What Is Cobb Value and Why Is It Crucial for Paper Packaging Quality? Cobb value refers to the amount of water a paper or board sample absorbs over a specific period, typically 60 seconds. Measured using a Cobb sizing tester, this value helps determine the material's resistance to water penetration. A lower Cobb value indicates higher water resistance, which is critical for packaging materials used in humid or damp environments. Understanding the Cobb value is essential for manufacturers in industries like food, pharmaceuticals, and FMCG. It helps ensure that the packaging retains its strength and appearance even when exposed to moisture. By testing and optimizing Cobb value, companies can enhance the performance, durability, and shelf life of their packaging solutions, ultimately protecting the product inside.
