ActivePaper and board—Determination of internal bond strength（Scott type）
纸和纸板 内结合强度的测定（Scott型）
Application Summary AI generated
This standard specifies the Scott-type method for measuring the internal bond strength of paper and board, which quantifies the resistance to delamination or splitting within the sheet. It is applied in the paper manufacturing and converting industries to evaluate the internal cohesion of materials used in packaging, printing, and laminating, particularly for products like corrugated board and coated papers. The test is critical for quality control and process optimization, ensuring that paper and board can withstand stresses during converting, handling, and end-use without layer separation.
