Overview
The Digital Tear Tester (Elmendorf Type) By QGI – Quantum Global Incorporation Is A Precision Laboratory Instrument Designed To Measure The Tear Resistance Of Paper, Paperboard, Tissue, And Packaging Materials.
Engineered As Per Iso 1974, Tappi T414, And Relevant International Standards, This Tester Ensures Accurate And Repeatable Results For Quality Control And Research Laboratories.
What Is Tear Strength In Paper?
Tear Strength Refers To The Force Required To Continue Tearing An Already Initiated Cut In Paper Or Board. It Is A Critical Parameter That Affects:
Packaging Durability
Resistance To Rough Handling
Print Performance
Material Toughness
Corrugated Board Strength
Proper Tear Resistance Ensures Better Performance During Converting, Printing, And Transportation.
Working Principle (Elmendorf Method)
The Digital Tear Tester Operates On The Elmendorf Pendulum Principle, Where:
A Pre-Cut Specimen Is Clamped Vertically.
A Pendulum Swings And Tears The Sample.
The Loss Of Energy During Tearing Is Measured.
The Instrument Calculates Tear Strength Digitally.
