What is Corrugated Board
Corrugated board is a multi-layer sheet material in which one or more layers of fluting paper are formed into a wave structure (flute) and glued to flat liner layers. It is precisely the flute that provides rigidity, cushioning and thermal insulation.
In Belarus and the CIS, production is governed by GOST 7376-89 "Corrugated board. General technical specifications". The standard defines the types (D, T, P), grades (T21–T27, P31–P37), flute profiles (A, B, C, E) and the norms for physical and mechanical properties.
Type D — 2-layer
Type T — 3-layer
Type P — 5-layer
2-Layer
Type D1 liner + 1 flute
Light wrapping and ancillary packaging

How Corrugated Packaging Is Made
Understanding the process helps you formulate the technical brief correctly and choose the optimal grade.
01
Choosing grade and profile
The board type (T or P), grade (T21–T24, etc.) and flute profile (A, B, C, E) are selected for the load and transport conditions. Profile C is the most universal: it balances cushioning and stacking strength.
02
Designing the construction
From a product drawing or sample, a FEFCO construction code is chosen. The blank dimensions are calculated allowing for board thickness and process tolerances.
03
Manufacturing on the line
The corrugator forms the web. The rotary slotter cuts and creases (makes fold lines). Flexo printing is applied if needed. A semi-automatic or automatic folder-gluer assembles the blank.
04
Inspection and shipment
Dimensional accuracy, gluing quality and print consistency are checked. Goods are palletised and labelled. Accompanying documents for accounting are supplied with the batch.
Corrugated Board Grades per GOST 7376-89
Characteristics from Table 2 of GOST 7376-89. ECT is the edge crush test along the flutes. This is the very indicator that determines a box's load-bearing capacity when stacked.
Type T — 3-layer
Composition: outer liner + flute + inner liner. The most common type. Grades T21–T27 in descending order of strength.
| Grade | ECT, kN/m (min) | Long. tear, kN/m | Application |
|---|---|---|---|
| T21 | 2.2 | 4 | Light items, inserts, ancillary packaging |
| T22 | 3.0 | 6 | Consumer goods, cosmetics, paper products |
| T23 | 3.8 | 7 | Food, household chemicals, universal transport packaging |
| T24 | 4.6 | 8 | Relatively heavy or fragile goods, reinforced transport packaging |
| T25 | 5.4 | 9 | Industrial parts, metalware, machinery |
| T26 | 6.2 | 10 | Heavy loads, spare parts, export packaging |
| T27 | 7.0 | 11 | Maximum strength for 3-layer: large industrial loads |
* Data from Table 2 of GOST 7376-89. The specific flute profile (A, B, C) is chosen separately and affects sheet thickness and cushioning, but not the grade.
Type P — 5-layer
Composition: 3 liners + 2 flutes. Significantly higher rigidity and stacking load-bearing capacity compared to T. Grades P31–P37.
| Grade | ECT, kN/m (min) | Long. tear, kN/m | Application |
|---|---|---|---|
| P31 | 3.8 | 7 | Medium loads with high storage stacks |
| P32 | 4.6 | 8 | Food, pharmaceutical and household industries |
| P33 | 5.4 | 9 | Oversized goods and equipment |
| P34 | 6.2 | 10 | Heavy industrial loads, export packaging |
| P35 | 7.0 | 11 | High-load export and warehouse packaging |
Type D — 2-layer
One liner + one flute. Used for wrapping and ancillary packaging, pads and cradles inside boxes. The standard defines grades D11–D16.
* Source: GOST 7376-89, Table 2. Grades P36 and P37 are provided by the standard and produced on request.
Flute Profiles (fluting type)
The profile defines the height and pitch of the fluting wave. The same board grade, for example T23, can be produced with profile B, C or BC — the choice affects cushioning, rigidity and print quality.
A
Coarse
Height: 4.4–5.5 mm · Pitch: 8–9.5 mm
Maximum cushioning. Fragile goods, glass, ceramics. Stacks well. Printing is difficult.
B
Fine
Height: 2.2–3.2 mm · Pitch: 4.5–6.4 mm
High rigidity. Canned and food goods. Excellent surface for flexo printing and die-cutting.
C
Medium
Height: 3.2–4.4 mm · Pitch: 6.5–8 mm
Universal. Balance of cushioning and stacking strength. The most common.
E
Micro
Height: 1.1–1.6 mm · Pitch: 3.2–3.6 mm
Thin board, smooth surface. Display, consumer and gift boxes.
BC
Double
B + C profile in one sheet (5-layer)
5-layer combo. High rigidity and cushioning at once. Electronics, equipment.
