X100-COF coefficient of friction tester for packaging slip control.
A 1 kN X100-1 based COF system supplied with a 20 N load cell, FS1 friction slide and 200 g sled for static and dynamic friction testing of films, paper, laminates, coated board and packaging sheets.
For QA labs that need friction numbers tied to real packaging behaviour.
COF testing is most useful when the lab method matches the surface pair, travel length, sled mass and speed used for supplier comparison or line troubleshooting. This page keeps the setup visible so engineers can specify the tester without guessing.
- Static coefficient of friction for start-up slip, blocking risk and stack movement.
- Dynamic coefficient of friction for sliding behaviour during winding, filling, forming and handling.
- Film-to-film, film-to-metal, paper, paperboard, coated surfaces and printed packaging checks.
- Good fit for raw material approval, coating trials, supplier change validation and production QA.

Specify the method before specifying the fixture.
COF results change with sled mass, sled face, contact area, travel distance, speed, specimen backing and surface pairing. FITCO should confirm these details before the quotation, especially when different plants or suppliers are comparing results.
ISO 8295
Plastic film and sheeting method for determining coefficients of friction. Use this when plastic film slip is the controlling requirement.
ASTM D1894
Static and kinetic COF method commonly used for plastic film and sheeting, including film-to-film and film-to-metal comparisons.
TAPPI T549
COF method used in paper and paperboard workflows where sheet handling, coatings and surface finish affect converting performance.
ISO 15359 / JIS K 7125
Useful references when paper/board or Japanese film methods are required by customer specification or export documentation.
Force verification
Load cell verification can be aligned to ISO 7500-1 or ASTM E4 when the lab quality system requires traceable force calibration.
Routine QA output
Static COF, dynamic COF, peak friction force, average sliding force, method ID, batch data and operator/report traceability.
Information FITCO needs before locking the COF setup.
- Material pair: film-to-film, film-to-metal, paper-to-paper, board-to-metal or another surface pair.
- Required standard, sled mass, sled face material, contact area and test speed.
- Specimen size, specimen conditioning, backing plate requirement and surface orientation.
- Reporting format: static COF only, dynamic COF, pass/fail limits, batch export or full WinTest report.
