Determination of edge compression strength of corrugated base paper

The edge crushing strength of corrugated base paper refers to the ability of corrugated cardboard to withstand lateral pressure, also known as edge crushing strength or shear strength. This index is usually used to evaluate the strength and durability of corrugated board.

The edge crush strength of corrugated base paper can be measured by the following steps:

1. Prepare testing equipment: corrugated base paper edge crush Tester, sample cutter, sample mold.

2. Cut the corrugated base paper into samples of specified size using a sample cutter and a sample die. Usually, the width of the sample is parallel to the corrugation direction, and the length is perpendicular to the corrugation direction.

3. Put the sample into the corrugated base paper edge crush strength testing machine, and set it according to the equipment manual.

4. Before starting the test, adjust the test head and pressure to suit the size and material of the sample according to the equipment manual.

5. Place the sample on the test platform and adjust the position and direction of the sample.

6. To start the test, lateral pressure is applied at a specified rate until the sample deforms or breaks.

7. Record the pressure and displacement data during the test, process the data, and calculate the edge compression strength of the sample.

NBCHAO reminds you: when testing the edge crush strength of corrugated base paper, the consistency of the test environment should be maintained to avoid the influence of interference factors on the test results. In addition, care should be taken when testing to avoid injury from the test head or sample cutter. Before testing, appropriate test conditions and test methods should also be selected, and international standards should be followed.
