Medicinal Aluminum-plastic Composite Cover

pharmaceutical industry. The following is a detailed analysis of their characteristics:
Structure and Materials
Structure: The medicinal aluminum-plastic composite cover is composed of aluminum foil and plastic layers. The aluminum foil layer is usually on the outside and mainly plays a role in oxygen isolation, moisture resistance, radiation protection, etc; The polypropylene layer on the inner side has the characteristics of good flexibility, excellent corrosion resistance, and easy molding.
Material: Commonly used aluminum foil materials have the advantages of strong tensile strength, stable torque, and good sealing performance; The inner polypropylene layer ensures good flexibility and corrosion resistance.
Specifications and dimensions
Specification: The medicinal aluminum-plastic composite cap products include different specifications such as φ 13mm, φ 15mm, φ 20mm, φ 28mm, and φ 32mm to adapt to drug bottles of different diameters.
Size: Taking the 28mm (butyl rubber stopper specific) aluminum-plastic composite cap as an example, the inner height of the aluminum cap should be 28.60 ± 0.05mm, and the thickness of the aluminum cap should be 0.20 ± 0.02mm. These precise dimensions ensure a tight fit with the drug bottle.
Characteristics and advantages
Sealing performance: The medicinal aluminum-plastic composite cover has excellent sealing performance, which can effectively prevent contamination and leakage of drugs during storage and transportation.
Antibacterial properties: Its structure and material characteristics make the medicinal aluminum-plastic composite cover have antibacterial function, which can maintain the purity of the drug.
Stability: In high temperature and humid environments, the medicinal aluminum-plastic composite cover can still maintain stable performance, ensuring the safety of drugs.
Easy to open: Through reasonable design, the medicinal aluminum-plastic composite cover is easy to open, reducing contamination of the drug during use.
Environmental friendliness: The medicinal aluminum-plastic composite cover can be recycled and reused, meeting environmental protection requirements.
