 | | Because corrugated cardboard is such a versatile packaging material, millions of tons are used each year to protect and display products. |
 | | Corrugated cardboard is a stiff, strong, and light-weight material made up of three layers of brown kraft paper. |
 | | After the corrugator has heated, glued, and pressed the kraft paper to form corrugated cardboard, the continuous sheet of cardboard is cut into wide box blanks that then go to other machines for printing, cutting, and gluing. |
