Friction parameters help the manufacturer understand how the finish of the blown film or printed carton can influence the feeding and running speeds. 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 (COF):
Static COF = Fs/N
Dynamic COF = 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.
COF can often be related to the feeding and running attributes of products, for instance UV varnished food cartons have a slip coefficient that is related to the formulation of the UV coating its cure and film weight.
Cartons that have a very low static coefficient of friction may have handling difficulties as they will tend to slide apart and are difficult to place into feeding hoppers.
In contrast, products which have a high COF will tend to stick together and can be prone to misfeeding due to multiple cartons entering the packaging line at once.
The Universal friction tester allows the user to test static and dynamic coefficient of friction with minimal training. Ultra-repeatable static COF; automatic sled placement with variable dwell times.
A fixed link between the sled and the load cell means that there are no errors in friction from pulley wheels or cords associated with other measuring instruments.
The UFT uses an intuitive touch screen user interface making it accessible and easy to use.
Pre-loaded ISO/ASTM/friction test methods with the option to create a custom test.
The UFT sled design makes the loading of film samples ultra-easy
This standalone instrument is designed for simple QA testing of static and dynamic COF. The instrument is preloaded with ISO/ASTM/friction test methods with the option to create a custom test. Included in the package are the attachments for performing peel, tear and seal strength tests.
Optional full analysis software allows for detailed statistical and graphical analysis of results, full PDF reporting and the creation of custom test routines.
Included attachments transform the UFT into a precision peel test instrument, accurately measuring the force required to separate glued or laminated films, tapes, labels etc.
Included tear strength attachment allows the user to measure and control tear strength to international standards.
Included test attachments for testing seal integrity of films or laminates.
The Universal Friction Tester software features graphical reporting of results and allows unlimited custom test routines to be created in minutes. Tolerances for both static and dynamic COF can be set for each test routine allowing for easy identification of non-conformances.
Multiple tests can be run per file and a graphical trace given for each. A master or reference file for the material
can be overlaid to give a quick visual comparison of batch to batch consistency and quality.
Full graphical and statistical analysis of test results can be printed to PDF for easy reporting.
The logo at the top of the report can be customised to reflect customer own branding.

Simple sample preparation with the Hanatek Universal Sample Cutter (USC) The Hanatek USC has been designed for the simple cutting of samples for the packaging industry. Additional 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.
The Rhopoint Universal Friction Tester has an optional detachable heated bed with temperature controller which allows tests to be conducted at a temperature up to 120°C. The sled placement pins can still be used with this attachment.
