L Bar Sealers are efficient and reliable shrink wrap machines with an ability to seal and cut two sides of film at once using an "L" shaped element. L-Sealers are easy to use, requiring minimal operator assistance with fully-automatic models. Manual and semi-automatic are also available. Many models are considered to be module and can be easily converted into shrink wrap systems that use an optional conveyor belt and shrink wrap tunnel. L-Sealers require Centerfold Film which comes off the roll folded at the back. Learn more about L-Sealers by calling a Factory Express at 1-800-399-2564. View Centerfold Film Selection.
