Testing the quality and resistance of corrugated board

Corrugated board: a technical marvel!

Corrugated board is a technical marvel. It looks like little, but develops amazing powers and is a true all-rounder. In global trade, it is the number one packaging material. The quality must be right, then there are hardly any restrictions on the use of corrugated board to protect products.
Moisture, pressure, mold, and impacts are external influences that can affect corrugated board. Your products will suffer from this. Especially if these products undertake a long sea voyage in a container. We will test for you whether the corrugated board you have selected can withstand all these resistances:

  • Strength tests on corrugated board to determine quality
  • Collapse tests and edge crush resistance (ECT)
  • Determination of load bearing capacity
  • Influence of climatic loads on strength

You are a manufacturer of corrugated board? Great!

Companies that produce or want to use packaging for overseas transport can have any corrugated board quality tested by us. As an accredited testing institute, we test all the properties of the various corrugated board grades.

Depending on the shipping method, the corrugated board must have special functions. Knowing these is particularly important not only for packaging developers. Professional packers also need to have the right grade to hand, because the difference between packaging small parts and protecting industrial goods with corrugated board is enormous.

The corrugated board has to have special properties depending on the shipping method.

Compare EUPS Corrugated Quality

Based on our research work and many years of practical experience, we have developed a solution: Our End Use Performance Standard (EUPS) for corrugated board. This can serve as a basis for decision-making. With the help of this standard and test structures, we can test corrugated board and thus express its bursting strength, crush resistance or flexural strength in values. These can then be compared and allow to optimize the cost-performance ratio in the selection of corrugated board.
