What Is COF (Coefficient of Friction), and Why Is It Important?

COF (Coefficient of Friction) is a value that represents the relationship between the force of friction and the normal force between two objects. While this might sound confusing, it is an important value for companies that manufacture lawn and garden bags and plastic bags for mulch. COF is important for both mailers and all lawn and garden bags that are palletized for transport and display.

Throughout daily life, friction occurs. This unseen force either allows or hinders the movement of two surfaces that come into contact. By controlling COF, companies that manufacture and sell plastic bags for mulch, mailers, lawn, and garden purposes can optimize performance and prevent problems specific to storage and transportation.
