Friction testing is used in the packaging industry to measure the slip resistance
of a product, with the aim of predicting feeding and running speed on an automatic gluing, erecting, filling or packaging line.
Friction parameters help the manufacturer understand how the finish of the blown film or printed carton can influence the feeding and running speed. Surface
slip is a key factor when printing, erecting or filling packaging materials on an automatic line.
A product’s slip resistance is characterised by it’s coefficients of friction:
Static = Fs/N
Dynamic = Fd/N
Where Fs is the maximum static frictional force and the Fd is the average dynamic frictional force. N is the Normal force, i.e. the force of gravity acting on the sample and test sled.
In practical terms, the static slip relates to the force required to get two resting surfaces moving, dynamic slip is the smaller force that is required to keep the surfaces moving once this initial “inertia” is overcome. These values are expressed as ratios and do not have units, they are usually quoted as a decimal value between 0 and 1.
The Compact Friction Tester (CFT) provides detailed information about the slip characteristics of packaging material. Surface slip is a key factor when printing, erecting or filling packaging materials on an automatic line. The CFT produces detailed force graphs that can be printed to a date/time stamped label as an optional extra.
Friction parameters help the manufacturer understand how the finish of a blown film or printed carton can influence the feeding and running speed.
A sample of 63.5mm2 with a weight acting over the entire surface area is moved on top of another sample at a given speed. Static and dynamic coefficient of friction are automatically calculated and displayed on screen. This is typically a face to face test.
Automatic sled placement with variable dwell times give more repeatable static slip results.
The Hanatek Advanced Friction Tester offers flexible testing to multiple standards and test types.
The Hanatek USC has been designed for the simple cutting of samples for the packaging industry. Dies can be configured to cut samples for most test types including: friction, tensile, grammage, O2 permeability, CO2 permeability, WVTR, rub resistance, carton crease, carton stiffness and many more.
