Paper is an important material used in a wide variety of applications, from packaging to printing. The quality of the paper can vary depending on the manufacturing process and the type of materials used. One important aspect of paper quality is the stiffness of paper, which can be affected by the presence of fillers, size, basis weight, and other factors. Testing the stiffness of paper is essential for determining its suitability for a particular application. The Presto stiffness tester is a precise and easy-to-use instrument that is ideal for testing the stiffness of paper.
This paper stiffness tester is one of the highly effective lab testing instruments that are also useful in measuring the stiffness to determine the resistance of paper and paper board to bending. With its user-friendly interface and accurate results, the Presto stiffness tester is essential testing equipment for any paper laboratory. Here in this blog, we are going to provide you with information about how you can easily measure the ability of paper to resist bending using the Presto stiffness testing instrument. Before that let us focus on the purpose of performing the stiffness test on paper. So, let us get started!
The stiffness of paper is typically defined in terms of the force, moment, angle, or length required to produce a given effect on a specimen of known dimensions when strained in a specified manner. For example, the bending stiffness of paper is commonly quantified in terms of the force required to bend the paper through a given angle under specified conditions. There are many different ways in which paper can be strained, and so there are many different ways in which the stiffness of paper can be quantified. Presto has come up with one of the effective lab testing instruments called stiffness tester which is highly useful in testing the stiffness of paper and paper boards.
Presto’s stiffness tester utilizes a two-directional pendulum-type weighing system to evaluate material stiffness, flexural strength, and resiliency and elasticity properties. Force is applied to the lower end of the specimen by a pair of rollers attached to the driving disc. The resulting torque tilts the pendulum from its vertical position and the Stiffness Unit reading (g/cm) is taken when the pendulum mark aligns with the appropriate driving disc mark (15°). Predetermined sample length, deflection angle, and rate of loading provide accurate and reproducible test results will be seen by performing stiffness test on paper. This lab testing instrument also offers durable construction.
With these features and technical specifications, it will be easy for you to determine the stiffness of paper and its related products. You can easily measure the bending resistance of card stock with the help of the Presto stiffness tester. This lab testing instrument will easily operate and comes with a corrosion-resistant body.
The paper quality will be affected by several factors and stiffness is one of them. Therefore, you can easily test the stiffness of paper with the help of this packaging testing instrument. This portable and highly precise lab testing equipment is highly useful in testing the creasing stiffness of paper effectively.
