Alu-Alu blister packs offer a virtual barrier for water and oxygen. However, the elongation forming process may cause pinholes, pores, and fractures, which result in the oxidation of medicine. Thus, installation of the online pinhole detector in the Blister Packaging Machine is very important for ensuring a flawless blister pack and drug safety

Medicine packed in blister machine has different requirements for barrier for water and oxygen. Alu-alu blister pack is typically used for medicines requiring excellent barrier properties. The moisture vapor transmittance (MVTR) of alu-alu blister packs is virtually zero, nearly complete barrier for water and oxygen.
Alu-alu blister pack adopts aluminum-based laminate film as the forming material, in the blister machine’s forming station, aluminum film is simply pressed into a mold by means of a stamp. The aluminum will be elongated and maintain the formed shape. In the industry these blisters are called cold form foil (CFF) blisters. With the improvement of aluminum foil rolling technique and control accuracy, aluminum foils with thickness of more than 20-25 Micron can be considered as having no pinholes and fractures.But aluminum films are vulnerable to cracks when going through the elongation forming process on the blister packaging machine; or even if aluminum films are free of fractures, they may have tiny pores that are invisible to the naked eye, with a typical diameter of less than 100 Micron
