From tacos and burgers to candy and ice cream, almost all of your favorite guilty pleasure foods are presented in wax coated paper.
Why would paper need to have a wax coating?
A wax coating on paper creates a barrier for grease, water and odor. That is why you can enjoy your greasy burger without it soaking through the paper, or unwrap a taffy without it sticking to its wrapper.
How does the paper get the wax coating?
There are a few different processes for applying a wax coating on to paper.
- Wet Waxing or Wax Bath is the process in which a sheet of paper is immersed in wax.
- Roll-on or Dry Waxing is the application process in which one side of the paper is coated in wax by rollers.
- Laminating is the process in which wax is applied to printed paper and is used to bond two substrates together, such as foil to paper or paper to paper.
Paper can also be printed with a pattern of wax, which does not fully cover the paper itself. The roller used would have a pattern, such as honeycomb.
After the paper goes through the coating process, it is cooled by being run over one or more cooling drums. These drums instantly harden the wax so the paper can be rewound onto a ream. Each ream of paper is approximately 3,000 sq. ft. and contains anywhere from 2 to 30 lbs. of wax depending on what the end use would be. For example, butcher paper would have a heavier coating of wax than candy wrappers.
