You also need to consider warm-up time, sealing width, bag materials and speed.Three Reasons You Should Use KF-Series Constant Heat Sealer:Constant heat (215F - 350F) in both jaws and use power as long as the machine is turned on. As a result, direct heat sealers possess better heat penetration and are very capable to seal thicker material.For materials such as coated aluminum foil, polycello films, gusset bags, coated Kraft paper, waxed paper, cellophane, mylar, coated PP, and other thicker materials. Applications like roasted coffee bag sealing, Kraft paper tea or standup pouch find KF sealer better suited than impulse.If sealing width is a consideration to you, you should go with constant heat sealer. Most direct heat sealer seals with 5/8-inches sealing width.

We usually recommend adding 1/2 - 1 inch to the width of material to be sealed for easier handling.Starter Kit, Warranty Decal and Extended 120-Day WarrantyTo help with business owner to understand mylar, we prepared a free starter kit. The starter kit will be shipped separately from sealer, together with the warranty.

It maintains constant direct heat in both jaws for better heat performance and penetration. - EXCEED WHERE IMPULSE FAILS: Impulse sealers seal by applying a pulse energy to the sealing area. We recommend an impulse sealer for any thermoplastic material such as polyethylene (PE) or polypropylene (PP) which requires a lower seal temperature. But becasue impulse doesn't maintain constant heat and sealing width is narrow, it's not recommended to use impulse sealer for thicker or gusseted coffee bag, stand-up pouches, metallized, Kraft paper bag or any coated thicker materials. - EASY TO OPERATE: 12" direct heat sealer equipped with two heated seal bars creating 5/8 in. (15mm) wide seal. KF-200CS is equipped with an adjustable temperature controller (Range 215°F - 350°F) giving the user a much wider range of temperature settings enabling a greater variety of material to be sealed. Sealer itself is constructed of durable metal with insulated rubber handgrips. Also included with each sealer is a stand.
