Blister aluminum foil packaging

The aluminum foil used in the blister aluminum packaging is a sealing material sealed on a medicinal plastic polyvinyl chloride (PVC) rigid sheet, so it is called a cover material. The blister aluminum foil is made of high quality aluminum raw material and is calendered. Aluminum foil for blister packaging has the advantages of odorless, conductive, light-shielding, moisture-proof, gas barrier and good taste. 8011 and 8021 aluminum foil o H18 are usually used as the base material for blister aluminum packaging.

The aluminum-plastic blister package of medicine is also called blister pack. This form of packaging has several advantages: First, it is convenient and economical to provide the patient with a single dose of the drug package. Secondly, the blister packaging has a fast production speed, low cost, small storage area and convenient transportation. Again, the safety is well, because the surface of the blister aluminum foil is printed with text, it can avoid the wrong medicine in the process of issuing a variety of tablets.

Because aluminum foil has a highly dense metal crystal structure that completely blocks any gas, water vapor and light, it can most effectively protect the packaged object, so the blister aluminum foil are used in blister packaging. In modern packaging, almost all products requiring opaque, high barrier composites use aluminum foil as a barrier. The aluminum foil pinhole affects the barrier properties, especially for pharmaceutical packaging, and it is easy to make oxygen, water vapor, and light penetrate to reduce the efficacy of the drug. Therefore, for medicinal aluminum foil, the national standard requires that there should be no pinholes with a diameter greater than 0.3 mm, and pinholes with a diameter of 0.1-0.3 mm should not exceed one per square meter.
