Importance of Cobb Sizing Test in Packaging Industry
Water resistance in packaging materials is a crucial factor that determines the durability and usability of packaging solutions. Packaging exposed to moisture, such as corrugated boxes, cartons, and cardboard containers, must withstand varying environmental conditions without degrading. Pacorr's Cobb Sizing Tester effectively evaluates how much water these materials absorb under standardized testing conditions, providing accurate and reliable results. This information helps manufacturers select appropriate materials for specific packaging applications.
How Does Pacorr’s Cobb Sizing Tester Work?
Pacorr’s Cobb Sizing Tester involves a straightforward yet precise testing procedure. Initially, a test specimen is accurately weighed. It is then placed within a stainless-steel cylindrical container filled with water, where it remains immersed for a standardized period—typically 120 seconds. After immersion, the specimen is carefully removed and excess water is eliminated using a specialized stainless-steel roller included with the tester. The specimen is weighed again, and the difference between the initial and final weights represents the Cobb sizing value:
Cobb Value Calculation:
Cobb Value = Weight of specimen after water immersion – Weight of specimen before water immersion
The resultant value provides a clear measure of the material’s water absorption capability, essential for maintaining quality control and ensuring compliance with industry standards.
