12" to 24" long foot impulse sealers with sliding cutter for sealing plastic bags and triming off the excess length. Can be used to seal tubing off a roll, opening the end of the roll with the cutter. These heat sealers for packaging come in seal widths of 2mm to 10mm. The Seal and Cut Models have a 2mm flat seal along with a round cut-off wire. Impulse sealers fire a short impulse of electricity through a specially designed heating element to seal the open end of bags. The length of the seal time will depend on the type and thickness of the bag being sealed as well as the type of sealer. Our sealers seal poly bags and any thermoplastic material such as polyethylene (PE) and polypropylene (PP) quickly and efficiently. Other materials also may be sealed. No warm up time is needed.
