Greaseproof paper, also known as parchment paper or baking paper, is a specialized type of paper with a protective coating that prevents the penetration of grease and oil. Here are the key features of greaseproof paper:

1. Grease Resistance: The primary characteristic of greaseproof paper is its resistance to grease, oil, and moisture. This property makes it suitable for various cooking and food packaging applications where protection against grease is essential.
2. Non-Stick Surface: Greaseproof paper typically has a non-stick surface, preventing food items from sticking to it during baking or cooking. This makes it a popular choice for lining baking sheets and pans.
3. Heat Resistance: Greaseproof paper is heat-resistant, allowing it to withstand baking temperatures without compromising its integrity. It serves as an effective barrier between food and the cooking surface, preventing direct contact with grease or oils.
4. Versatility: Beyond baking, greaseproof paper is used for wrapping and packaging greasy or oily foods, such as fried items, sandwiches, and fast food products. It helps maintain the quality and appearance of the food during storage and transportation.
5. Transparency: In some cases, greaseproof paper is transparent, allowing for easy visibility of the food inside. This is particularly useful in the food service industry where the presentation of the product is important.
6. Environmentally Friendly Options: Greaseproof paper is often available in eco-friendly and biodegradable options, contributing to its popularity as a sustainable choice for food packaging and preparation.
