Testing oil paper

The oil test paper is used to evaluate the paper's resistance to grease penetration. The principle involves applying grease to the paper surface and observing the penetration time and area, which reflects the paper's oil barrier performance. It is applied in quality control for products such as food packaging paper and greaseproof paper.
Selection
When selecting test oil paper, ensure the type of grease matches the actual grease in contact with the paper to be tested. Pay attention to the uniformity of the oil paper thickness to avoid affecting test accuracy. Choose specifications according to testing standards, ensuring compatibility with the viscosity range of greases commonly used in the laboratory.
