Waxed paper is paper that has been coated with wax to help keep things safe and secure. It's like a special paper that has a protective layer on it. This can be very useful for things like wrapping up sandwiches or snacks, or for keeping food fresh in the fridge. The wax helps keep out air and moisture, which can make food go bad faster. Plus, the wax also makes the paper stick together so that things don't fall out.
You might have seen waxed paper in your kitchen before. It usually comes in a roll like wrapping paper, and you can pull off a sheet when you need it.
One thing to keep in mind is that waxed paper should not be used in the oven or the microwave! The heat can melt the wax and make a big mess or even cause a fire. So, it's best to use waxed paper only for food storage and not for cooking.
Overall, waxed paper is a helpful tool for keeping food fresh and secure. Just remember to keep it away from heat!
