Corrugated cardboards are produced in machines that require high precision. These are machines
that produce at a speed of 500 feet (157 m/min) per minute and have very complex mechanisms to
prevent some problems such as warping and deformation.
Papers are moistened with high steam pressure. The purpose of moistening is to give the paper
waves the desired properties and to soften them for pasting. The process requires a significant
amount of water.
Paper plates are dehumidified after shaping. In their new form, they are dried at 248-356 F degrees
(120-180 C). Very high energy is consumed in the production of corrugated cardboard.
This parcel raw material, obtained from cellulose and copper fibres, takes its strength from the
copper combination it contains. While the paper called linear is used on the front side of this parcel
type, fluting type paper is used on the inside.
Common types of corrugation are "A", "B", "C", "E", and "F" waves. The letter designation is based on
the order in which they were invented, not relative sizes. Groove size refers to the number of
corrugations per 1 meter, although it may differ for different corrugated manufacturers. An
important criterion here is the factor defined as the corrugation coefficient, which, in practical terms,
expresses how long the ironed state of the corrugated paper extends compared to the first case
