Tensile Strain Measurement in Recycled Paperboard Grades
Recycled paperboard strain measurement requires direct optical extensometry under ISO 1924-3 to isolate true sheet elongation from clamp slippage.
Downgauging Economic Model
Cost Equation
Financial analysis frameworks calculate the net savings achieved by reducing the thickness of packaging paperboard while maintaining necessary performance standards. This analytical approach, known as the downgauging economic model, balances the reduced material purchase cost against potential increases in production risk and wastage. By systematically lowering the caliper of the substrate, converters can reduce the tonnage of fiber purchased for a given production run.
This reduction directly decreases shipping costs and raw material expenses, making the product more competitive in high-volume consumer goods markets.
Financial Yield
Yield calculations must account for the higher price per ton often charged for high-strength, low-caliper specialty boards. When a packaging manager applies the downgauging economic model, they calculate the exact break-even point where the fiber savings outweigh any premium pricing of the replacement material. Savings on freight and carbon taxes also enter into the calculation of long-term profitability.
Risk Factor
Operational losses due to lower stiffness can erode these financial gains if the lighter board causes filling line stoppages. A downgauging project that reduces board thickness by ten percent might save five percent in material costs but lose more than that in slower run speeds and increased carton damage. Thus, the model must include stiffness thresholds.
