Bag-sealing machines


Stapling machines are used to close bags and packages using a metal staple applied to the end of the bag.

This packaging system is used when a simple, fast and stable closure is required, particularly common in the food sector and in the packaging of baked goods.

Stapling machines can be integrated into packaging lines to complete the final stage of closing packages after the bag has been filled.

Where are riveting machines used?

The staple closure system is mainly used for products packaged in bags that require a secure but not airtight closure.

Among the most common applications we find:

  • bread and baked goods
  • breadsticks
  • sweets and confectionery products
  • food products packaged in bags
  • individually packaged industrial items

This closing method allows the product to remain protected during handling and transport, while also ensuring ease of opening.

How the toggle fastening works

In stapling machines, the bag containing the product is positioned in the closing area where the system applies a metal staple that secures the bag material.

The staple is compressed around the bag, creating a stable and resistant closure, suitable for handling packages in the subsequent stages of the production line.

Integration into packaging lines

Stapling machines are generally used as the final stage in packaging lines, when the product has already been placed in the bag and needs to be closed quickly and securely.

Within a production line, they can be combined with other packaging technologies depending on the type of closure required.

For example, in applications where a reclosable closure with a metal clip is required, clipping machines are used, widely adopted in the packaging of baked goods such as bread and breadsticks.

When instead the package is closed by twisting the film, typical in the packaging of candies or confectionery products, twist packaging machines are used.

Stapling machines therefore represent an alternative solution for closing bags when a simple and durable closure using a metal staple is required.
