Medicinal packaging aluminum foil is a material with high barrier properties, moisture-proof, anti-bacteria and anti-oxidation. It is commonly used in the packaging of medicines and can also be used in food and other packaging fields.

Process flow of pharmaceutical packaging aluminum foil:

1. Aluminum foil material selection
Medicinal packaging aluminum foil should be made of high-quality aluminum foil materials that comply with relevant national standards, such as 12μm or 15μm aluminum foil. The aluminum foil should have a flat surface, no scratches, no creases, and sufficient strength and toughness. On aluminum alloys, 8011, 8021, 8079, и 1235 alloy foils are the more commonly used choices.

2.Aluminum foil cleaning
Before aluminum foil is cut and formed, it needs to be cleaned. The purpose of cleaning is to remove impurities such as oil, dust, and fingerprints on the surface of the aluminum foil to ensure the hygiene and safety of the drugs. The cleaned aluminum foil should be dried immediately.

3. Aluminum foil surface heat treatment
Heat treatment is an important step to improve the strength and toughness of aluminum foil. During the heat treatment process, the aluminum foil undergoes a cycle of heating and cooling, which can change its internal structure and improve its mechanical properties. The aluminum foil after heat treatment should be smooth, wrinkle-free and deformed.

4.Aluminum foil forming
According to the requirements of pharmaceutical packaging, the cleaned and heat-treated aluminum foil is cut into the required shape and size. During the forming process, care should be taken to maintain the flatness and cleanliness of the aluminum foil.

5.Aluminum foil sealing
The formed aluminum foil is sealed with other packaging materials to form a closed packaging system. The sealing process should ensure that the sealing area is flat, without bulges or depressions, and that the sealing strength meets the requirements.

6. Packaging quality inspection
After sealing is completed, the pharmaceutical packaging aluminum foil should be inspected for quality. Testing items include appearance testing (such as whether there are bubbles and wrinkles at the seal, и т.н.), sealing performance testing (such as whether there is air leakage), barrier performance testing (such as oxygen permeability, moisture permeability, и т.н.). If the packaging requirements are not met, it needs to be sealed again.

7.Packaging logo printing
According to the labeling requirements of pharmaceutical packaging, the label is printed on the pharmaceutical packaging aluminum foil using equipment such as a digital printer or laser printer. The content of the label should be clear and easy to read, including important information such as drug name, production date, and expiration date. В същото време, it is also necessary to ensure that the logo is bright in color, durable and does not fade.
