Corrugated Box Equipment

Bale: A shaped unit of materials, enclosed in a fiberboard container or other wrapping, bound by strapping, rope or wire.

Basis Weight: An attribute of containerboard, but the values may be determined from the combined corrugated board. When determining the basis weight from the combined board, the take-up factor of the corrugated medium, which varies with flute size, and the weight of the adhesive must be considered.

Bending: The ability of containerboard or combined board to be folded along scorelines without rupture of the surface fibers to the point of seriously weakening the structure.

Blank or Box Blank: A flat sheet of corrugated board that has been cut, scored, and slotted, but not yet glued together.

Box Manufacturer: An establishment that has the equipment to score, slot, print and join corrugated or solid fiberboard sheets into boxes, and that regularly uses that equipment in the production of fiberboard boxes in commercial quantities.

Box Manufacturer's Certificate (BMC): A statement printed in a round or rectangular design on a corrugated box flap that certifies the box conforms to all applicable standards, and identifies its manufacturer. Sometimes referred to as a class stamp or cert stamp.

Box Style: Distinctive configuration of a box design, without regard to size. A name or number identifies styles in common use.

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.

Bulk: Unpackaged goods within a shipping container. Also, a large box used to contain a volume of product (e.g., “bulk box”).

Bundle: A shipping unit of two or more articles or boxes wrapped or fastened together by suitable means.

Caliper: Usually expressed in thousandths of an inch (mils) or sometimes referred to as "points." Caliper measurements are also used as an indirect measure of manufacturing quality.

Cardboard: A thin, stiff pasteboard used in the creation of playing cards, signs, etc. Term is often misused to refer to Boxboard (folding cartons) and Containerboard (corrugated boxes).

Carton: A folding box made from boxboard, used for consumer quantities of product. A carton is not recognized as a shipping container.

Case: As used by the packaging industry, a corrugated or solid fiberboard box.

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

Combined Board: A fabricated sheet assembled from several components, such as corrugated or solid fiberboard.

Compression Strength: A corrugated box's resistance to uniformly applied external forces. Top-to-bottom compression strength is related to the load a container may encounter when stacked. End-to-end or side-to-side compression may also be of interest for particular applications.

Containerboard: The paperboard components (linerboard, corrugating material, and chipboard) used to manufacture corrugated and solid fiberboard. The raw materials used to make containerboard may be virgin cellulose fiber, recycled fiber, or a combination of both.

Corrugated Board, Corrugated Fiberboard: The structure formed by gluing one or more sheets of fluted corrugating medium to one or more flat facings of linerboard. There are four common types:

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

  • Single Wall: Two flat facings of linerboard, one glued to each side of a corrugated medium. Also known as Double Face.

  • Double Wall: Three flat facings of linerboard, one glued to each side of two corrugated mediums.

  • Triple Wall: Four flat facings of linerboard, one glued to each side of three corrugated mediums.

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.

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 a combined board) to the desired shape (such as a box blank) by using a die.

Dimensions: The three measurements of a box: 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.

Double Wall: A corrugated board construction where two layers of the medium are glued between three layers of flat linerboard facing.

Edge Crush Resistance/Short Column Compression (ECT): The amount of force needed to crush on-edge combined board is a primary factor in predicting the compression strength of the completed box. When using certain specifications in the carrier classifications, minimum edge crush values must be certified.

Facings: Sheets of linerboard used as the flat outer members of combined corrugated board. Sometimes called inside and outside liners.

Fiberboard: A general term describing combined paperboard (corrugated or solid) used to manufacture containers.

Flaps: Extension of the sidewall panels that, when sealed, close the remaining openings of a box. Usually defined by one scoreline and three edges.

Flexo Folder Gluer: A machine, usually capable of running at high speed that prints, folds, cuts, and glues sheets of corrugated board, converting them into shipping boxes.

Flute: The wavy layer of the corrugated medium that is glued between the flat inner and outer sheets of linerboard to create the corrugated board. Fluting generally runs parallel to the height of a shipping box.

Joint: The opposite edges of the blank glued, stapled, wire stitched, or taped together to form a box.

Kraft: German word meaning “strength”; designating pulp, paper, or paperboard produced from wood fibers.

Liner: A creased fiberboard sheet inserted as a sleeve in a container and covering all sidewalls. Used to provide extra stacking strength or cushioning.

Linerboard: The flat sheets of paper that comprise the outer surfaces of a sheet of corrugated board.

Medium: The paperboard used to make the fluted layer of corrugated board.

Mullen (or Burst) Test: The Mullen Test is a standard industry measure of the bursting strength of the corrugated board.

Overlap: A design feature wherein the top and/or bottom flaps of a box do not butt, but extend one over the other. The amount of overlap is measured from flap edge to flap edge.

Pad: 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.

Palletizing: Securing and loading containers on pallets for shipment as a single unit load, typically for handling by mechanical equipment.

Panel: A "face" or "side" of a box.

Paperboard: One of the two major product categories of the paper industry. Includes the broad classification of materials made of cellulose fibers, primarily wood pulp, and recycled paper stock, on board machines. The major types are containerboard and boxboard. (The other major product group of the paper industry is paper, including printing and writing papers, packaging papers, newsprint, and tissue.)

Partition: A set of corrugated, solid fiberboard or chipboard pieces that interlock when assembled to form a number of cells into which articles may be placed for shipment.

Ply: Any of the several layers of linerboard or solid fiberboard.

Point: Term used to describe the thickness or caliper of paperboard, where one point equals one-thousandth of an inch.

