Alu foil specifications for blister packaging machines

Alu foil material composition

Alu alloy: 8011 pe 8021 aluminum alloys are commonly used.

Ita: Soft (O) or hard temper, depending on the requirements (lid foil is usually hard tempered).

Alu foil thickness

Alu foil used in blister packaging machines is usually between 0.02mm and 0.075mm thick. For example, PTP aluminum foil is commonly 0.02mm to 0.035mm thick, while some special-purpose aluminum foils, such as tropical blister packaging aluminum foil, may be 0.04mm to 0.075mm thick. The thickness of the aluminum foil is mainly affected by factors such as the depth of the blister, the strength of the packaging material, the sealing requirements, and the cost. The deeper the blister depth, the thickness of the aluminum foil may need to be appropriately increased to ensure the strength and sealing of the package.
Standard thicknesses include: 20 µm aluminum foil, 25 µm aluminum foil, ma 30 µm aluminum foil. Thicker foils provide better barrier properties, but may affect flexibility.

Blister packaging machine aluminum foil width

The aluminum foil width used by blister packaging machines has a wide range, generally between 50mm and 260mm. The specific width depends on the model of the packaging machine and the size of the packaged product. The width of the aluminum foil is mainly affected by factors such as the packaging machine mold, the shape and size of the product, and the packaging efficiency. Choosing the right aluminum foil width can ensure that the packaging machine can operate stably and efficiently during the production process.

Blister aluminum foil lamination/coating structure

Heat seal coating: The side of the foil that contacts the product usually has a heat-sealable lacquer (such as vinyl, PVC or polyvinyl chloride). This allows for sealing with the forming film (usually PVC, PVDC or cold-formed aluminum).
Primer coating: A primer layer can be applied to the outside for better print adhesion.
Protective coating: An additional lacquer or protective layer can be applied to enhance scratch resistance.

Aluminum foil material and performance

Common materials: The aluminum foil used by blister packaging machines mainly includes 8021 pepa alumini, 8079 pepa alumini, ma isi. These aluminum foil materials have the advantages of high cupping value, high heat sealing strength, no holes or pinholes, and good sealing, which are very suitable for packaging sensitive products such as medicines.
Performance requirements: The material and performance selection of aluminum foil are mainly affected by factors such as the nature of the packaged product, shelf life requirements, and storage conditions. For example, for medicines that need to be stored for a long time and have high requirements for sealing, it is necessary to select an aluminum foil material with high sealing and strong heat sealing strength.

Blister aluminum foil specification example

DPH-90 aluminum-plastic blister packaging machine: The PTP aluminum foil used by this model has a width of 50-105mm and a thickness of 0.02mm.
DPP-260D Flat-Panel Aluminum Plastic/Aluminum Blister Packaging Machine: The PTP aluminum foil used in this machine is 260mm wide and between 0.02-0.035mm thick (the specific thickness may vary depending on the product).

Tensile Strength and Elongation

The aluminum foil used for blister packaging requires sufficient tensile strength to prevent tearing or breaking during processing. The elongation is usually between 1% ma 3%.

Blister Foil Printing

The aluminum foil can be printed with the required information, such as batch number, logo or drug details. It should have good solvent or UV ink printability and adhere well to the primer or lacquer layer.

Blister Foil Processability

The aluminum foil should have a smooth surface to ensure proper feeding, cutting and sealing in the blister packaging machine. Consistent thickness and good unwinding performance are important to avoid machine interruptions.

Blister Foil Barrier

Moisture Barrier: High barrier to water vapor, oxygen and light to protect sensitive drugs. WVTR (water vapor transmission rate): should be low, usually less than 0.01 g/m²/24h. OTR (oxygen transmission rate): should be close to zero to prevent oxygen from entering.

When choosing the specifications of aluminum foil, you need to fully consider factors such as the model of the packaging machine, the nature of the packaged product, and the packaging requirements. Different models of blister packaging machines may have different requirements for the specifications of aluminum foil, and the storage and use conditions of aluminum foil also need to be paid attention to to avoid the performance degradation or damage of aluminum foil due to moisture, oxidation, ma isi. The specific selection needs to be comprehensively considered according to the actual situation.
