Composition and structure of blister foil

Blister foil is usually composed of multiple layers, combining aluminum with other materials to enhance performance:

Blister foil aluminum layer

Usually hard tempered aluminum (AA 8011, AA 8021 or AA 8079) acts as a barrier to light, mākū, oxygen and contaminants and can be soft or hard tempered depending on the application. Typically 20µm to 30µm thick
