Containerboard

The paperboard components used to manufacture corrugated and solid fibreboard.

Corrugatedboard/Fibreboard
The structure formed by gluing one or more sheets of fluted corrugating medium to one or more flat facings of linerboard. There are four types:

    Single Face: Combination of one fluted corrugating medium glued to one flat face of linerboard.

    Single Wall: Two flat facings of linerboard, one glued to each side of a corrugated sheet.

    Double Wall: Three flat facings of linerboard with two interleaved and glued corrugated mediums.

    Triple Wall: Four flat facings of linerboard with three interleaved and glued corrugated mediums.

Corrugated Medium
A sheet of corrugating material that has been softened with steam and pressed into the shape known as flutes.

Corrugator
The machine that unwinds two or more continuous slices of containerboard from rolls, presses flutes into the sheet of corrugating medium, applies adhesive to the tips of the flutes and bonds the sheet of linerboard to form corrugated board.




Die Cut
A cut made with a die, i.e., the sharpened edge of a thin strip of steel rule mounted vertically on a wood frame The act of cutting raw material (such as containerboard) to a desired shape (such as a box blank) by using a die.

Depth
The distance measured perpendicular to the length and width.

Dimensions
The three measurements of a box, given in a sequence of length, width and depth. Inside dimensions are used to ensure proper fit around a product while outside dimensions are used in the carrier clarifications and determining pallet patterns.

Duplexed
When paper is printed on both sides of the sheet.

Fiberboard Box or Fibre Box
A shipping container made of corrugated or solid fibreboard, flute or corrugation. One of the wave shapes pressed into corrugated medium.

Flute (Corrugation) Direction
The normal direction of flutes is parallel to the depth of the box so that they are vertical when the box is stacked for shipment. In end-opening and wrap-around box styles, the flute direction may be parallel to the length and width resulting in a 'horizontal corrugation box'.




Length
Larger of the two dimensions of the open face of a box as set up to receive product.

RSC
Regular Slotted Container. It is perhaps the most common box style. All flaps are the same depth and the two outer flaps are one-half the container's width so that they meet in the center of the box when folded.

Width
Smaller of the two dimensions of the open face.
