Cold lamination is a process used to protect and enhance documents, photos, and other materials without the use of heat. It involves applying a clear, adhesive film over the surface of the item, which is then pressed down to create a seal. This method is popular for preserving important papers and providing a waterproof barrier. Unlike hot lamination, which requires heat to activate the adhesive, cold lamination uses pressure to bond the film to the material. This makes it suitable for heat-sensitive items, ensuring they remain undamaged while still receiving protection from wear and tear.
