What Is PE Coating Paper?
As the name suggests, PE coating paper is a paper roll coated with polyethylene to make the paper water and grease-resistant.
The coating substance (PE film) is heated up and made into a thin film no more than 0.04cm thick. The hot film is then pressed onto the surface of the paper board to create a layer. This process will make a tricky coating hard to strip off the paper.
So the resulting polyethylene-coated paper is water-resistant and sturdier, making it perfect for manufacturing all types of food packaging.
