Pharmaceutical aluminum foil is a special packaging material for packaging solid, liquid and semi-solid dosage forms in the pharmaceutical industry. It is an aluminum foil specially designed for pharmaceutical packaging applications and must meet certain quality and performance standards to ensure the safety, effectiveness and stability of the packaged medicines.

Pharmaceutical Aluminum Foil

Pharmaceutical aluminum foil is usually made of 8011 or 8021 aluminum alloy with a thickness ranging from 0.02mm to 0.07mm. The surface of pharmaceutical aluminum foil is usually coated with a layer of protective coating, such as heat-sealing varnish, which can improve its sealing and adhesion performance, and facilitate packaging sealing.

Pharmaceutical aluminum foil is widely used in the packaging of various dosage forms such as tablets, capsules, powders, granules, and suppositories. It is also used in the packaging of medical devices and instruments such as syringes, needles and catheters. Pharmaceutical products packaged in aluminum foil are often required to meet stringent quality standards, such as Good Manufacturing Practice (GMP) guidelines, to ensure the safety, efficacy and quality of pharmaceuticals.

Important indicators of medicinal aluminum foil

The surface of medicinal aluminum foil should be clean, flat, and evenly coated, and the text and pattern printing should be correct, clear, and firm.

1. Pinhole degree

The rolling process is used in the aluminum foil production process, and defects will inevitably occur, and pinholes are the most important one.

The size and number of pinholes in aluminum foil have a decisive influence on the moisture resistance, gas barrier and light-shielding properties of aluminum foil and its composite materials. Aluminum foil should not have dense, continuous, periodic pinholes. In each square meter, no pinholes with a diameter greater than 0.3mm are allowed, and no more than one pinhole with a diameter of 0.1~0.3mm is allowed.

Pinhole degree detection meets standard

2. Barrier performance

Measuring the barrier performance indicators of pharmaceutical packaging materials:

Oxygen transmission rate

water vapor transmission rate

The barrier performance of aluminum foil is an important indicator for selecting suitable packaging materials for pharmaceutical products. Packaging containers with excellent barrier properties can prevent drugs from absorbing moisture and active ingredients from being oxidized and deteriorated, greatly extending the shelf life of drugs.

3. Bursting strength

The ability of aluminum foil to withstand static localized extrusion in actual transportation environments.

Pay attention to the process of pharmaceutical packaging molding, transportation, storage, and sales to protect the pharmaceuticals from damage caused by external pressure and impact.

4. Heat sealing strength of adhesive layer

The thermal bonding strength between the blister and the aluminum foil is directly related to heat sealing parameters such as heat sealing temperature, heat sealing pressure, and heat sealing time.

The heat sealing strength of blister and aluminum foil is low and leakage problems are prone to occur. This means that the protective function of the pharmaceutical packaging will be completely lost due to direct contact between the medicine and the outside air, which will bring great consequences to the producers and users of medicines. risks of.

5. Adhesion of protective layer

In addition to preventing oxidation and corrosion of the aluminum foil, the protective layer on the surface of the aluminum foil can also protect the printed layer on the surface of the aluminum foil from being scratched.

The adhesion of the protective layer is poor. When it falls off during heat sealing or other heating processes, the protective effect on the ink will be weakened, so the ink layer is prone to problems such as scratching and falling off.

6. Heat resistance of protective layer

The protective layer has poor heat resistance and is prone to falling off during heating processes such as the heat sealing process.

The protective layer is laminated with the original aluminum foil and heat-sealed at 200°C. After cooling, check whether the surface of the protective layer has obviously peeled off.
