GB/T 22805.2-2008 "Paper and board — Determination of grease resistance — Part 2: Surface repellency method" specifies the method for determining the grease resistance of paper and board using the surface repellency method, which is suitable for evaluating the ability of paper surfaces to repel grease. By applying standard grease reagents onto the surface of test specimens and observing the penetration or diffusion of grease within a specified time, the grease resistance level is determined according to grading standards. The standard clarifies requirements for specimen handling, reagent selection, and result evaluation, providing a basis for assessing the grease resistance performance of paper used in applications such as food packaging.
