Aluminum foil for suppository packaging is a special packaging material for suppository drugs. Its main purpose is to protect drugs from moisture, oxygen, light and microorganisms, and maintain the stability and effectiveness of drugs. It is usually used in the pharmaceutical industry to meet the high standards for drug packaging.
The main material of aluminum foil for suppository packaging is aluminum alloy. Generally, high-quality aluminum foil substrates (such as 8011, 8021, 8079 and other alloys) are selected. These materials have good ductility, formability and corrosion resistance, and are suitable for sealed packaging of drugs. In addition, aluminum foil can be used as an ideal barrier material to effectively prevent the influence of moisture, air, microorganisms, light, etc. on drugs, thereby protecting the stability and effectiveness of drugs.
The structural design of aluminum foil in suppository packaging is usually divided into the following layers:
Aluminum foil layer: It has excellent barrier properties and can effectively prevent gas and moisture penetration.
Coating layer: The surface of the aluminum foil is coated to make its surface smooth and flat, which is convenient for printing and sealing, and at the same time enhances its wear resistance.
Heat-sealing layer: By applying a hot-melt coating, a strong heat-sealed bond is formed between the aluminum foil and other packaging materials (such as PVC, PE, etc.), thereby achieving an airtight closure.

Advantages of composite aluminum foil for suppositories:
1. Excellent barrier properties: effectively isolate oxygen, moisture, light, and protect drug stability.
2. Strong heat sealing: ensure packaging sealing and extend the shelf life of drugs.
3. Good physical stability: high rigidity, tear resistance, and protect internal drugs from damage.
4. Environmental protection and safety: recyclable, in line with medical packaging hygiene standards.
5. Convenience: supports single-dose packaging, easy to carry and use.
6. Reduce costs: easy to process and recycle, reducing production costs and environmental burden.
Production process of aluminum foil for suppository packaging:
Aluminum foil rolling: The aluminum billet is rolled into aluminum foil of the required thickness through multiple rolling processes.
Surface treatment: The aluminum foil is cleaned, dried and coated to ensure that the surface of the aluminum foil is clean and suitable for subsequent processing.
Heat seal coating: Heat seal coating is applied on one side of the aluminum foil to enhance the sealing and durability of the aluminum foil.
Printing and lamination: According to customer needs, surface printing is performed to facilitate product identification; then the aluminum foil is laminated on the suppository packaging material.
Application scenarios:
1. Medical suppositories: such as antibacterial suppositories, analgesic suppositories, antipyretic suppositories, etc.
2. Health care suppositories: used for health care suppositories to prevent product ingredients from being oxidized and deliquesced.
3. Children's suppositories: Children's medicines that are sensitive to the environment require packaging materials with high safety and sealing properties.
