Presto’s Co-efficient of friction tester is mostly used to evaluate the coefficient of starting and sliding friction of plastic sheets, papers, films, and pipes. It measures the kinetic and static friction of the test specimen when it slides over substance in a specified test situation. The test is done to evaluate the stackability of plastic sheets and films. These test procedures help plastic manufacturers to avoid accidents due to resistance in loading, packaging, and transporting materials. The uneven sheet thickness could result in enhanced friction, which leads to uneven strength.
Co-efficient of friction methodology replicates the degree of mistreatment a plastic film can successfully endure without affecting the contents. It is a very simple and easy to use instrument designed specially to authenticate the friction that subsists between two surfaces duly covered by the plastic material. In many types of plastic films, slip properties are generated by default due to additives.
