A 20" sealing length is perfect for packaging a variety of different things including boxes, videos, pizzas, boxes of chocolate, soap and much more. The SealerSales W-500I and W-500IC I-bar sealers have an impressive 20" sealing length. While they can be used with 20" centerfold rolls of shrink film, they can also be used with smaller rolls as well. Both of these sealers can be used with PVC or Polyolefin shrink film and they can also be used to seal poly bags shut for packaging purposes. The W-500I uses a round element for sealing and cutting film in a single pass, ideal for shrink wrap, and the W-500IC has a flat sealing wire that seals the film shut and includes a cutter for removing excess film, which is perfect for bag sealing. These sealers feature an excellent build quality and include a roll holder, a film opener and a sealing bar. Both of these sealers work as soon as they are plugged in and don't require any time to warm up. They can be used with an optional heat gun or a heat tunnel. Buy yours today!
