Like the white cardboard, the color is full and bright. Compared with the white cardboard, the stiffness is not as good as that of the white cardboard.
Kraft paper has high tensile force, high toughness, usually brownish-yellow, tear-resistant, and commonly used natural kraft paper with a thickness of 120 grams to 300 grams.

Whiteboard is a kind of cardboard with a white and smooth front and a gray background on the back. The commonly used thickness is 250g-350g. The whiteboard is white on one side and gray on the other. The price is a little cheaper than the white cardboard.
Black cardboard is characterized by fine paper quality, transparent black, firm and thick, good folding resistance, smooth surface, good stiffness, good tensile force and high burst resistance.
