Corrugated board - the stuff that packaging is made of
Have you ever dreamt of waves? Our packaging experts at Model often do. Not of rushing masses of water in a warm holiday destination - but of flowing paper that joins together in several layers to form incredibly stable corrugated board.
To help you get to know the raw material corrugated board better, we have collected our concentrated expert knowledge for you. Here you can read:
- Flute types and their advantages
- flute combinations
- the technical values of corrugated board
- the secrets of different types of corrugated board
You probably use the fascinating material corrugated board almost every day. With your new corrugated board knowledge, you are guaranteed to make good packaging decisions in the future - for example, when choosing your moving or shipping boxes.
Corrugated board know-how
The advantages of corrugated board
Paper, air, glue. These ingredients provide the stable lightweight construction of corrugated board. Several layers of corrugated paper are glued to one or between several layers of another paper or cardboard.
Why is corrugated board so stable? It's because of the shape and arrangement of the corrugation. It cushions against loads from outside and inside, as the pressure is evenly distributed over the surface of the entire corrugated cardboard. This stable construction also exists in nature, for example in wasps' nests.
The corrugated board in detail
The technical values of corrugated board
What must a box made of corrugated board be able to do? It must be stable with a low dead weight, it should be inexpensive, stackable and easy to use. DIN 55468 defines three specific quality characteristics for the packaging material corrugated board:
- the bursting strength in kPa (kilopascal)
- the impact energy in joules
- the edge crush resistance in kN/m (kilonewton metres)
Corrugated board: The secret of the right grade
How do you find the right corrugated board for your application? When making your choice, always consider the size and weight of your packaged goods as well as their shipping route. This results in
- a specific flute combination (two or three flute types can be combined to give the corrugated board specific properties),
- a certain grammage and the type of base paper (for example, the particularly robust Kraftliner paper grade or the cheaper Testliner paper grade as liner paper as well as semi-chemical pulp for the flute),
- a specific packaging construction for the stability of the packaging and the protection of your product.
The FEFCO Code for a better overview
The FEFCO code makes it easier for you to keep track of the constructions of standardised shipping packaging. This is because all standard boxes made of corrugated cardboard have an internationally used code that simplifies communication between manufacturer, retailer and consumer.
