How Can You Know The Stiffness Of A Fluting Paper

A fluting paper refers to the liner in the middle of the corrugated board, which can also serve as a protective packaging layer for products. It typically looks like a series of wavy lines that, pasted to the paper board, develops a corrugated box. 

The fluting is available in different sizes and weights and can be chosen based on the different requirements. The primary purpose of including fluting paper is to provide protection to the product inside via a cushioned support by filling up the vacant spaces in the exterior box. When selecting a durable and secure corrugated box, the stiffness property of the fluting paper is significantly considered. Manufacturers evaluate this stiffness using a Taber stiffness tester. 

Taber Stiffness Tester By UEC

The stiffness tester is designed to measure the stiffness and resiliency properties of the fluting or cardboard paper and other paper products, metallic sheets, plastic, and flexible materials. It comprises an oppositely-directional pendulum weighing system. It is a precise and responsive technique for determining the stiffness or resilience of the paper. Extremely lightweight and flexible, the tester comes with adjustable clamping jaws that can be adjusted to match and hold the specimen of any thickness. 

During the test, pressure is applied on the lower side of the sample using a pair of rollers. These rollers are attached to a driving disc which is located behind the pendulum. They push the sample and deflect it from the vertical placement. The pendulum applies an increasing force to the sample as it moves further from its position. When the pendulum mark aligns with the apt driving disc mark (that indicates the stiffing reading on the dial point), the test point reading takes place. The Taber stiffness units are shown the moment load is applied to the test sample. 

Conclusion

The Taber stiffness of the paper also determines the folding endurance of the paper, which could be evaluated using a folding endurance tester. Get in touch with UEC to source these instruments and more for your paper manufacturing business at the most competitive prices.
