What is Clay Coated Paper?
Clay coated paper, also known as clay-coated board or clay-coated kraft paper, is a type of paperboard that has a thin layer of clay applied to one or both sides of a paper pulp sheet. This unique process enhances the paper's strength, durability, and printability, making it an ideal choice for various packaging and printing applications.
History of Clay Coated Paper
The concept of clay coated paper dates back to the early 20th century, when paper manufacturers first experimented with adding clay to the papermaking process. Initially, clay was used as a filler material to improve the paper's opacity and brightness. Over time, the process evolved, and clay-coated paper became a staple in the packaging industry due to its excellent printability and durability.
