The friction is a very important feature for any packaging material. The friction offered by a packaging film decides the amount of force that is required to move it when it is in contact with another surface. Higher or lower coefficient of friction offered by a film may create problems related to the handling and transportation of the package. This is why the manufacturers must test the coefficient of friction for the plastic films. The coefficient of friction tester is a testing instrument that is widely used in the packaging industries for testing the coefficient of friction offered by various plastic films.
Testing principle for Coefficient of friction
The coefficient of friction is the ratio of the force that is required to slide a surface over another surface to the force that is exerted on the surface in the perpendicular direction of the surface. As this is a coefficient, it is a unitless quantity. The higher value of the coefficient corresponds to the higher amount of friction offered by the surfaces. Basically, there is two type of COF that is kinetic COF and static COF.
Conducting the Test
The test for the coefficient of friction is being carried out with the help of the instrument called the coefficient of friction tester. The instrument is designed to conduct the test according to the specifications that have been specified in different testing standards such as ASTM D 1894 which states the procedure for the testing Kinetic and Static Coefficients of Friction of plastic films and packaging sheets.
