Struktur Alu Alu blister, Ogé dikenal salaku aluminium, dirancang pikeun jaket obat anu sénsitip sareng generik pungkur anu hygroscopic (Uap-nyerep) or light-sensitive and cannot be suitably packed with barrier plastic films. This type of foil is specifically engineered for cold forming, which is a process used to create blister packs for pharmaceutical products.

The Alu Alu blister foil typically consists of two layers of aluminum foil laminated together. Each layer of aluminum foil provides a high barrier against light, kalembaban, jeung oksigén, which is essential for protecting sensitive pharmaceutical products. The foil is also coated on one side to allow for heat sealing during the blister pack formation process.

Benang alu bieu typically consists of three layers:

Lapisan luar (25-micron PVC film): A layer of aluminum foil that is coated with a heat-sealable layer. This layer is usually the one that is heat-sealed to form the blister pack.
Lapisan Batin (45-aluminium foil mikron): Another layer of aluminum foil that provides additional barrier properties and strength to the blister pack.

The exact thickness and composition of Alu Alu blister foil may vary depending on the specific requirements of the pharmaceutical products being packaged. Dina sababaraha kasus, Alu Alu blister foil may be replaced by a structure containing special polyester film and soft aluminum foil. This new structure is composed of 36 micron special polyester / 50 micron soft aluminum foil / 36 micron special polyester composition, providing an alternative to traditional Alu Alu laminates for pharmaceutical packaging.
