Impulse sealers require no warm up time and seals by applying a pulse of energy to the sealing area, followed immediately by cooling. Impulse sealers only use power when the jaw is lowered. We recommend an impulse sealer for any thermoplastic material such as polyethylene (PE) or polypropylene (PP) which requires a lower seal temperature.
