Paper and paperboard products need the right amount of friction to work properly in packaging, printing, and manufacturing processes. Too much friction can cause jams and tears, while too little can lead to slipping and poor handling. TAPPI T 816 measures the static coefficient of friction (COF) using a slide-angle method where your paper sample…

Corrugated boxes and solid fiberboard containers form the backbone of modern packaging operations, but their performance depends heavily on surface friction properties. Whether boxes slip during transport, jam in packaging equipment, or stack properly in warehouses comes down to their coefficient of friction values. TAPPI T 815 measures the static coefficient of friction for corrugated…

Paper and paperboard products need the right amount of friction to work properly in your packaging and printing operations. Too much friction causes jamming and tearing, while too little friction leads to slipping and misalignment. TAPPI T 816 measures the static coefficient of friction (COF) of paper and paperboard using a simple inclined plane method…

When you need to measure how easily paper or paperboard slides against surfaces, TAPPI T 549 provides the industry standard method for determining the coefficient of friction (COF). This test uses the horizontal plane method to measure the force needed to move one material across another at a constant speed. The test is essential for…
