Some Tests Applied to Corrugated Cardboard

  • Thickness Test

It is the measurement of the distance between the bottom and top layers of corrugated cardboard. Controlling the thickness value of the treated plate is an important factor in checking whether the process is applied correctly. 

  • Box Crush Strength Test (BCT)

It is a test used to determine the amount of load that the lowest box can carry when the materials packed with corrugated cardboard are stacked with a special production BCT device made in accordance with FEFCO standards.  

  • Bursting Strength Test (BST)

It is a test to estimate the resistance of the corrugated cardboard against internal or external impacts.

  • Edge Crush Strength Test (ECT)

ECT test; It is the force required to crush the grooves as a result of applying pressure parallel to the grooves of the corrugated cardboard.

  • Horizontal Crush Strength Test (FCT)

FCT test; It is the amount of pressure required to crush the corrugated cardboard as a result of applying pressure perpendicular to the surface of the corrugated cardboard. With this test, the elasticity of the corrugated layer, in other words, the impact absorption strength is measured. 

  • Adhesion Strength Test (PAT)

It is a test to measure the degree of linear and fluting adhesion.
