Tissue paper is usually found in single sheets or sheet collections of 25, 40, or 50. White tissue is also sold specifically for bulk wrapping in reams of 480 sheets.
Some shops wrap delicate merchandise in folded or crumpled layers of tissue paper to protect it before placing it in bags or boxes for the purchaser. Facial tissue can be used for blowing one's nose after a sneeze.
Colored tissue paper can be used for an assortment of visually artistic purposes. For example, when wetted, the color bleeds a watercolor-like layer of tissue paper that stays when you peel off the tissue paper. Tissue paper can be crumpled up to form objects, such as flowers by crumpling it around the tip of a pencil.
For production tissue paper for wrapping is made by the machine glaze process. A slurry of fiber is placed on a forming wire where the water is allowed to drain away. The sheet is then pressed against a felt and pressed against a drying cylinder for the final drying step. The sheet is then pulled away from the dryer and wound up ready for further converting into wrapping paper.
