Cobb–Unger oil absorbance test for paper and board
In this test, castor oil is used to evaluate the oil absorbance of a paper or board product. The test evaluates how well the product functions as packaging for oily foodstuff. During the analysis, oil is applied on top of the sample with an L&W Cobb sizing tester and the mass of oil that is absorbed by a set period is expressed as grams per square meter (g/m2).
