Box crush test. It provides the determination of the vertical maximum force that can be applied to the boxes.


Corrugated cardboard surface; It is the process of coating with various substances to increase its resistance against water, moisture, and oil permeability. While wax (wax) material was used in the past, today water-based products are used that do not adversely affect the reuse of paper. The application place is the corrugated machine.

COBB Value

It is a measure of the water-resistance of the cardboard surface or its acceptance of water. In other words, it is the degree of gluing of the cardboard and examines the printability and machinability properties of the cardboard.


The edge crush test provides the determination of the strength of the boxes perpendicular to the grooves for stacking resistance.

Groove Direction

It is perpendicular to the working direction in the corrugated machine and parallel to the working direction in the box production machines.


To facilitate the transportation of corrugated cardboard boxes, they are usually full or half-cut holes with special molds, large enough to enter the hand (30 x 90mm), located on the narrow sides of the boxes. 


Fluting paper, paraffin, etc., to give corrugated cardboard durability, moisture resistance, high stacking strength. material impregnation. It is applied in the corrugated machine.

Insertion Ear

It is a narrow strip with a width of 25-40 mm and a height of the box, joining the narrow and wide face, to make the corrugated cardboard sheet into a prism.


It is determined by drying the cardboard at 105°C. Cardboard moisture affects the printability, machinability, and even usability of the cardboard.


It is the cutting of the corrugated cardboard sheet only at certain points on the same line so that it can be easily folded in both directions (inside-outside) from the desired location. It is used in molded production.


The corrugated cardboard sheets cut in the desired dimensions in the corrugated machine are called a sheet, which is a very old term in the sector.


The annular crush test is for determining the strength of papers perpendicular to the fiber direction.


It is the traces made by the corrugated machine, slotters, or mold knives so that the corrugated cardboard sheet can be folded. This word, which is called pilyaj in printing, is expressed as trace or ril by corrugated cardboard manufacturers. 


It is the name given to the cardboard, corrugated cardboard, styrofoam, or air cushion placed between the packaging and the product. The hard and sharp points of the products to be packaged may be penetrating to the parts that touch the package, or the product may need more protection against impacts and falls. In such and similar cases, a separator is placed between the product and the package.


They are the slits opened after the slotter rills to form the box lids.

Slotted Rile

They are rollers that are thrown on the corrugated board in the corrugated machine so that the box covers can be folded. They always come perpendicular to the grooves.

Vent Hole

Corrugated cardboard boxes are usually circular holes cut with special molds to allow the products to be ventilated.


The corrugation, seen in the section perpendicular to the grooves, is defined by the name of the wave because of its shape.


It is the distance between the sticking points of the corrugated cardboard in single-sided or corrugated cardboard.

Wave Height

It is the height between the upper and lower arches formed by corrugated fluting paper.


The basic feature, the weight, is the weight of 1m2 of the cardboard. The weight area is one of the defining features of a cardboard machine. Some other important properties of cardboard vary depending on the weight. Weight has no function in printing, box making, filling, and use.
