Use Of Edge Crush Value In Ensuring Best Quality Of Packaging Containers

In packaging industries, the strength of the packaging materials is one of the most important concerns for the manufacturers. The manufacturers need to rest assured that they are providing the best quality and strength of the products to the customers for better safety of their products.  The Edge Crush Tester is one of the fundamental properties of the packaging materials like corrugated sheets, cardboard, etc. that gives information about the quality and strength of the packaging containers. The edge crush value of any material gives the amount of force that can be applied to the material without causing any deflection. This property is very useful in determining the sustainability of the materials during rigorous usage conditions.

For determining the edge crush value of a given material, edge crush tester is used. The specimen is placed in the test fixture, and then the test fixture is placed between the compression plates. After proper placement of the sample, the test is started. The compression plates apply a compressive force on the specimen until deflection. Once the specimen is deflected, the test stops. The maximum load applied to the specimen is recorded on the load indicator. This gives the edge crush value of the specimen.

When the edge crush value of a packaging material is determined, it not only gives the information about the quality and strength of the materials but this edge crush value can be used for calculating the box compression strength of the final packaging containers as well. The box compression value is calculated with the help of McKee’s formula which is given as
