High whiteness: White card paper has A very high requirement for whiteness. The whiteness of grade A should not be less than 92%, that of grade B should not be less than 87%, and that of Grade C should not be less than 82%. Its high whiteness gives it a pure and white appearance, providing a clean base color for printing and clearly reproducing colors.
Good stiffness: The fiber structure of white card paper is tight and uniform, with strong bending resistance and outstanding stiffness. Even after processing procedures such as folding or cutting, it can maintain good flatness and is less likely to deform or lift, making it suitable for making packaging boxes and other items that need to maintain their shape for a long time.
High smoothness: White card paper is usually processed by calendering or coating, with a high surface smoothness. The paper surface is flat and must not have any paper defects such as streaks or spots. This enables the ink to adhere evenly, resulting in excellent dot reproduction during printing and clear, sharp graphics and text.
