Cold lamination is a process used to protect and enhance documents, photos, and other materials by applying a clear plastic film over them without the use of heat. This method is ideal for items that may be sensitive to heat, such as printed materials or photographs, as it preserves their quality while providing a durable, waterproof layer. The cold lamination process typically involves using a laminating machine or a manual laminating pouch. The item is placed between two sheets of plastic film, which are then pressed together to create a sealed, protective layer. This technique is commonly used in offices, schools, and homes for preserving important documents and artwork.
