Thermal laminating pouches feature helpful guides, thickness icons and directional arrows that disappear after laminating to deliver a crystal-clear finish while ensuring outstanding accuracy. Alignment guides on the pouch help you to perfectly center your item inside the pouch to easily create consistently even lamination borders. Thickness icons clearly identify the pouch thickness for proper laminator settings and quality finishing. Directional arrows on the pouch serve as a helpful reminder to ensure you always insert the correct edge first into your laminator, reducing misfeeds and jams. Ultraviolet protection prevents fading and discoloration over time to ensure the smooth, glossy surface always displays dynamic text and rich colors. Letter-size thermal pouches are designed for use with any laminator, including GBC Fusion laminators (sold separately).
