Usage
Duplex Board,also called Whiteboard,White paper with grey back. The base color is gray, and the front is a white coated surface, mainly used for printing and packaging.
Due to differences in material and coating thickness, Duplex Boards are divided into multiple grades, with common grades being AAA, AA, A, B, decreasing from high to low, with B being the worst, also known as uncoated paper or lightly coated paper. The Duplex Board is measured in tons, and each Grades is divided into multiple grams, including 200 grams, 230 grams, 250 grams, 270 grams, 300 grams, 350 grams, 400 grams, and 450 grams. The weight here represents per square meter per gram.
Our Duplex Board comes in different sizes and thicknesses, and can be laminated according to customer requirements.
