Stiffness is a key quality measure in paper production that shows how well paper resists bending. It's like testing how easily a sheet of paper flops over when you hold it horizontally. Paper makers need to control stiffness because it affects how paper performs in different uses - for example, paper for business cards needs to be stiff, while toilet paper should be more flexible. Similar terms you might see are "rigidity" or "paper strength." Measuring and controlling stiffness is a crucial skill in paper manufacturing, as it directly impacts product quality and customer satisfaction.
