Alu Base Foil for Medicine Packaging

Blister packaging is a commonly used packaging form for pharmaceutical products. The two parts of the hard sheet and the aluminium foil are heat-sealed together to form a closed space that can accommodate medicines. In view of the fact that the blisters of the blister pack are not connected, the damage of one of the blisters will not affect the sealing of the other blisters, so whether it is during the storage of the drug or after taking part of the drug, blister packaging has a good protective effect on medicines.

For foil medicine packaging, the quality is largely reflected in the heat-sealing strength of the product. Aluminum foil is the carrier of the adhesive layer, and its quality has a great impact on the heat-sealing strength of the product. Especially the surface oil of the original aluminum foil can weaken the adhesion between the adhesive layer agent and the original aluminum foil. If there is oil on the surface of the alu base foil and the surface tension is lower than 3.1×10-2μm, it will be difficult to achieve the ideal heat sealing strength, so the quality of the original aluminum foil must be strictly controlled.

The common ptp aluminum foil alloys are 8011 and 8021. The surface of 8011 aluminum foil is clean, of uniform color and free of spots and pinholes. I has strong mechanical properties, high blast resistance, strong puncture and tear resistance. Aluminum foil after compounding, printing and gluing is widely used as packaging material.

8021 aluminum foil plays a key role as a barrier material. 8021 aluminum foil has excellent electrical conductivity and shading properties, high moisture resistance, gas barrier and taste retention, which can block any gas, water vapor and light, and can effectively protect the packaged objects.

The pharmaceutical blister packaging made of it has the advantages of good protection performance, small storage space, low cost, light weight, and easy to carry, and is one of the widely used pharmaceutical packaging forms at present.

According to their different tempers of alu alu base foil, they are used on different drug packages. The O state is commonly used in the packaging of capsules, tablets, etc., and the H18 state is relatively hard and is used in the packaging of granule drugs. Initially, simple packages such as plastic and paper were used in drug packaging, but these packages are not easy to preserve, and are easy to destroy the ingredients of the drug, which greatly reduces the efficacy of the drug. Nowadays, aluminum foil medicine packaging is a good solution to the above problems for medicine packaging.
