full hard state, has high strength and hardness, and is mainly used for PTP blister packaging.

What is the role of aluminum foil in pill packaging?

1. Avoid damage to drugs: Drugs are susceptible to light, oxygen and moisture, which may cause degradation and failure, and require sealed packaging.

2. Advantages of aluminum foil: Aluminum foil has good antioxidant, moisture-proof and light-proof properties, which is suitable for drug packaging to ensure quality and safety.

3. Prevent deformation: Aluminum foil has good strength and toughness, which can prevent drugs from being squeezed and deformed during transportation and storage, and maintain the shape and quality of drugs.

4. Heat insulation: Good heat insulation performance, protects the active ingredients of pills, maintains their effectiveness, and is suitable for low-temperature storage.

5. Convenient sealing and identification: It can be heat-sealed or cold-sealed to ensure sealing, prevent pollution, and improve packaging recognition.

6. Anti-counterfeiting and protection: Use special printing and anti-counterfeiting technology to ensure the authenticity of drugs and protect consumer rights.

Quality standards for medicinal aluminum foil packaging:

1. Appearance quality: The surface of the aluminum foil should be clean, flat, free of cracks, scratches, bubbles and other defects.

2. Mechanical properties: The aluminum foil should have sufficient strength and toughness to meet the needs of packaging and transportation.

3. Chemical properties: The aluminum foil should meet the relevant chemical performance standards to ensure that it will not cause pollution or impact on the drugs.
