Food packaging typically uses several types of paper, each with specific properties depending on the food item and the packaging's intended purpose.

The most common types of paper used in food packaging include:

Kraft Paper: Known for its durability and strength, Kraft paper is often used for packaging dry foods, such as cereals, flour, and snacks. It’s made from wood pulp and retains its natural brown color, though it can be bleached to create white versions.

Greaseproof Paper: This type of paper is treated to resist oil and moisture. It’s commonly used for packaging items like fast food, sandwiches, pastries, and baked goods, preventing grease from leaking through.

Coated Paper: Coated papers are treated with a thin layer of plastic or wax to make them moisture-resistant. These papers are often used for packaging items like juice boxes, frozen food, and takeout containers. They help provide a barrier to keep the food fresh and prevent contamination.

Glassine Paper: A smooth, glossy, and air- and water-resistant paper often used for wrapping candies, cookies, or other confectionery items. It prevents moisture from getting in and protects the food from contamination.

Parchment Paper: This paper is treated to be non-stick and heat-resistant, making it ideal for cooking and baking, like wrapping fish or roasting vegetables. It’s also used in some food packaging for its ability to handle high temperatures without breaking down.

Wax Paper: This paper is coated with a layer of wax, which makes it moisture-resistant and non-stick. It is commonly used for wrapping food like cheese, sandwiches, and baked goods, but it’s not as strong as greaseproof paper.

Paperboard: A thicker paper used for items such as cereal boxes, frozen food packaging, and takeout containers. It can be coated or laminated to enhance its durability and barrier properties.

Carton Board: Often used for large food items like beverages (e.g., milk and juice cartons) or ready-to-eat meals, this board is made from layers of paper pulp and can be treated with a coating for moisture and leakage resistance.

Each of these paper types offers different benefits in terms of strength, moisture resistance, grease resistance, and ability to handle food without contaminating it. The choice of paper depends on the food's characteristics and the packaging requirements.
