Folding Carton: is a term used to refer to a box that is made from paperboard which could be printed or plain that is cut, creased & glued into a variety of styles & sizes.



Basis Weight: 

Bending Chip Board: is the cheapest grade of paperboard used in folding carton manufacturing, it is mainly made up of recycled fibres. 

Blank: is a folding carton after it has been die-cut (cut & creased) but but before it has been folded & glued.

Boxboard: is a term used to identify the different types of paper materials used in manufacturing of folding cartons. Also known as "Paperboard".


Caliper: is a measurement of the thickness of the paperboard, it is expressed in thousands of a inch.

Carton: is a container which can be made with various types of paperboard. It is often used a short form for "Folding Carton". Cartons do not include the following type of boxes: rigid/setup boxes, corrugated, or shipping containers.


Carrier Board: is a Kraft board that is mainly used for beverage carriers due to its ability to resist moisture, allowing for board to be exposed to water or liquids while maintaining its strength.

Chipboard: is a low quality board that is made from paper waste. This type of board is used when strength & quality is not important.

Clay Coated Board: is a high grade quality board that has a top side that is "Clay Coated" which creates a perfect surface for high quality printing.

Coating: is a liquid substance that is added onto the box board during the printing process or after the print it complete. It is used to enhance the print & also provide a protective layer over the printed image. Can include varnish, aqueous (AQ), or ultra-violet (UV) coatings.

CAD (Computer Aided Design): is computer program used to design folding cartons. It provides information needed for layouts & the manufacture of dies used for die cutting (cutting & creasing process).

Computer to Plate (CTP): is a digital process of designing & transferring print direct to machine that outputs printing plates, without the need of film.

Creasing: is done in the die cutting stage, it is the creation of the score or folding line that allows the box to take its shape. It is done by pressing the printed or non-printed sheet (board) onto a steel rule die on a die-cutting press.

Cut: is to completely shear or pierce through a sheet or board, cutting a blank completely from a sheet of board.

Cut Score: is partially piercing through a sheet or board. 

Cut & Crease: is a type of fold line that is made up of series of alternating cuts & creases. Aka as a perforation (perf), allowing for an easier more square fold.


Debossing: is technically negative embossing. It is done by depressing an image or shape into the paperboard.

Die: is used for shaping, cutting, stamping out blanks. It is usually made from wood as the base & the cutting and creasing rules made from steel. There are also rubber pieces places around creasing rules for technical reasons.

Die Cutting: is the process of cutting & creasing a flat sheet of board using a die.


Display: is a point of purchase display that is a folding carton style, it is used for holding numerous individual packages or products.


Dust Flaps: are the unglued flaps that extend & fold down into the carton when closing to keep dust & other particles out.



Embossing: is the opposite of debossing, whereby letters or images are raised up above the rest of the carton. This process is done in the die cutting stage & gives areas on the box a 3D feel & look.




Film: is a flexible plastic material, usually clear, that is used as a window on a carton.

Foil Stamping: is the impressing of lettering or a design through foil onto a carton through a heated die, also done in the die cutting process.
