Inclined Plane COF Tester - ToronCOF™ 2003
Static Coefficient of Friction Tester (Inclined Plane Method)
ToronCOF™ 2003 is an inclined plane coefficient of friction tester that measures the static coefficient of friction of packaging films, paper, paperboard, and related materials. The instrument uses the inclined plane method: a weighted sled rests on the specimen while the plane tilts steadily until the sled begins to slip. The static coefficient of friction is read from the slip angle, giving a direct measure of surface slip.
The ToronCOF™ 2003 suits materials where surface slip affects stacking, feeding, and stability, such as films, coated papers, and corrugated board. A touchscreen sets the test, and a built-in micro-printer and statistical analysis handle results at the bench. Adjustable sled mass and area let the instrument match different materials and test conditions.
The bed and controlled tilt keep the specimen flat and the slip angle repeatable, and safety protections guard the instrument during operation. Optional computer software adds data storage and reporting. The ToronCOF™ 2003 (Static Coefficient of Friction Tester, Inclined Plane Method) suits packaging, paper, and materials QC and R&D labs.
Inclined Plane COF Tester - ToronCOF™ 2003 Applications
The ToronCOF™ 2003 measures static surface friction where slip affects handling, stacking, and stability.
- Packaging Films: measures the static slip of films that must stack and feed without sliding.
- Paper and Paperboard: tests the slip of papers and board for stacking and palletizing.
- Corrugated Board and Cartons: measures the slip angle of corrugated for stable stacking and unit loads.
- Coated and Laminated Papers: checks the surface slip of coated and laminated paper.
- Films with Slip Additives: verifies the effect of slip and anti-block additives on static friction.
- Pallet and Unit-Load Stability: assesses slip between stacked layers for load stability.

Theory and Method
The inclined plane method measures the static coefficient of friction from the angle at which a specimen begins to slide. A sled of known weight sits on a specimen fixed to a flat plane. The plane tilts slowly and steadily, raising one end, until the sled overcomes static friction and starts to slip.
At the moment of slipping, the plane's angle is recorded. The static coefficient of friction equals the tangent of that slip angle, so a steeper slip angle means a higher-friction, less slippery surface. The measurement needs no pulling force, since gravity supplies the driving component along the incline.
Because the slip angle depends only on the surface pair and the tilt, the inclined plane method gives a direct, simple reading of static friction. A smooth, controlled tilt and a clean sled release matter for repeatable slip-angle values. The method suits packaging films, papers, and boards where surface slip affects stacking, feeding, and pallet stability.
