Aluminum Plastic Combination Cap

Aluminum Plastic Combination Caps are widely used in the pharmaceutical industry as a packaging solution. They combine the advantages of aluminum and plastic to ensure long-term stability and safety of drugs. These caps typically consist of an aluminum part and a plastic part, providing excellent sealing performance and tamper-proof features. The aluminum part offers a strong protective layer, effectively preventing the entry of external air and moisture, thereby extending the shelf life of the drug. The plastic part facilitates user opening and use while maintaining overall lightness and cost-effectiveness. The design of Aluminum Plastic Combination Caps not only ensures effective protection of the drug but also meets the requirements of automated production lines, enhancing production efficiency and consistency.

Aluminum Plastic Combination Cap: a reliable guardian for drug packaging
Aluminum Plastic Combination Cap is a widely used material for drug packaging, especially for drugs that require high sealing and safety, such as infusion bottles, vaccine bottles, injection bottles, etc. It combines the advantages of aluminum and plastic materials, with good sealing, mechanical strength, corrosion resistance, and easy opening, becoming an important guarantee for the safe storage and use of drugs.
Aluminum Plastic Combination Cap usually consist of an aluminum inner plug and a plastic outer cover:
Aluminum inner stopper: Aluminum inner stoppers are usually located inside the plastic outer cover, with good sealing and mechanical strength, which can effectively protect the purity and safety of the medicine inside the bottle. Aluminum covers are usually designed with a part that is easy to tear or break, making it convenient to open when in use.
Plastic outer cap: The plastic outer cover is located on the outside of the aluminum cover, directly in contact with the bottle mouth, and has good elasticity and sealing properties. It can be tightly combined with the bottle mouth to prevent leakage.

The Aluminum Plastic Combination Cap is an environmentally friendly packaging solution. Its use of aluminum and plastic materials means that the packaging can be easily recycled, reducing waste that would otherwise harm the environment. Additionally, the packaging is lightweight, which reduces the carbon footprint during transportation and lowers shipping costs.

Material Advantages

The Aluminum Plastic Combination Cap utilizes a blend of aluminum and plastic. The aluminum part offers robust strength and stability, with a tensile strength of 120MPa, ensuring the cap maintains structural integrity in various environments. The plastic section provides superior flexibility and sealing; tests show it can prevent leaks for 24 hours under 0.2MPa pressure, guaranteeing product sealing.

Excellent Insulation

Aluminum's low thermal conductivity effectively blocks heat transfer. The 0.5mm thick aluminum layer in this combo cap reduces heat transmission by over 70%. When filled with hot liquids, it prevents hand burns, ensuring user safety.

Strong Corrosion Resistance

Aluminum forms a dense oxide film in air, offering strong corrosion resistance. The plastic part also shields the internal liquid from external corrosion. Salt spray tests show that after 500 hours in a 5% salt solution, the cap's corrosion area is only 0.5%, significantly lower than the 10% of standard caps, extending product lifespan.

Lightweight Design

Combining aluminum and plastic lightens the cap's weight by 30% compared to all-metal versions. This reduces packaging costs and facilitates transportation and storage, enhancing logistics efficiency.
