Will wax paper absorb grease

Wax paper is not designed to absorb grease; instead, it provides a moisture-resistant barrier that prevents grease from soaking through. While it can resist some amount of grease, it is not greaseproof. Therefore, while wax paper can be used to separate greasy foods, it may not be the best choice for items that are very oily, as the grease can still seep through over time. For better grease resistance, parchment paper or wax-coated paper might be more effective.
