Determining the Crushing Strength of Kraft Liner & Fluting

Crush tests, where the Kraft paper samples are crushed to determine their resistance to crushing pressure, are among the most mandatory tests in the paper testing industry. These tests are performed by experts as per the international industry standards. Ring crush test and edge crush test are among the most common and vital crush tests for Kraft paper/liner. For each test, there is specialized equipment. Let us learn about both of them in the section below. 


2 Most Crucial Crushing Tests for Kraft Liner & Fluting


Edge Crush Test

The edge crush test is performed to determine if the edges of the Kraft material are strong. It is completed using a laboratory edge crush tester. The tester tells manufacturers how well the Kraft paper can withstand damage and crushing possibilities during both storage and transit. 


UEC’s Laboratory crush tester accurately measures this parameter for paper, board, corrugated board, and solid fiberboard. The equipment comes with a digital display that displays the test results once the evaluation is done. Manufacturers get a sample holder, sample cutter, and removable disc along with the main unit to conduct the test accurately.

 

Ring Crush Test

The ring crush test evaluates the crush strength of the ring-shaped paper sample. This test is similar to the short-span compression test. In both the tests, the strength of the Kraft liner or fluting is measured in both, the machine and perpendicular direction.  


To perform this test precisely, manufacturers make use of UEC’s ring crush tester. This reliable equipment comes with a touchscreen HMI panel. It displays the test results, both graphically and in numbers, using a single-touch function. During the test, the force applied should be precisely perpendicular to the sample. While specimen preparation is also crucial to achieving the test results.


In addition to the main unit, the manufacturers also get a test sample holder and a removable disc. Besides, they may also opt for an inbuilt thermal printer for printing objectives and data transfer software. 


Summary

Both ring crust test and edge crush tests are crucial to determine the crushing strength of Kraft liner. And to perform these tests, it is important that manufacturers invest in reliable crush testers. UEC excels as a competent manufacturer and supplier of paper physical property testers. Manufacturers must get in touch with the company’s experts and make possible an informed buying decision. Visit the website to know more.
