How to Turn Aluminum Sheet into Aluminum Plastic Lid

Aluminum-plastic lid is the most widely used inner packaging material in today's pharmaceutical packaging. It is composed of aluminum alloy plate and plastic parts. It has good moisture-proof, fresh-keeping and anti-theft characteristics. It is widely used in pharmaceuticals, health products, cosmetics and other industries.

Although the aluminum-plastic combination cover does not directly contact the medicine, as a part of the medicine packaging container, the quality, safety and performance of the aluminum-plastic combination cover are very critical, which is directly related to the quality, validity period and use experience of the medicine.

The quality of the aluminum-plastic cap has a very important impact on the quality of the medicine. If the aluminum-plastic itself does not meet the relevant quality standards and has quality problems, it is easy to cause oxidation, hydrolysis, photosensitivity and other reactions of the medicine, thereby affecting the efficacy and safety of the medicine.

Alloys of aluminum sheet for Al-plastic caps

Medical aluminum-plastic caps are mainly made of aluminum alloy (8011 aluminium foil) and plastic materials (polypropylene PP), which are processed into medical bottle caps through special processes. As medical bottle caps, aluminum-plastic caps have various specifications and are easy to open. They are widely used in medicine. In the sealing of bottled liquids such as antibiotics, injections, oral liquids, and infusions, aluminum-plastic combination bottle caps also play their unique advantages.

What are the precautions for aluminum-plastic cover processing?

1. The plastic material selected for medical aluminum cover should be oil-resistant and water-resistant, with good corrosion resistance and light resistance, and will not deform or fade after steam sterilization at 120°C for 30 minutes (or steam sterilization at 130°C for 5 minutes), and has good secondary heat sealing performance. Polypropylene is usually used.

2. The aluminum-plastic cover for oral liquid should be made of aluminum alloy. It needs to be cleaned after stamping to remove the lubricating oil and dust applied to the aluminum during the stamping process. Even the anodized cover should be cleaned and dried with ionized water after entering the factory, and then enter the clean room through the conveying mechanism.

3. It should be emphasized here that the cleaned aluminum cover and injection-molded plastic cover should not be touched by hand during the entire process from entering the clean room to entering the box after molding to prevent contamination.

4. During the stamping process of the oral liquid aluminum-plastic cover, if the breakpoint type or notch type is used, the size of the breakpoint and the depth of the notch should be checked to ensure the stability of the tearing force.

5. During the anodizing process of the medical aluminum cover, attention should be paid. If the pickling time of the aluminum cover is too long, the thickness of the medical aluminum cover will become thinner, the strength will decrease, and it cannot be used.
