Defect Yield Rather Than Permeation Decides Contracts
Achieved yield on ultra-high barrier film runs near 58% of coated web area, and a single pinhole across a square metre renders that section unusable whatever the formulation achieves in a laboratory. Materials account for only around 23% of finished cost, so pricing on materials plus margin misprices the product badly. Suppliers with better permeation performance and lower yield lose contracts to competitors whose defect rate is simply better, and the customers are entirely right to choose that way. Yield improvement comes from accumulated process learning on the specific line rather than from equipment specification.
