In terms of cardboard boxes, corrugated cardboard plays a particularly important role. Corrugated cardboard determines many factors such as product quality, product aesthetics, product durability, and more. However, not everyone fully understands corrugated cardboard. So, what is corrugated cardboard? What types of corrugation are commonly used in cardboard box manufacturing today? Let's explore this together with Hoang Phuc Pack in this article!

1. What is corrugated cardboard? Why do cardboard boxes have corrugated layers?

Corrugated cardboard is produced using rolls of paper as raw material. Then, through a production line and corrugating machines, it is formed into finished sheets of paper with a corrugated pattern and evenly spaced folds.

Corrugated cardboard is extremely important in the production of cardboard boxes. Thanks to corrugated cardboard, the quality of cardboard boxes is significantly enhanced. The interlocking corrugated layers provide cardboard boxes with strength and load-bearing capacity. The more corrugated layers there are, the better the load-bearing capacity of the cardboard box, helping it withstand high puncture forces and reducing the likelihood of tearing or damage. This makes businesses, customers, and freight carriers feel satisfied and reassured.

2. Some popular types of corrugated cardboard today

Corrugated cardboard today comes in a wide variety of styles and sizes, depending on the user's needs and intended purpose. The seven types of corrugated cardboard commonly used today are A-flute, B-flute, C-flute, E-flute, AB-flute, BC-flute, and BCE-flute. Among them, the most commonly used types in cardboard box manufacturing are B-flute, C-flute, E-flute, and BC-flute. Each type of corrugation has different characteristics:

B-flute: The paper flute height is 2.2–3.0 mm. Cardboard using B-flute can withstand high puncture forces, so it is often used to transport heavy products or ship items over long distances.
C-flute: The paper flute height is 3.2–4.0 mm. C-flute combines the advantages of A and B flutes. That is, it can both distribute force well across its surface and withstand high puncture forces. This is the most widely used flute for manufacturing cardboard boxes, folding cartons, and containers for fruits and vegetables.
E-flute: The paper flute height is 1.0–1.8 mm. This is the thinnest flute among all the other types and is commonly used for boxes containing lightweight items.
BC-flute: This is a double flute combining B and C flutes. The paper flute height of 5.4–7.0 mm provides box thickness and high load-bearing capacity.

Each type of flute has its own advantages, so you should research them carefully before purchasing them for packaging goods. For heavy items, pay attention to flutes that can distribute and withstand force well. Conversely, for thin and lightweight products, choose a moderately thin flute to both save costs and ensure that the goods are safely protected.

3. How many corrugated layers does a 7-layer cardboard box have?

The 7-layer cardboard box is considered to have high protection capabilities, and its large weight and size allow it to hold a wide variety of goods. A 7-layer cardboard box consists of the following components:

Two outer cardboard layers: These display company information such as the brand, product name, address, and more, so they should be printed very carefully. The box surface must ensure aesthetic appeal, remain free of scratches, and be made from high-quality paper.
Three middle corrugated layers: Different types of flutes are available depending on the user's needs. Manufacturers commonly use B-flute or BC-flute to ensure product durability.
Two cardboard layers between the corrugated layers: These are the remaining two sides of the corrugated layer, which are bonded to the top layer and the bottom layer of the cardboard box.

Each type of flute has its own structure and distinct advantages. Therefore, before purchasing, you should thoroughly research the structure and function of each type.
