Product Description

How is Kraft Paper Made

Kraft paper products are made using the Kraft process, which, like other paper production methods, involves the chemical conversion of wood into wood pulp. The structural components in wood are lignin and cellulose. Since lignin doesn’t make good paper, it must be separated from the cellulose. To do this, wood chips are cooked in a “white liquor” made of sodium sulfide and sodium hydroxide. They break the lignin and cellulose apart, leaving solid wood pulp and a “black liquor”. The wood chips have now been turned to a pulp and are screened to remove any larger pieces. The pulp is washed to remove any residual cooking liquors and can then be formed into various paper products.

Why is Kraft Paper Better Than Regular Paper

So how does the kraft process compare to other paper production methods? First and foremost, kraft paper is stronger, due to its reduced lignin content and high sulfur ratio. It also doesn’t involve extensive bleaching, which decreases the paper’s strength and increases manufacturing costs.
