The aluminum cap is made of high-quality aluminum alloy materials. It is mainly used for medical and health care products and can meet the special requirements of high temperature and sterilization. Aluminum caps are mostly processed on production lines, with the thickness of the material specification generally ranging from 0.21mm to 0.23mm. Aluminum caps offer the flexibility of choosing different printing techniques, providing a good sealing function. Additionally, they offer more technological choices than plastic caps.
Benefits of Alu Plastic Caps
The pharmaceutical industry places a premium on product safety and the prevention of tampering. Aluminum bottle caps provide a tamper-evident seal by featuring a breakable ring or bridge that must be removed before the bottle can be opened. This ensures that the product remains secure and untouched until it reaches the end-user, enhancing consumer confidence in product integrity.
Aluminum offers excellent barrier properties against oxygen, moisture, and light. Pharmaceutical products, particularly those sensitive to environmental factors, require protection from these elements to maintain their stability and efficacy. Aluminum caps act as a reliable barrier, preserving the product's quality throughout its shelf life.
Certain pharmaceutical products, such as medications, should be kept out of the reach of children. Aluminum bottle caps can be designed with child-resistant features, making it challenging for young children to open the bottles. These features are essential for safety and regulatory compliance.
Pharmaceutical companies often seek to differentiate their products in the market. Aluminum bottle caps offer a wide range of customization options, including embossing, debossing, and printing. This allows pharmaceutical companies to brand their products effectively, convey important information, and enhance the overall aesthetics of the packaging.
As mentioned earlier, aluminum is recyclable, making it a sustainable choice for pharmaceutical packaging. The pharmaceutical industry has been increasingly focused on sustainability and reducing its environmental impact. Using aluminum bottle caps aligns with these sustainability goals.

Types of Alu Plastic Caps
A seal with a plastic Flip Off button that must be removed to expose the injection site.
Flip Off (FOT) seals are used most commonly to package parenteral drugs where it is important that the vial contents remain sterile and secure.
The Flip Off button covers the stopper and helps to keep it clean prior to use. When removed a central section of the stopper is exposed ready for needle insertion. The aluminium skirt remains in place to secure the stopper, maintaining sterility of the vial contents.
A seal with a plastic button attached to help facilitate the activation and complete removal of the seal from the container.
Flip Tear Up seals can be easily removed from the vial, allowing removal of the stopper and access to the vial contents.
Flip Tear Up seals are used for non-injectables and where needle extraction is not required. They might be used in topical, oral or ophthalmic applications.
They are available in 13mm, 20mm and 32mm sizes.

Centre Tear seals are used most commonly to seal vials containing a parenteral drug. A central section of the seal can be lifted out in order to expose a central section of the stopper beneath allowing for needle insertion.
An all-aluminium seal with Tear Out tab that allows the complete removal of the closure prior to use.
Complete Tear Seals can be fully removed from the vial by hand, allowing access to the vial contents. This solution would suit products that do not require sterility or extraction by needle. Complete Tear Seals might be used to seal vials containing diagnostic solutions, topical or oral products.
Applications of Alu Plastic Caps
1.Oral Medications Bottle caps for oral medications are often designed with tamper-evident features to ensure product safety. Aluminum's barrier properties help protect the medication from moisture and air, maintaining its effectiveness.
2.Parenteral Medications Parenteral medications, such as injectables, must be stored in airtight and sterile conditions. Aluminum bottle caps provide an effective barrier against contamination and are compatible with the autoclave sterilization process.
3.Over-the-Counter (OTC) Products Many OTC pharmaceutical products, including vitamins and supplements, utilize aluminum bottle caps for their flexibility in branding and tamper-evident features.
4.Liquid Pharmaceuticals Syrups, suspensions, and other liquid pharmaceuticals benefit from the moisture resistance provided by aluminum caps. This ensures that the product remains in optimal condition until consumed.
5.Specialty Medications Specialty medications, often biologics or high-value pharmaceuticals, rely on aluminum caps for their tamper-evident properties and robust barrier protection.
Process of Alu Plastic Caps
Production Process of Aluminum Cover
When producing caps for pharmaceutical glass vials, a punching machine is used to drive the punching die for the punching process. The die employed is a ring-cutting die, and the raw material utilized is an aluminum alloy plate, typically requiring a double coating film on the aluminum alloy.
Production Process of Plastic Cover
Lorem ipsum dolor sit amet consectetur adipisicing elit.In the production of plastic caps, a plastic injection molding machine melts plastic raw materials and injects them into a mold for the injection production process. The material for plastic caps consists of polypropylene (PP) and color masterbatch, allowing the production of various colored plastic caps based on the color of the color masterbatch.
Combined Cover Production Process
To create the aluminum-plastic combination cap for pharmaceutical glass vials, pour the aluminum cap and plastic cap onto the corresponding turntable of the heat-sealing machine for the heat-sealing process.

1. The use of high-quality aluminum material ensures hygiene, rust resistance, and easy opening without auxiliary tools. The bottle cap becomes destructible after opening, effectively preventing theft.
2. Aluminum-plastic composite covers provide excellent cushioning, shock resistance, heat insulation, moisture resistance, and chemical corrosion resistance. They are non-toxic, non-absorbent, dust-free, peel-free, and scale-free, offering a strong sealing performance.
3. Customizable features include the use of stainless steel shot for special requirements like high temperature resistance, boiling resistance, and alcohol resistance. Pattern design options include color printing, embossing, and milling.
Q: What are the sealing methods of Aluminum Caps?
(1) Side wall sealing relies on effective contact between the bottle mouth and the outer part of the bottle cap sealing system. Common pattern cap schemes, such as screw caps, use this sealing system. Glass covers for injections are typically metal covers combined with rubber stoppers, selected based on product structure, use, and price considerations.
(2) Flat pressure sealing is exclusive to screw caps. It increases the contact surface of the sealing ring between the bottle mouth surface and the inner surface of the bottle cap when tightened, achieving the sealing effect.
(3)When specifying aluminum cap specifications, it's essential to select suitable bottle caps for saline bottles of different calibers. The shape of the aluminum cap is generally a multi-position flat top, and the pressed shape depends on the capping machine's mold. If the mold and flat top are sealed into an aluminum cap flat top shape, they may not tightly attach to the bottle stopper, leading to potential loosening.
