A Coefficient of Friction Tester is a device used to measure the static and kinetic friction between two surfaces. In the packaging industry, this tester is crucial for ensuring that materials, such as films, papers, and cardboards, have the appropriate friction levels to prevent slippage during transportation and storage. By accurately measuring the frictional properties, manufacturers can enhance the safety and stability of packaged goods, optimize material selection, and maintain consistent quality standards, ultimately ensuring the integrity of products during handling and shipping.
