We see various containers and bottles with attractive caps and closures protecting the materials inside them. The most reliable and durable caps and closures are made of metal. These metal caps and closures serve as an ideal option in various industries, safeguarding the essential materials in the containers.
So, let’s take a look at the types and functions of these revolutionary caps and closures made with metal.
Understanding Metal Caps and Closures
Metal caps and closures are the seals that are used to lock containers such as jars, bottles, and other containers and protect the food or liquid inside them. They are made from metal materials such as steel or aluminum and offer several advantages, including temperature tolerance, resistance to fracture from impact, and a wide range of chemical compatibility.
How are Metal Caps and Closures Made?
Metal closures and caps are typically manufactured using different processes. Some common steps include:
- Material Selection: It includes selecting the appropriate metal material for the caps and closures, such as steel and aluminum.
- Forming: This metal material is formed into the desired shape using various techniques and applying pressure to the metal to shape it into the desired form.
- Finishing: This process enhances the appearance and functionality of caps and closures. This may include polishing, coating, or plating to provide a smooth and attractive surface.
- Lining: this process ensures a secure seal and prevents leakage. Liners can be made from materials such as foam, rubber, or plastic.
- Assembly: Once the individual components are ready, the caps and closures are assembled. This may involve attaching additional features such as tamper-evident bands or child-resistant mechanisms.
Benefits of Metal Caps and Closures
the caps and closures made with metal offer several benefits such as:
● Durability
Metal caps are known for their durability and resistance to fracture from impact. They are less prone to breaking or deformation, making them ideal for long-term storage where product integrity is critical.
● Visual Appeal
Metal closures and caps can provide attractive visual appeal, adding a tempting look to the packaging. Many brands use special colors and designs on their metal cap packaging to attract consumers.
● Security
Metal caps and closures contribute to strong sealing capabilities, helping to maintain product freshness and prevent spoilage. In this context, ROPP metal caps are widely used to protect the material inside the container.
● Compatibility
Metal caps are compatible with a wide range of containers, including glass and PET (polyethylene terephthalate) containers.
Are Metal Caps and Closures Recyclable?
The caps and closures made of metal are generally recyclable. Metal materials like steel and aluminum are highly recyclable; hence, metal caps and closures are made with these materials. To recycle metal caps, metal caps should be separated from their containers for proper sorting and processing during recycling. Some sources suggest storing them in a steel food can and crimping them closed. Metals are valuable recyclable materials, and metal recyclers often accept and pay for metal lids and caps.
To promote the recycling of these products, ALUPRO, in partnership with British Glass and the European Aluminium Foil Association (EAFA), has launched the “You Can Leave Your Cap On” campaign to increase the recovery of aluminum caps and closures for recycling. The initiative aims to encourage recyclers to screw the caps back on empty bottles before recycling them.
