Most people know what cardboard is, but did you know it comes in many different types and forms? You may have seen the term corrugated cardboard online, in one of our previous articles or when ordering boxes online. But what exactly is corrugated cardboard, and why is it Jetbox’s cardboard of choice?
How is Corrugated Cardboard Made?
The journey for corrugated cardboard begins in the paper mill. Rolls of paper are made and then sent to a corrugating, or converting, plant. This paper is then crimped, layered and glued together to form corrugated cardboard. Once the cardboard has been made, it is cut, printed and folded to suit the needs of the business purchasing it. Corrugated cardboard is used for things such as displays, shipping boxes and moving boxes.
What does the inside of Corrugated Cardboard Look Like?
Corrugated cardboard is made up of three different layers, like a cardboard sandwich. The two outer layers are referred to as the inside liner and outside liner, with the middle layer a ruffled cardboard known as the fluting medium. The benefits of a cardboard made with layers like this are many, and include:
- Product Protection
- High strength to weight ratio
- Budget friendly
- Environmentally friendly
What Are the Different Types of Corrugated Cardboard?
When it comes to customising corrugated cardboard for your needs, there are a number of ways we can do this! From different wall types, to appearance and flute types, corrugated cardboard is made to suit you. No matter how you customise it, the benefits of corrugated cardboard remain the same, so no need to worry!
Different Wall Types for Corrugated Cardboard
As described above, the most common way to make corrugated cardboard is with a single piece of fluted material between two pieces of liner. This is known as a single wall. However, corrugated cardboard also comes in double and triple wall board.
Double wall, also known as twin cushion, has two pieces of fluted material, with three pieces of liner. The order is the same, liner – flute – liner with an additional flute and liner on top. This type of board is resistant to breaking when stacked and is commonly used in industrial settings. At Jetbox, we offer a number of different twin cushion cardboard options, as well as single and triple. Check out our website to see our range of approximately 80 cardboard grades!
Triple wall is three pieces of fluted material between four pieces of liner. Triple wall corrugated cardboard is so sturdy that it acts as a substitute for wooden shipping crates.
Appearance Options for Corrugated Cardboard
The look of your cardboard is dependent on the materials you choose to use. Recycled paper has a different look to kraft paper, for example, where the board is made using different products. Kraft board itself can come in brown or white. If you are looking for a certain colour, be sure to get in contact with your cardboard box supplier!
Different Flute Types for Corrugated Cardboard
For those just beginning their corrugated journey, it can be easy to assume that the thicker the cardboard, the stronger the box. This is, however, a common misconception. The type of flute plays a major role in the strength and purpose of a box, and you cannot always tell how well a box will hold up on its thickness alone. It is also important to note that the cardboard alone shouldn’t be your only form of protection, with things such as inserts and sleeves an important part of your packaging.
