Sliding friction is an important property to consider when selecting packaging films. The coefficient of sliding friction (COF) is a measure of the force required to move one surface in relation to another and is a good indicator of how easily the film will slide over itself or other surfaces. Thus, testing the quality of these films is very important to make sure that the right products will be delivered to the customers with ease. Presto has come up with one of the amazing lab testing instruments known as the coefficient of friction tester. The digital model of this lab testing instrument indicates the starting and sliding friction of plastic films and sheets when they slide over each other at a specified test condition.
