Flaps used to form joints can be on the end pieces or the body or both. End panels are attached to the body with special equipment, and six or more joints must be sealed to set up the box before it is filled. Once the six or more joints are sealed, the box is solid.

  • Slotted Box - The slotted box style is generally made from one piece of corrugated or solid fiberboard. The blank is scored and slotted to permit folding. The box manufacturer forms a joint at the point where one side panel and one end panel are brought together. When the box is needed, the box user squares up the box, inserts product and closes the flaps.
