GBC Pouch Laminators utilize pre-made pouches specifically designed for lamination purposes. The pouches consist of a clear plastic layer on one side and a heat-activated film on the other. To begin the laminating process, you simply place your document inside the pouch, ensuring it fits properly. Then, you feed the pouch into the laminator, which applies heat and pressure to seal the pouch and activate the adhesive film, resulting in a secure and professional lamination.
