What kind of paper is cardboard?

Cardboard refers to cardboard with a certain hardness, which is suitable for making cards. There are many colors.

Cardboard is a kind of thick paper with different thickness specifications. Cardboard with different thickness has different application scope. Although the cardboard is very thick, a piece of cardboard is still very thin and difficult to measure.

Therefore, to calculate the thickness of cardboard, it is usually to stack several pieces of cardboard together, for example, take out 100 pieces of cardboard with the same thickness and put them together, then measure the thickness with a ruler, and then divide the whole thickness by 100 to get the approximate thickness of cardboard.

Paper jam function:

The thickness of paperboard will affect its gram weight, thus indirectly affecting the tensile strength, toughness, bursting strength and tear index of paperboard.

Thick cardboard has different thicknesses to choose from, and cardboard with different thicknesses has different physical properties and uses. When choosing the thickness of cardboard, it is mainly based on demand and actual use to choose the appropriate thickness, not the thicker the better.
