Rigid Boxes

A rigid box style includes three pieces:

  • Two identical end panels that folds to form the two side panels
  • An unbroken bottom
  • The top panels

Flaps are used to form the joints of the box and can be on the end pieces or the body or both. The end panels are attached to the body with special equipment. The name comes from the fact that once the six or more joints are sealed, the box is “rigid”.
