Corrugated cardboard has a wavy layer in the middle. This makes it much stronger than plain cardboard. If you need to ship heavy things, use corrugated cardboard. For light things, regular cardboard is fine.
Here is a quick comparison:
| Feature | Cardboard | Corrugated Cardboard |
|---|---|---|
| Structure | Single layer | Wavy layer + flat sheets |
| Strength | Low | High |
| Best Use | Light packaging | Shipping, heavy items |
Corrugated fiberboard is the full name for this material. Most shipping boxes use it. It is made by joining the wavy layer and flat sheets. This makes a strong and sturdy board. Corrugated fiberboard comes in different thicknesses. Some have one wavy layer. Others have two or three. You can pick the type you need. This material is easy to cut and fold. You can also print on it. You see corrugated fiberboard in many stores and warehouses.
When you look at corrugated cardboard, you see two main parts. The flat sheets on the outside are called linerboard. These sheets give the board a smooth surface. They also add strength. The wavy layer in the middle is the medium. This layer forms the flutes. The medium helps the corrugated board absorb shocks. You find both linerboard and medium in every piece of corrugated cardboard.
Tip: Linerboard often uses strong kraft paper. This makes your boxes tougher and more reliable.
Flutes are the wavy shapes inside corrugated cardboard. They make the board stiff and strong. You can find different flute types. Each type has a special letter name, like A, B, C, E, or F. The size and shape of the flute change how the board works.
| Flute Type | Height (mm) | Uses |
|---|---|---|
| A | 4.5–5.0 | Heavy-duty packaging |
| B | 2.5–3.0 | Food boxes, retail displays |
| C | 3.5–4.0 | Shipping boxes |
| E | 1.0–1.5 | Small boxes, printing |
| F | 0.8 | Retail packaging |
You can pick the right flute type for your needs. Some flutes protect better. Others save space.
Corrugated cardboard comes in different constructions. The most basic is single face. This has one linerboard and one medium. Single wall uses two linerboards with one medium in between. Double wall adds another medium and linerboard. Triple wall uses three mediums and four linerboards. These layers create a combined board. You can use combined board for heavy or fragile items.
Single Face: Light protection, flexible
Single Wall: Most common, good for shipping
Double Wall: Extra strength, heavy items
Triple Wall: Maximum strength, industrial use
Note: Combined board gives you more choices for strength and protection. You can match the board to your product.
You might wonder what cardboard is made from. The answer is paper. Most factories use kraft paper as the main part. Kraft paper comes from wood pulp. Some companies use recycled paper too. This mix makes packaging strong and eco-friendly. Both linerboard and medium use these materials. This gives every box a sturdy base.
Tip: Using recycled content helps nature and saves resources.
The corrugating process changes flat sheets into strong packaging. First, machines heat and wet the medium. This makes the paper soft and easy to shape. Next, rollers press the medium into waves. These waves are called flutes. The machine glues the fluted medium between two flat linerboards. This is when you see the corrugated look appear. The glue dries fast and holds the layers together.
You can watch the board move through the machine in one long piece. The process keeps the paper moving quickly. The finished board comes out strong and ready to cut.
You may ask how cardboard is made. The answer has several steps. After corrugating, the board goes to the cutting area. Machines cut the big sheets into smaller pieces. Workers or machines score the sheets for folding into boxes. Some factories print designs or labels on the surface. The last step shapes the board into boxes or other items.
You get corrugated cardboard for many uses. The process makes sure each box is strong and dependable. You can trust these boxes for shipping and storage.
Factories use special machines to make corrugated paper. The main machine is called the corrugator. This machine heats, shapes, glues, and presses the paper. The corrugator makes the flutes and joins the layers. Other machines cut, print, and fold the finished board. Some machines add coatings or extra layers for special needs.
You see technology working at every step. Modern machines help make high-quality corrugated cardboard fast. These machines also let you use recycled paper and save energy.
Note: The right machines make production safe, quick, and efficient.
Corrugated fiberboard comes in several types. Each type gives you different levels of strength and protection. You can choose the right one for your needs by learning about each type.

Many businesses pick double wall for stacking boxes or shipping fragile goods. It resists crushing better than single wall.
| Type | Layers of Liner | Layers of Flute | Best Use |
|---|---|---|---|
| Single Face | 1 | 1 | Wrapping, padding |
| Single Wall | 2 | 1 | Shipping, storage |
| Double Wall | 3 | 2 | Heavy or fragile items |
| Triple Wall | 4 | 3 | Industrial, bulk loads |
Triple wall combined board is the strongest type of corrugated fiberboard. It has four flat liners and three wavy layers. You can use triple wall for very heavy or bulky items. Many factories use triple wall for shipping machines or large parts. This type acts almost like wood in strength. You get the best protection for your products with triple wall cardboard.
