When we are in the paper manufacturing business, we have to keep testing products to provide the best quality to our customers. These products must also comply with the industry requirements and standards so that they can be introduced to the market and put into applications.
In the process of ensuring different parameters of paper, paper products, and similar materials, manufacturers invest in several machines. These machines range from tensile testers, strength testers, absorbency, brightness, stiffness, weight testers, and many others. Among the long list of paper testing machines, we will throw light on one popular and two lesser-known testers that manufacturers must have in their units.

Paper stiffness tester
Paper brightness tester
So, let’s jump to the following section to understand these testers one by one.
Understanding The Use of 3 Different Types of Paper Testers
Tensile Tester
A tensile tester is used to quickly determine the tensile strength of paper, paperboard, and tissue paper. It also helps manufacturers learn about the elongation or stretch, the percentage of elongation, and the breaking length of the paper. The tensile tester is capable of testing the sample in both a wet and dry state.
It comes with the following components:
Standard load cell
Sample clamping jaws - 15 mm
Microprocessor
Touch screen.
Manufacturers can also opt for optional components like:
Specimen cutter
Sample clamping jaws
Load cells of varied capacities
Standard calibration check weights
Thermal printer
Windows-based software to transfer the data
Paper Stiffness Tester
The paper stiffness tester is used to determine the stiffness and resilience of the paper. Both the stiffness and the resilient properties can be evaluated up to ten thousand Taber stiffness units. Materials like paper, paper products, plastic, cardboard, metal sheets, and similar flexible materials can be tested in this equipment.
In addition to the existing components of a paper stiffness tester, manufacturers can opt for a triple shear cutter and calibration standard strips.
Paper Brightness Tester
The paper brightness tester is another significant instrument just like the tensile and stiffness testers. It is used to determine the brightness of the paper and similar materials. In addition, it also measures the opacity and gloss of the materials. Even ceramic and powdered materials can also be evaluated for brightness on the paper brightness tester.
The unit is easy to operate and once the test is completed, the test values are displayed on the digital panel.
The paper brightness tester is operated with the following components:
Filters
Photocell and tungsten lamp for light
Gloss search unit (optional)
Powder press (optional)
Digital Panel
Wrapping Up
So, these are the three different types of testers that manufacturers must have to test the tensile strength, stiffness, and brightness of the paper. To learn more about these testers and other crucial ones, visit the official website of UEC.
