wax paper

Wax paper is a moisture-resistant sheet material consisting of paper coated with a thin layer of food-grade paraffin wax or soy-based wax on both sides. Originating in the early 20th century as a food preservation and preparation aid, wax paper produces a smooth, non-stick surface that resists grease and moisture penetration. The wax coating typically melts at temperatures around 140–180°C (285–350°F), making it unsuitable for direct oven exposure at high heat, though it performs well in moderate-temperature applications and cold storage.

Wax paper serves multiple functions in the kitchen: it lines work surfaces and baking sheets to prevent sticking and facilitate easy cleanup, wraps sandwiches and baked goods for storage, separates layers of cookies, candies, and other prepared foods to prevent adhesion, and aids in rolling out dough by sandwiching it between two sheets. It is also used to cover dough during proofing, wrap chocolate for tempering, and line storage containers. While not suitable as a direct oven liner at high temperatures (unlike parchment paper), wax paper is invaluable for no-bake preparations, cold storage, and room-temperature baking tasks.
