Coefficient of Friction (COF)
COF Tester
COF Tester CloseupCOF TesterCOF Tester - CalibrationCOF Tester

Summary : Flexible packaging is usually done on Vertical or Horizontal Form-Fill-Seal (FFS) machines in which the roll of film or laminate comes in contact with itself or other metallic /non-metallic components of the FFS machine. The contact generates friction which can inhibit the material to run properly on the machines and achieve desired production speeds.

Measurements of frictional properties may be made on a film/laminate when sliding over itself or over another substance (usually stainless steel).  

The amount of friction required to be overcome to initiate motion is called as the Static Coefficient of Friction and the amount of friction required to be overcome to continue the motion is called as the Kinetic Coefficient of Friction.

Applicable to : Plastic Film and Laminates. 

Test Method : A sled weighing 200 ± 5 g is wrapped around with the test specimen and made to slide over a similar substrate or stainless steel surface with a speed of 150 ± 30mm/min. The initial and average drag force (in grams) is recorded and divided by the sled weight (200g) to calculate the static and kinetic COF respectively.
