Waxed paper

Paper that has been made moisture-proof by the application of wax

Waxed paper, also known as wax paper, is a type of paper that has been coated with a thin layer of wax to make it moisture-proof. This coating provides a non-stick surface and makes the paper resistant to water and grease, which is why it is commonly used in food packaging and cooking.

History

The use of waxed paper dates back to the early 20th century. It was originally developed as a way to preserve food by preventing moisture loss and contamination. The process of waxing paper involves applying a thin layer of paraffin wax or beeswax to the surface of the paper. This innovation revolutionized food storage and packaging, allowing for longer shelf life and improved hygiene.

Manufacturing Process

The production of waxed paper involves several steps:

1. Base Paper Production: The process begins with the creation of the base paper, which is typically made from wood pulp. This paper is produced in large rolls and is the foundation for the waxed paper.

2. Wax Application: The base paper is then coated with a layer of wax. This can be done using a variety of methods, including dipping the paper in molten wax or applying the wax with rollers. The type of wax used can vary, but paraffin wax is the most common due to its cost-effectiveness and availability.

3. Cooling and Solidification: After the wax is applied, the paper is cooled to solidify the wax coating. This creates a smooth, non-stick surface that is resistant to moisture and grease.

Uses

Waxed paper is used in a variety of applications, primarily in the kitchen and food industry:

• Food Storage: Waxed paper is commonly used to wrap food items such as sandwiches, cheese, and baked goods. Its moisture-resistant properties help keep food fresh.

• Baking: In baking, waxed paper is used to line baking trays and cake pans to prevent sticking. However, it is important to note that waxed paper should not be used in the oven, as the wax can melt and potentially catch fire.

• Crafts and Other Uses: Beyond the kitchen, waxed paper is used in arts and crafts, as well as in various industrial applications where a moisture-resistant barrier is needed.

Comparison with Parchment Paper

Waxed paper is often compared to parchment paper, another type of kitchen paper. While both are used to prevent sticking, they have different properties and uses:

• Waxed Paper: Coated with wax, not suitable for oven use, ideal for wrapping and storing food.
• Parchment Paper: Coated with silicone, heat-resistant, suitable for baking and cooking in the oven.

Environmental Considerations

The environmental impact of waxed paper depends on the type of wax used and the disposal method. Traditional paraffin wax is derived from petroleum, which raises concerns about sustainability. However, some manufacturers are exploring the use of biodegradable waxes, such as those derived from soy or beeswax.
