Co-Efficient of Friction / Slip
The successful processing of flexible films or paper and board is largely dependent on the correct coating of ‘SLIP’ additives applied to the material. The successful forming of the material requires easy sliding or flow over formers on the packaging machine where at high speed acute angles can change the direction of flow to produce a tube or pouch. The application of ink on the film, will cause the properties of slip to change, therefore the need to measure and control Coefficient of Friction is paramount.
Applicable to all methods of product packaging machines including: Over wrap, H.F.F.S. and V.F.F.S. Slip measurement of material against material with values between 0 and 1, Static and Dynamic.

Touch Screen Precision Friction Tester for determining Static and Kinetic Friction of packaging materials to ASTM, BS, ISO and TAPPI standards
Slide Angle Friction is a measurement of the angle of inclination at which one substrate affixed to a sled will begin to slide/slip against another substrate of a similar material.
This Coefficient of Friction / Peel Tester uses advanced digital force signaling and high-speed data acquisition software to provide precision and repeatability in COF and peel testing.
The Lab Master® Slip and Friction Tester with Elevator System is designed to precisely determine the friction characteristics of a variety of materials. The instrument removes operator variability from the test procedure with specially designed features to control sled placement rate, orientation/angle, dwell time, and removal.
