Clamshell Container Filling


Protect Products and Enhance Visibility

Rigid containers such as clamshells provide an ideal packaging format for many types of products – from lettuce and other produce items to candy, snacks, and various other non-food packaged items.

The hard-sided containers provide protection for potential fragile products, such as hydroponic lettuce leaves or fresh fruit. The barrier they create also allows for simple gas flushing and other processes designed to protect food products.

The containers also allow for excellent product visibility on store shelves, with end users able to easily identify the products inside, and the stackable design makes them easy to stock and store.

Full Automation Saves More Labor

Rigid containers also lend themselves well to additional automation beyond just the weighing and filling process.

A clamshell packaging line can easily include an automatic denester to dispense containers, and additional equipment for top sealing, lidding and closing, and even product labeling.
