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. Materials for impulse sealers: Polyethylene, Polyurethane, Polyvinylchloride, Pilofilm, Polyvinyl Alcohol, Saran, Nylon, bubble packs, padded mailers, foil, coated bags, Kel-F, Polyflex, Mylar, Tyvek, Surlyn, and other heat sealable materials.Features: Machine Model: E-KF-200HC. Simple to use - No operator training. Die-Cast construction. LED sealing power indicator. Adjustable timer for optimal seal control. Seals bags made of any thermosealable material. Cold cutting mechanism. No Warm-up time necessary. Machine Includes 2 Sealing Elements & 2 PTFE Sheets. Technical Specifications: 8 inch (200 mm) sealing length. 1/16 Inches (2.6 mm) wide sealing. Can seal poly material up to 10 mil thickness. Heat Time: 0-3.5 Sec. (Under 2 Seconds is recommended for most applications) Voltage: 110 VAC / 50-60 Hz. Plug type: NEMA 5-15P. Impulse Power: 260W (heat element does not heat while machine is not sealing, thus, energy draw is minimal) Shipping Specifications: Machine Dimensions: 12 1/2 Inches (320 mm) x 3 1/8 Inches (80 mm) x 9 Inches (230 mm) Machine Weight: 8 Lbs (3.63 Kg) Shipping Dimensions:15 Inches (390 mm) x 12 Inches (310 mm) x 7 Inches (170 mm) Shipping Weight: 10 Lbs (4.54 Kg)
