Aluminum foil is generally used as packaging material in the pharmaceutical industry. The commonly used models are 8011 aluminum foil and 8021 aluminum foil, which are heat-bonded with various plastic substrates to make packaging for packaging pharmaceutical tablets, capsules, pills, etc., with good Excellent airtightness, ultra-high barrier properties, excellent light-shielding properties, excellent mechanical properties, heat resistance, low temperature resistance, corrosion resistance and other characteristics.
With the development of the packaging industry, the packaging of health food, pharmaceutical tablets, and capsules is becoming more and more common in the form of blister packaging. It is one of the pharmaceutical packaging materials with good development prospects at present, and the share of aluminum foil used in pharmaceutical packaging is also increasing every year. higher. So what is the difference between 8011 aluminum foil and 8021 aluminum foil?
1. The ingredients are different. 8011 aluminum foil contains Mn and Mg elements, but 8021 aluminum foil does not contain these two elements, so the strength and corrosion resistance of 8011 aluminum foil are higher than 8021 aluminum foil. PTP pharmaceutical aluminum foil alloy usually adopts 8011-H18 state aluminum foil, 8011-O state aluminum foil, etc., with a thickness of 0.016-0.04mm.
2. The performance is different. 8011 aluminum foil has high strength, but the corresponding elongation and puncture resistance under the same state are lower than 8021 aluminum foil. In pharmaceutical packaging, the aluminum foil coating on the back of the medicine capsule is mostly 8021 aluminum foil. 8021 aluminum foil and 8079 aluminum foil are mostly used for blister aluminum and tropical aluminum with higher rate requirements.
3. The scope of application is different. 8011 aluminum foil is more widely used, not only can be used as medicinal aluminum foil, but also can be used in many fields such as food packaging, lunch box material, tape foil, cable foil, milk cap material, bottle cap material, etc. 8021 aluminum foil is mostly used in the packaging of lithium battery soft-packed aluminum-plastic film and blister medicine.
4. The prices are different. The price of 8021 aluminum foil is relatively higher.
