Caps and Closures 101

• The caps and closures that seal up steel drums and IBC Totes are the first and last line of defense.
• They are designed to hold in the contents of the drum or tote and to make sure that nothing unwanted gets in.
• Caps need to be strong enough to withstand the pressure of the contents, which can vary depending on the product.
• Vented closures help to extend the shelf-life of a product by allowing a slow and steady release of pressure.

The first line of defense against the forces of nature and the world

The caps and closures that seal up steel drums, IBC Totes, and jerrycans are the first and last line of defense.

They are designed to hold in the contents of the drum or tote and to make sure that nothing unwanted gets in.

These caps and closures vary in size and shape, depending on the type of drum or tote. Typical compositions are plastic or metal.

By ensuring that the caps and closures get a proper seal, the contents of the container remain safe and secure during transport and storage.

Some industrial closure systems feature a tamper-evident design to show whether the container has been opened, while others are designed to be more secure. In all cases, a cap or closure should match the specific application to make sure that it is the right fit for the job.

Non-vented caps and closures are designed to be as airtight as possible so that no contamination can occur during the transport or storage of specific materials.

Conversely, vented closures make sure things don't expand beyond a container's capacity to withstand the build-up of gasses. Strength plays a factor. Caps need to be strong enough to withstand the pressure of the contents, which can vary depending on the product.

Vented closures also help to extend the shelf-life of a product by allowing a slow and steady release of pressure. This release is particularly important when it comes to food products, as it keeps the contents fresh and prevents spoilage.

Furthermore, vented closures help to reduce the risk of contamination by preventing moisture from entering the container and contaminating the contents. Vented closures are an important part of any successful packaging and storage system.
