What is Wax Paper?

Waxes have wide applications in the packaging industry for coating paper and cardboard. This is due to their sealing and water- and oil-resistant properties. To achieve this purpose, the packaging industries coat the paper with a thin layer of wax, usually paraffin wax or soybean wax. With the coating, the paper becomes resistant to moisture and grease. Now this paper is called wax paper. The wax coating acts as a barrier to protect the inside content. 

Applications in The Food Industry

The moisture and grease resistance properties make the wax coating suitable for various food products such as candies, bakery products, and candies. The wax coated paper is commonly available for wrapping items like bread, butter, or cheese, or trays used in the bakery. There are also wax paper liners in the market for separating food products such as meat, or burger patties. It is because of the wax paper packaging that you can enjoy your burger without it sticking to its wrapper. 

In addition, the wax coated paper is also suitable for packaging fresh yeast as it allows the carbon dioxide to escape and retains moisture for yeast. It is also used while reheating or baking the pizza. It prevents the pizza from sticking to the pizza pan. In short, it acts as a non-stick surface. However, care should be taken as it is unsafe to use wax paper above 425°F (218°C). 

Non-food Applications

Apart from common use in Food Packaging, they also have non-food applications. They are used in the cosmetics industry to separate layers of cosmetics. They also found their application in fabric packaging where they protect the clothes from tear and shear. The wax coating on paper is also done in the floral industry for wrapping bouquets and flowers. They are also put in the packaging of pharmaceuticals, electronics, and hardware to enhance protection.
