Corrugated Cardboard Carton
It is a type of cardboard consisting of multiple layers of paper.
Flat layers are called Plastering, wavy interlayers are called Corrugated.
Respectively, a plastering is obtained by gluing the layers arranged as a corrugation to each other.
The papers used in the plastering layers are called "liner" and the papers used in the corrugated layers are called "fluting".
Paper Weight
Grams is the weight of a unit area of paper.
The unit of measurement is gr/m 2 (Gram/Square Meter).
In the same type of paper, it is expected that the strength will increase as the weight increases.
Corrugation Coefficient
It is the straight length of corrugated paper needed to stick 1 meter of plastering.
It changes according to the wave type.
Straw Fluting:
Corrugated cardboard is normally used in the corrugated layer in the manufacture of cardboard.
However, it is frequently used in plastering layers due to its low cost.
It is produced at OMAS.
NSSC (Neutral Sulphite Semi-Chemical) Fluting:
It is a semi-chemical paper used in corrugated cardboard production, in the corrugated layer of packaging materials that require high strength.
Testliner:
It is used in plastering layers in corrugated cardboard production.
It is usually brown or white in color.
Omliner (Omas Imitation/OMIM):
It is the name given to the Testliner produced in OMAS as a brunette.
It is used in plastering layers in corrugated cardboard production.
Kraftliner:
Corrugated cardboard is generally used in the outer plastering layers, sometimes in the inner plastering layer, in the manufacture of cardboard.
Its quality and strength are high.
A Wave (Big Wave): Height is between 4.0-4.8 mm,
number of grooves in 1 meter is between 105-125,
Corrugation coefficient is between 1.48 and 1.53.
It is not applied in OMAS.
B Wave (Fine Wave): It is the thinnest wave produced in OMAS.
The wave height is between 2.2-3.0 mm, the
number of grooves in 1 meter is between
153-181, the coefficient of corrugation is between 1.28 - 1.43.
For corrugating rollers in OMAS, this coefficient is 1.43.
C Wave (Medium Wave): It is also called “Bold Wave” as it is the thickest wave produced in OMAS.
Wave Height is in the range of 3.2-4.0 mm,
In general, the number of grooves in 1 meter is between
125-147, the coefficient of corrugation is between 1.42 - 1.50.
But for corrugating rollers in OMAS, this coefficient is 1.53.
E Wave (Micro Wave): Wave height is between 1.0-1.8 mm,
number of grooves in 1 meter is between 285-334,
Corrugation coefficient is between 1.22 and 1.29.
BC Wave (Dopel): It is a 5-layer cardboard consisting of external spinning, B corrugation, middle spinning, Condula and inner spinning.
Since both the B wave and the C wave are used, it is also called "Dope", which means double.
In fact, the combination of any two waves also means double wave, but in common usage, Dopel and BC wave are meant.
The wall thickness is around 6 mm.
It is used to increase strength and impact resistance.
BE Wave (Mikrodopel): It is a 5-layer cardboard consisting of outer spinning, B corrugation, middle spinning, E corrugation and inner spinning.
Since both B wave and E wave are used, it is also called "Microdope" which means double and microwave is used.
The wall thickness is around 5 mm.
It is used to increase strength and impact resistance.
Other Wave Types: Apart from these, there are F Wave, K Wave and N Wave types and alternative two-wave (like AB, AC, BE) and three-wave (like BAC, EBC, BCB) cardboards for special needs, which are not used much in the market.
