Die struktuur van Alu Alu blisterfoelie, ook bekend as Aluminium Cold Forming Blister Foil, is ontwerp vir die verpakking van hoogs sensitiewe farmaseutiese en generiese medisyne wat higroskopies is (moisture-absorbing) 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, vog, and oxygen, 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.

Die 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, vog, and oxygen, 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.

Alu-Alu blister packaging typically consists of three layers:

Outer Layer (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.
Inner Layer (45-mikron aluminiumfoelie): 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. In sommige gevalle, 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.
