TISH-Series is our premium line of impulse sealers. Materials up to 40" wide and 10 mil thick can be sealed depending on the sealer model. A signal light and "beep" indicates the heat cycle is complete and the seal is done. Once the timer is set, hand sealers will provide a consistently flat seal that is air and water tight. Effectively seals Polyethylene, Saran, Nylon, Polyvinylchloride, Polypropylene, Pliofilm, Kel-F, Mylar, Polyflex, Polyurethane, and Polyvinyl alchol. Very Easy to use, no warm up time needed. Just place your film/bag between the seal arm, press, and release.
