Two Coatings, Two Jobs
Grease-resistant paper is treated so oil cannot soak through the fibres. Wax-coated paper adds a physical wax barrier on the surface, which also resists moisture. Both keep oil off your counter; only one handles condensation well.
When to Choose Grease-Resistant
Pick grease-resistant stock for dry or lightly oiled foods that need to breathe — pastries, bread, and baked goods that go soggy when steam is trapped.
When to Choose Wax-Coated
Pick wax-coated stock for wet or heavily oiled foods, and anything that has to survive a delivery bag. The wax barrier keeps both grease and moisture where they belong.
