          Film COF Testing Essentials for Quality Control Introduction Film COF testing plays a critical role in evaluating how plastic films behave during processing, packaging, and end-use applications. Manufacturers, converters, and quality control personnel rely on accurate slip data to ensure smooth performance on high-speed packaging lines and to confirm product consistency.
