Gummed paper is a type of paper coated on one or both sides with an adhesive layer activated by moisture. This type of paper is primarily used for labeling and packaging, as well as for other applications requiring an adhesive surface. When moistened, the adhesive on gummed paper becomes sticky and can be attached to various surfaces such as packages, boxes, or other items. Gummed paper is often used for sealing packages or envelopes, ensuring the safety and security of the contents. It can also be used for quick labeling and marking of objects, providing a convenient and efficient way of identification.
