Waxed paper is coated with a thin layer of wax, providing a moisture-resistant barrier. This type of food packaging paper is commonly used for wrapping sandwiches, lining shelves, and protecting food from humidity. While affordable and readily available, waxed paper is not heat-resistant and should not be used in ovens or for high-temperature applications.
The Non-Stick Wonder of Parchment Paper
Parchment paper is coated with silicone, which gives it non-stick properties and heat resistance. This makes it a favorite among bakers and cooks for lining baking sheets, wrapping food for steaming (en papillote), and preventing food from sticking to surfaces. Parchment paper is a versatile and reliable option, though it can be more expensive than other types of food packaging paper.
Coated Paper Options
Coated papers are treated with substances like polyethylene (PE) or polylactic acid (PLA) to enhance their barrier properties. PE-coated paper is water resistant making it a great solution for beverage cups. PLA coating offers compostability.
Other Specialized Papers
Beyond these common types, there exist a range of specialized food packaging papers designed for specific applications. Aseptic packaging paper, for example, is used for long-life food products like milk and juice, providing a sterile environment that extends shelf life.
