Clamshell (container)

A clamshell is a one-piece container consisting of two halves joined by a hinge area which allows the structure to come together to close.

Containers acting similar to clamshells have been widely used for many years, constructed from a diversity of materials.

Folding cartons made of paperboard or molded pulp can also be of a clamshell shape.

When plastic clamshell containers are securely heat sealed, they are tamper resistant and deter package pilferage.

These security packages are intentionally difficult to open, sometimes requiring customers to use scissors or a knife.
