Aluminium Blister Foil

2024-06-19

Aluminium blister foil is mainly used to package medicines with the advantages of moisture-proof, oxidation-proof and corrosion-proof, which can protect the quality of medicines and prolong the shelf life of medicines. It is usually used to make tablets, capsules, granules and other pharmaceutical packaging. The quality requirements of pharmaceutical blister aluminium foil are very strict, generally requiring a smooth surface, no oil, no air holes, no impurities and so on. In addition, its physical properties such as tensile strength, tensile breaking strength, ductility, etc. also need to comply with the relevant standards. In the production process, the production process needs to be strictly controlled to ensure that the product meets the requirements of pharmaceutical packaging.

Pharmaceutical alu blister foil is a kind of aluminum foil material specially used for packaging pharmaceuticals, usually made of pure or alloyed aluminum. Common alloys include 8011, 8021, etc. The temper is H18. This alloy has excellent physical and chemical properties and is very suitable for use as a pharmaceutical packaging material. The thickness of pharmaceutical blister aluminium foil is usually between 0.016mm and 0.04mm, and the width range is usually between 100mm and 1000mm, different thickness and width of aluminum foil can meet the needs of different pharmaceutical packaging. Specific specifications can be customized according to customer requirements.

The quality standard of aluminum foil for pharmaceutical packaging mainly includes the following aspects:

Appearance quality: the surface of aluminum foil should be smooth, without obvious scratches, wrinkles, oxidation spots and other defects, and uniform color.

Physical properties: including the thickness, tensile strength, elongation at break and other indicators of aluminum foil, which are directly related to the tensile properties and wear resistance of aluminum foil.

Chemical properties: mainly refers to the chemical composition and corrosion resistance of aluminum foil, the chemical composition of aluminum foil is required to be stable, shall not contain harmful substances, and has a certain degree of corrosion resistance.

Mechanical properties: mainly refers to the bending properties and tear strength of aluminum foil, which requires aluminum foil to have certain flexibility and tear resistance in the packaging process.

Hygienic performance: mainly refers to the hygienic safety of aluminum foil, which is required not to contain harmful microorganisms and heavy metals and other substances, in line with the hygienic requirements of drug packaging.

Pharmaceutical aluminium blister foil has a wide range of applications in the field of pharmaceutical packaging. Its main structure includes protective layer, outer printing layer, aluminum foil substrate, inner printing layer and adhesive. As aluminum foil has a high degree of barrier and light-shielding properties, it can effectively prevent medicines from being affected by external factors such as air, moisture and light, and maintain the stability and effectiveness of medicines. In addition, aluminum foil also has good tear resistance and is not easy to break, which can provide better packaging protection and prevent drugs from being contaminated by external substances. At the same time, aluminum foil packaging also has a smaller volume and lighter weight, which is convenient to carry and suitable for medicines in transportation and travel.

Manufacturers of aluminium blister foil must have relevant production licenses and quality management system certification, and produce in strict accordance with relevant national standards to ensure stable and reliable product quality. At the same time, the factory products should be strictly inspected and tested to ensure the quality of the products is qualified.
