19 Extrusion International 3/2024 New COF Indicator Simplifies Measuring Friction on Packaging Film  Tentoma, the manufacturer of RoRo StretchPack ® machines has introduced the COF indicator ST 1.0 tool to estimate if the coefficient of friction (COF) on the packaging film meets your requirements. It is a simple tool that can be used on-site by the service team or the operators on the packaging line. Doing a slide test with two film samples, the estimated COF value can be read from the integrated scale. If the value indicates an incor- rect coefficient of friction, the film supplier must be con - tacted. Film suppliers typically have access to measuring instruments for measuring the precise COF value follow- ing the ISO standard. This will clarify if the packaging film has the required COF value. The right COF value on the packaging film is crucial for optimal performance and reaching the maximum capacity of a packaging machine. However, the COF on a film roll can differ from the supplier's specifica- tions. This discrepancy often goes unnoticed until the film roll is installed, leading to packaging machine failure. Therefore, when experiencing repeated pack - aging failures, it's always recommended to verify the COF of the packaging film. It is to help in such situa- tions that Tentoma has introduced the tool COF indi- cator ST 1.0. The COF indicator ST 1.0 is a simple slide tester tool de- signed quickly to estimate COF on packaging film. The tool only estimates the COF value but is more affordable than a more precise COF measuring instrument follow- ing the ISO standard. Thus, the CF indicator allows man - ufacturers with a packaging line to measure the friction on the packaging film, to clarify if this is an issue.
