Our KF-series of portable sealers are ideal for sealing small, irregular or extra long packages. A 5-15 minute warm up time is needed in order for these sealers to achieve the correct temperature. Constructed of durable metal with insulated handle grips, these sealers are ideal for sealing cellophane, coated aluminum foil, Kraft paper, and other thicker materials. We recommend this sealer for those who needs the additional length in their sealer. Also, included with each portable sealer is an insulated working stand to protect your working surface when the sealer is not in use. These are constructed of heavy duty high impact, ABS thermal plastic casting.
