Glossary Corrugating Medium: The type of paperboard used in forming the fluted portion of corrugated board. Corrugation: (See: Flute) Corrugator: The machine that unwinds two or more continuous sheets of containerboard from rolls, presses flutes into the sheet(s) of corrugating medium, applies adhesive to the tips of the flutes and affixes the sheet(s) of linerboard to form corrugated board. The continuous sheet of board may be slit to desired widths, cut off to desired lengths and scored in one direction. D Design Style: A style of fiberboard trays or caps having flaps scored, folded and secured at flange side walls forming the depth, as opposed to a slotted style having a set of major and minor closing flaps. Die Cut: The act of cutting raw material (such as containerboard) to a desired shape (such as a box blank) by using a die. Also used to describe the resulting piece or box blank. Dimensions: 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. Outside dimensions are used in the carrier classifications and in determining pallet patterns. – Length: The larger of the two dimensions of the open face of a box as it is set up to receive product (after closing the joint). – Width: The smaller of the two dimensions of the open face. – Depth: The distance measured perpendicular to the length and width. E Edge Crush Resistance/Short Column Compression (ECT): The amount of force needed to cause compressive failure of an edge specimen of corrugated board. A primary factor in predicting the compression strength of a completed box. When using certain specifications in the carrier classifications, minimum edge crush values must be certified. End-loading/Opening Regular Slotted Container (RSC): An RSC designed to be filled from the side by sliding the product into the box. The flute direction is normally vertical when the box is in its end-opening position. F Facings: Sheets of linerboard used as the flat outer members of combined corrugated board. Sometimes called inside and outside liners. Fiber: Thread-like units of vegetable growth obtained from fibrous plants (cotton, jute) or trees (pulp wood). In the paper-making process, the individual, basic, thread-like units developed by the pulping, screening and refining of wood or recycled paper, to make new paper. Fiberboard: A general term describing combined paperboard (corrugated or solid fiber) used to manufacture containers. (See also: Combined Board)
