Select a laminator that accepts the widest regular document and the pouch thickness needed for its intended use. A narrow unit may suit badges, photos, and letter-size material, while larger sheets require additional feed width. Pouch thickness affects stiffness and durability, but the machine must be rated for the chosen thickness. Consider warm-up time, operating speed, jam-release features, and whether several people will share the machine. The document should enter squarely with a sealed pouch edge leading into the laminator. Allow space behind the unit for the finished piece to exit flat. A laminator used for occasional certificates has different capacity needs from one processing repeated menus, signs, or reference materials.
