A cold laminator is a device used to apply a protective layer of plastic film to documents and images without the use of heat. This process helps preserve the quality of the material, making it more durable and resistant to wear, moisture, and fading. Cold laminators are ideal for sensitive materials that could be damaged by heat, such as photographs or certain types of paper. These machines are commonly used in offices, schools, and print shops for various applications, including creating signs, menus, and ID cards. Cold laminators come in different sizes and models, catering to both small-scale and large-scale laminating needs.
