A sheet of corrugating material pressed into the wave shape known as flutes.
A configuration of steel blades used to cut material in the same shape over and over again, like a cookie cutter. When purchasing corrugated boxes, a cutting die charge will often be included that allows for the one-time purchase of these dies that can then be re-used for subsequent orders.
The act of cutting raw material (such as containerboard) to a desired shape (such as a box blank) by using a steel die. Also used to describe the resulting piece or box blank.
The three measurements of a box, given in the sequence of length, width, and depth. Inside dimensions are used to assure proper fit around a product.

A general term describing combined paperboard (corrugated or solid) used to manufacture containers.
Extensions of the sidewall panels that close a box. Flaps are usually defined by one score line and three edges. When folded and sealed with tape, adhesive or wire stitches, flaps close the remaining openings of a box. Regular slotted containers have eight flaps.
A machine that, in one operation, prints, scores, slots, and folds a box blank, and then glues the side seam (manufacturer’s joint) to complete the manufacture of a knocked down flat (KDF) box. The KDF boxes are collected at the end of the FFG and bundled to stack on a pallet for shipment to the customer.
A type of rotary printing using flexible plates and fast-drying, water-based inks. Ink is applied to a print plate, which then transfers the ink to the material like a stamp. A separate print plate is required for each color in a given design.
One of the wave shapes pressed into corrugated medium. A, B, C, E and F are common flute types, along with a variety of much larger flutes and mini-flutes.
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.”
Full-color images are created by four halftone plates, using the four subtractive primary colors: cyan, yellow, magenta, and black.
Materials or parts used to support, position, or cushion an item within a shipping container, to support the corners or top of the container, or to fill voids.
The part of the box where the ends of the scored and slotted blank are fastened together by taping, stitching, or gluing.
Word of German origin meaning strength; designates pulp, paper or paperboard produced from wood fibers by the sulfate process. Often used to describe a brown paper surface.
A separate slip or sheet of paper affixed to a surface for identification or description.
A printed sheet of paper laminated to and covering the entire surface of the box blank. Usually used to add fine-screen, four-color illustrations that cannot be achieved with direct printing on the porous paperboard surface.
A printed sheet covering a portion of the surface of the box blank. May cover a portion of one panel, a full panel, or several panels of the box.
A creased sheet inserted as a sleeve in a container and covering all side walls. Used to provide extra stacking strength or cushioning. Also used as short hand for “linerboard”.
An uncoated linerboard of two or more layers that has a white surface of either bleached fibers or cleaned recycled white fibers. The layers below the top layer are generally unbleached or recycled fibers.
A shipping container used to overwrap or contain several individual containers.
Burst strength of the combined facings of the corrugated box.
A printing technique in which the inked image is transferred from the plate to a clean cylinder, which in turn transfers the image to the sheet of paper or paperboard. The term is usually combined with the printing method, as in offset lithography; the printing process used to print lithographic laminated labels.
A design feature wherein the top and/or bottom flaps of a box do not come together, instead they extend one over the other. The amount of overlap is measured from flap edge to flap edge.
A corrugated or solid fiberboard sheet, or sheet of other authorized material, used for extra protection or for separating tiers or layers of articles when packed for shipment. (See also: Slip Sheet)
Securing and loading containers on pallets for shipment as a single unit load, typically for handling by mechanical equipment.

A set of slotted corrugated, solid fiberboard or chipboard pieces that interlock when assembled to form a number of cells into which articles may be placed for shipment.
A web (roll) of linerboard that has been printed and re-wound prior to the manufacture of combined board. Use requires special equipment on a corrugator to assure precise slit, score, and cut-off operations.
In Flexographic printing, refers to the photopolymer plate that is used to transfer a single color of ink to the material, like a stamp. Designs with multiple colors require multiple print plates.
Packaging materials that may be processed through a number of treatments or changes in order to be reused.
Corrugated, paperboard and paper may contain up to 100% recycled fibers. Fiber may be recycled from pre-consumer sources (box plant scrap and trimmings) and/or post-consumer sources (corrugated boxes that have been used and recovered for recycling).
A well-defined impression or crease in corrugated or solid fiberboard made to position and facilitate folds.
A sheet of corrugated fiberboard with one or more score-lines, slots or slits. A scored and slotted sheet may be further defined by the pattern of score-lines and slots or slits, as a box blank (for a box style made from a single sheet of corrugated fiberboard), a box piece or part, a tray or wrap, a partition piece, an inner packing piece or some other designation.
A container that is sufficiently strong to be used in commerce for packing, storing and transporting commodities.
A flat sheet of material used as a base upon which goods and materials may be assembled, stored, and transported.
The maximum compressive load a container can bear over a given length of time, under given environmental / distribution conditions, without failing.
A cut made in a fiberboard sheet without removal of material. Slit-Score: A cut made in a fiberboard sheet extending through only a portion of the thickness.
A wide cut, or pair of closely spaced parallel cuts, including removal of a narrow strip of material, made in a fiberboard sheet, usually to form flaps and permit folding without bulges in the corners.
Metal fasteners used to seal the joint of a box or close the flaps. Staples are preformed, and the tines are closed as they pierce the box. Stitches are machine-formed using wire drawn from a spool.
Used alone, the word refers to the bursting strength of linerboard or combined board, where that is the applicable measure of strength.
Detailed descriptions of the methodology agreed upon by recognized organizations.
A sheet of combined board, scored and folded to a multi-sided form with open ends. It may be an element of a box style or a unit of interior packing that adds protection and compression strength.
