Blister packaging has become an important part of the current pharmaceutical packaging market due to its advantages of good protection, convenient use, and light weight. Blister packaging, also known as PTP packaging, is mainly composed of two parts, namely a plastic hard sheet with blisters and aluminum blister foil.
Blister packaging is a common form of pharmaceutical packaging, which has the advantages of high barrier properties, less interference between the packed tablets or capsules, and good hygiene. Among the performance indicators of blister packaging, heat sealing strength is one of the most important items, and its strength directly affects the quality of blister packaging.
Pharmaceutical PTP aluminum foil is non-toxic, odorless, light in weight, has excellent shading properties, high moisture resistance and barrier properties. It can be divided into hard aluminum foil and soft aluminum foil. The former is mostly used for the blister packaging of tablets and capsules, while the latter is generally used for the outer packaging of powder granules and powder composite flexible packaging.
The blister aluminum foil is generally made of aluminum alloy, which has excellent mechanical properties and pinhole properties, and its roughness and gloss are better than pure aluminum foil, which is beneficial to printing and decoration.
With the development of the pharmaceutical industry, the quality requirements for medical aluminum foil are getting higher and higher. For example, as the types of printing colors increase, the surface quality requirements of pharmaceutical aluminum foils are getting higher and higher. With the increase in the speed of coating and coloring equipment, higher requirements have been placed on the mechanical properties of aluminum foil for pharmaceutical packaging.

8021 aluminum foil plays a key role as a barrier material. 8021 aluminum foil has excellent electrical conductivity and light-shielding properties, high moisture resistance, gas barrier properties and odor retention properties, which can block any gas, water vapor and light, and can effectively protect the packaged objects.
The medicine blister package made of it has the advantages of good protection performance, small storage space, low cost, light weight and convenient carrying, and is one of the widely used medicine packaging forms at present.
8011 medicinal aluminum foil is one of the most promising pharmaceutical packaging materials at present. As a sealing material sealed on a hard plastic sheet, it has high cupping value, high heat sealing strength, no holes, good sealing, and strong light-shielding properties.
