Glossary Staples or Stitches: 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. Substrate: The surface or base material on which an adhesive-containing substance is spread for bonding, coating or other purposes or on which printing is done. T Tape: A narrow strip of cloth, paper or plastic sometimes having a filler or reinforcement, coated on one side with an adhesive, and used to seal the joint or flaps of a fiberboard box or to reinforce a box. Taper: Machine that applies tape to the joint or flaps of a fiberboard box. Tensile Strength: The maximum tension a material can resist before breaking. Test: Used alone, the word refers to the bursting strength of linerboard or combined board, where that is the applicable measure of strength (See: Test Procedures). In Europe, test liner is linerboard made from recycled materials. Top-opening Regular Slotted Container: An RSC designed to be filled from the top and remain upright. The flute direction is normally vertical, providing maximum stacking strength. Tube: 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. (See also: Shell) U U-Liner: A protective cushion or a divider in a box, usually made from singlewall corrugated board, in the shape of the letter U. United Inches: Sum of the external dimensions of a box; i.e., length, width and depth. Unitized Load: A load of a number of articles or containers, bound together by means of tension strapping, plastic shrink or stretch films. Universal Product Code (UPC): A 12- or 13-digit, numeric code that uniquely distinguishes products. V Virgin Fiber: Fiber that is derived directly from wood. W Water Resistant: Having a degree of resistance to damage or deterioration by water, after it is sized (treated with water-repellent materials). Wax Cascaded or Wax Saturated: Combined board that is treated by cascading molten paraffin wax or wax blend over vertical box blanks so that it seeps down the flutes as well as over the facings. Wax Curtain-Coated: Combined corrugated board that has been surface coated on one or both sides with a hot-melt wax blend.
