2 Most Vital Paper Tests For Strength Properties

It is difficult to comprehend the mechanical properties of paper in basic terms. Many global laboratories have been researching and studying it. Through this research, they aim at understanding the relationship between the properties and structure of the paper and papermaking processes. This further aims at becoming able to create custom-made paper properties that meet the ultimate requirements. While this study is still under process, manufacturers have found an alternative way to test and know the complex properties of a paper. These ways are nothing but physical property testing methods (or TAPPI methods) via testing machines, to determine the required properties of different kinds of papers. 

Bursting strength, tensile strength, tearing resistance, folding endurance, etc. are some of the many properties that the testing machines evaluate. Following we have described 2 major tests of strength properties- tensile strength and tearing resistance. Let’s quickly read about it.

2 Most Vital Paper Tests For Strength Properties

1. Tensile Strength 

The tensile strength measures the tensile breaking strength and elongation of paper as well as paperboard. Manufacturers use UEC’s tensile strength testing machine to conduct the test. The machine evaluates the tensile strength, elongation and its percentage, and the breaking length of paper, board, and tissue paper in the dry or wet form.

2. Tearing Resistance

This test is the most vital and commonly performed test in the paper industry. Also called the Elmendorf tear test, it determines the internal tearing resistance of paper. Internal tearing resistance measures the force or pressure perpendicular to the paper surface essential to tear one sheet from a particular distance. UEC’s tear resistance testing machine conducts this test on papers, boards, plastic films, and similar materials with great accuracy. 

Final Thoughts

Investing in the right paper physical property testing machines can be beneficial for the manufacturers by the time the research in laboratories comes up with some great results. Connect with UEC to invest in these machines. Also, opt for a demo before you purchase essential equipment.
