These sealers have seal widths from 2mm to 10mm or with a round cut-n-seal wire. Use the wider widths for for the more robust liquid tight seals needed for food products. The round wires are usually used for cutting and sealing shrink wrap material. Regular hand impulse sealers are divided up by length of seal from 4"-12" , 14"-20" and 24" and longer. We also carry hand impulse sealers with cutters that have a cutting blade to trim the excess end of a bag off or for using tube stock. Our magnetic hold sealers have a magnet that holds the sealer down during the seal process. Double impulse sealers have a heating element on both sides of the bar and are used for sealing thicker materials. Models included in the Hand Impulse Sealers catagory start with FS, KF, TISH, AIE, PFS, WN, W and FSC
