Spray coating cardboard

Spray-coated paperboard is a process in which a uniform layer of coating is applied to the surface of paper using spraying equipment to form a specific coating. The principle involves atomizing the coating with air pressure and adhering it to the paper surface. This process enhances the paper's water resistance, wear resistance, or printability. It is commonly used for paper products requiring surface treatment, such as packaging boxes and book covers.
Selection
When selecting spray-coated cardboard, consider the basis weight and stiffness of the base paper to match the coating thickness requirements. Choose the type of coating based on its intended use, such as water-based paint for environmental friendliness or UV paint for fast drying. Observe the uniformity of the spray coating to avoid issues like orange peel or sagging. Test the finished product's folding endurance and adhesion to ensure it meets practical usage needs.
