Blank or Box Blank- A flat sheet of corrugated or solid fiberboard that has been cut, slotted and scored so that, when folded along the score lines and joined, it will take on the form of a box.

Board- Abbreviation on various paperboards. ( Boxboard, Chipboard, Combined Board, Containerboard, Corrugated Board, Fiberboard, Linerboard and Paperboard).

Box - A rigid container having closed faces and completely enclosing its contents.

Box Certificate - The statement printed within a circular r rectangular border on a corrugated or solid fiberboard box guaranteeing that all applicable construction requirements of the carrier classifications have been observed and identifying the box manufacturer .

Box Dimensions - corrugated box, corrugated mailer and most other box measurements are always stated as inside dimensions in (L x W x H) sequence.

Boxboard - The types of paperboard used to manufacture folding cartons and set up (rigid boxes)

Built-up - Multiple layers of corrugated board glued together to form a pad of desired thickness, normally used for interior packing.

Burst Strength/Mullen - The force required to rupture linerboard or combined board, using hydraulic pressure to measured by a Mullen tester, relates indirectly to the box's ability to withstand external or internal forces, and contain the contents during rough handling.  This method cannot be used on triple wall combined board and is limited reliability on double wall, as it is difficult to force the apparatus through the multiple facings simultaneously.  When using certain specifications in the carrier classifications, minimum burst strength must be certified.

Carton (Folding Carton)- A folding box made from boxboard and normally used as container for consumer products.  A carton is not recognized as a shipping container.

Chipboard - A paperboard generally made from recycled paper stock. Applications include: partitions within boxes, backing sheets for padded paper, sample boards and the center ply or plies of solid fiberboard.

Classification, Freight - The rules and regulations governing the acceptance of freight in transportation. Includes the acceptable forms of packaging for each commodity and the specifications for shipping containers.

Combined Board - A combinations of components such as corrugated and solid fiberboard to fabricate a sheet.

Corrugated Board or Corrugated Fiberboard - Gluing one or more sheets of fluted corrugating medium to one or more smooth facings of linerboard to build  a composition. The four most commonly used are:  Single Face: One smooth facing of linerboard glued to one fluted corrugating medium.  Single Wall (Double Face): Each side of a corrugated medium has been glued to a smooth facing of linerboard.  Double Wall: 5 alternating layers; three smooth facing of linerboard and two corrugated mediums glued together. Triple Wall: 7 alternating layers; four smooth facings of linerboard and three corrugated mediums glued together.

Die Cut - The use of a die to cut corrugated or other combined board to a desired shape.

Edge Crush Resistance/Short Column Compression (ECT) - The force necessary to crush on-edge combined board is a primary factor predicting the compression strength of a corrugated box.

Facing - (inside and outside liners) linerboard sheets used as the smooth outer layer of combined corrugated board. 

Flaps - The side wall extensions that close a box.

Flute or Corrugation - The most common flute types are A, B, C, E, and F. These are the rounded (wavy) grooves glued to corrugated medium. Normally flutes run parallel to the depth of the box so that they are vertical when the box is stacked.

Full Overlap Slotted Container (FOL) - A box made with all flaps the same length (box width). The outer Flaps will come within in one inch of a complete overlap when closed. This box style is very resistant to rough handling. If the box is stacked on its bottom panel the overlapping flaps provides super cushioning. Extra stacking strength is realized when the box is stacked on its side.

Full Telescope Design Container (FTD) - This is a two piece box manufactured from two slotted and scored blanks (trays).

Half Slotted Container (HSC) - A corrugated box manufactured without a set of flaps.

Item 222 - Of the National Motor Freight Classification Rule states the requirements for corrugated and solid fiberboard box

Linerboard - The smooth flat outer facings of corrugated fiberboard or the outside plies of solid fiberboard.

Media Mailers - Specially designed corrugated containers for CD's, videos and cassettes.

One Piece Folder (OPF) -A single piece of corrugated board is cut to provide a flat bottom and the flaps form the sides and ends and the extensions of the side flaps meet to form the top or the corrugated container.

Overlap Slotted Container (OSC)- Made with all flaps having the same length with the outer flaps overlapping by one inch or more. This box style helps keep the outer flaps from pulling apart when the box's length is much greater that the width.

Panel - The "side" or "face" of a box

Paperboard - A major product of the paper industry. Includes  broad materials made of cellulose fibers, chiefly recycled paper stock and wood pulp.

Partition - The interlocking set of chipboard, solid fiberboard or corrugated pieces that form cells which items can be place for shipping.  Partitions act a cushioning and provide added stacking strength to the shipping box.

Regular Slotted Container (RSC) - The most popular corrugated box style for shipping.  A box made with all flaps being the same length and the two outer flaps (usually the lengthwise flaps) are one-half the box's width which allows them to meet at the center of the box when folded.

Score or Scoreline - The crease or impression on corrugated or solid fiberboard to make it easier to fold

Set-up Boxes - A fully assembled container where one set of end flaps have been sealed and is ready to be packed.

Sizing - During manufacturing, a sizing material is applied to the paperboard surfaces which fills pores and reduces absorption and increase the papers resistance to moisture damage.

Slot - The wide cut made to a fiberboard sheet to form flaps and allow folding. 

Solid Fiberboard - Two or more plies of containerboard laminated to form a solid board.

Surface Smoothness - The surface smoothness of linerboard my affect printing quality. Slight depressions on the surface of linerboard may not receive complete ink coverage and could also affect coefficient of friction, gloss and the absorption of coatings

UPS BOXES - Corrugated boxes designed to meet United Parcel Service's (UPS) maximum acceptable dimensions for shipping in their system. A package cannot exceed 108 inches in length or 130 inches in combined length and girth.

U-liner - Made from a single wall corrugated board in the shape of a "U".  Use as a protective cushion.

Wax Blend Surface Coated - Combined board coated on one or both sides with a hot-melt wax blend, typically applied with a curtain coater.

Wax Cascaded - Melted paraffin wax or wax blend that is poured over vertical box blanks so that the wax cascades down the corrugated flutes and the corrugated board facings.

Wax Dipped - Corrugated Board is impregnated with wax by dipping the corrugated board into a vat of molten paraffin wax or wax blend.

Wax Impregnated - Combined board having one or more components infused with a paraffin-type wax or wax blend.

Wrap Around Blank - For use on automatic equipment that wraps a corrugated blank around a rigid product creating the box.  The completed box is basically an RSC, turned on its side so the bottom and top are unbroken.  The joint is formed only at the final closure.
