Curtain coating

Curtain coating is like coloring neatly with fancy markers on a piece of paper! Except, instead of markers, we use a machine that has tiny holes that pour liquid or thick paint onto a surface. The surface could be anything, like paper, plastic, or even a big metal sheet. The liquid or paint comes out from the holes and makes a smooth, even layer over the surface. Just like when you color with your fancy markers and make sure there are no white spots on your paper! The layer of liquid or paint dries up and becomes a very thin, even coating that can protect or decorate the surface. It's like a fancy way of painting or coloring!