Puncture Resistance: The puncture resistance of the combined board indicates the ability of the finished container to withstand external and internal point pressure forces and to protect the product during rough handling. This method is used on heavy double walls and triple walls as an alternative to burst.

Regular Slotted Container (RSC): A box style created from a single sheet of corrugated board. The sheet is scored and slotted to permit folding. Flaps extending from the side and end panels form the top and bottom of the box. The two outer flaps are one-half the container’s width in order to meet at the center of the box when folded. Flute direction may be perpendicular to the length of the sheet (usually for top-opening RSCs) or parallel to the length of the sheet (usually for end-opening RSCs).

Score or Scoreline: An impression or crease in corrugated or solid fiberboard, made to position and facilitate folds.

Scored and Slotted Sheet: A sheet of corrugated fiberboard with one or more scorelines, slots, or slits. May be further defined as a box blank, a box part, a tray or wrap, a partition piece, or an inner packing piece.

Seam: The junction created by any free edge of a container flap or panel where it abuts or rests on another portion of the container and to which it may be fastened by tape, stitches, or adhesive in the process of closing the container.

Set-up Boxes: Boxes that have been squared, with one set of end flaps sealed, ready to be filled with product. An article that is packed for shipment in a fully assembled or erected form.

Sheet: A rectangle of the combined board, untrimmed or trimmed, and sometimes scored across the corrugations when that operation is done on the corrugator. Also, a rectangle of any of the component layers of containerboard, or of paper, or a web of paperboard as it is being unwound from the roll.

Slit: A cut made in a fiberboard sheet without removal of material.

Slit Score: Shallow knife cuts made in a box blank to allow its flaps and sides to be folded into a shipping box.

Slip Sheet: A flat sheet of material used as a base upon which goods and materials may be assembled, stored, and transported.

Slot: 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 caused by the thickness of the material. Common widths are 1/4 in. (6 mm) and 3/8 in. (9 mm).

Stacking Strength: The maximum compressive load a container can bear over a given length of time, under given environmental/distribution conditions, without failing.

Tensile Strength: Indicates the containerboard's resistance to breaking when it is pulled into or through equipment during the converting and printing processes.

Tube: A sheet of combined boards, 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 provides protection and compression strength.

Unit: A large group of bundled or unbundled boxes, banded and/or stretch filmed together for shipment.

Unitized Load: A load of a number of articles or containers, bound together by means of tension strapping, plastic shrink or stretch films.

Web: A continuous sheet of paperboard or paper.

Wrap-around Blank: A scored and slotted sheet of corrugated fiberboard that is formed into a box by folding it around its contents. The user makes both the flap and joint closures.

Corrugated Boxes are Cost-Effective

The bottom line is important to all businesses. No one wants to waste money – especially on practical necessities.  

Corrugated boxes are relatively low cost to manufacture. Most of the time, custom boxes cost less than you might expect. 

Also, because they’re lightweight and can be easily stored, you can save money on storage and transportation costs.

Options for Custom Corrugated Boxes and Endless 

Corrugated box options are almost limitless. 

You can choose from all types of boards, weights, adhesives, coatings, treatments, flame resistance, static control – the list goes on. 

These packaging boxes can also be folded into all kinds of different shapes and box sizes. And we haven’t even touched on the exhaustive graphic design options corrugated boxes afford. 

There are all kinds of printing options so you can make your corrugated boxes unique to your brand.  

Corrugated Packaging Boxes are Environmentally-Friendly

Corrugated cardboard material looks like it fits the bill for consumers’ thirst to do right by the environment. Accenture recently surveyed 6,000 consumers in 11 countries and found the following:

  • 83% of respondents thought it was important or extremely important for companies to design products that could be reused or recycled.

  • 77% thought plastic was the least environmentally friendly type of packaging.

  • But the good news for corrugated boxes, 55% thought paper products were the best option for the environment. 

Let’s look at some of the reasons, corrugated boxes get high marks for protecting the environment:

Corrugated boxes are easy to recycle

You have no excuses. In most places, you can just break down your boxes and put them in your curbside pick-up.  

  • According to the EPA, in 2018, around 32.1 million tons of corrugated boxes were recycled out of 33.9 million tons of total paper and paperboard recycling.

  • That year the recycling rate for corrugated boxes was 96.5 percent. 

Corrugated cardboard boxes are renewable

Corrugated packaging is made from a high percentage of recycled material (mostly in the 70-100% range). It can be manufactured from paper pulp that comes from fast-growing pine trees, or made from wood chips and other leftover materials.

Most corrugated box manufacturers get their paper from sustainable forests. No reputable paper company is going to be clear-cutting old-growth forests.  

Nope, quite the opposite.  

After all, it’s in the interest of paper companies to keep their supply going, so they’ll take actions like replacing harvested trees with seedlings. 

Corrugated shipping boxes are reusable

Corrugated boxes are easily collapsible, so you can break them down and store them in the garage until you need one for your next move or another future use.  

Corrugated packaging boxes save energy

Since corrugated boxes are mostly made using recycled materials, it takes less energy to produce them.  

Most are made without dyes and bleaches, so that’s one less step in the production cycle. They’re also relatively light so you can save on transportation costs.

Corrugated boxes are efficient  

A corrugated box offers a lot of protection so you don’t need it to be giant-sized or filled with excessive padding inside. 

Additionally, corrugated cardboard boxes are easy to stack or collapse when not in use – so you don’t need as much space to store them.
