Simple to use - No operator training ? Impulse Sealing System - Seals Uniformily - Every Time ? No Warm-up time necessary Timer for Sealing Control Can this machine seal foil or laminated bags? Yes, it is designed to seal any thermoplastic material, including Polyethylene, Polypropylene, and laminations containing foils, such as those used to package coffee, or those that reduce electrostatic charge that are typically used to package electronic components How big of a bag can I seal on this machine? In theory you could seal bags as wide as the seal element is. In practice, though, this would mean centering the bag perfectly onto the machine, something that is difficult to do if you need to seal many bags. Take the total heat element width, and subtract 1/2 inch ( 1 cm). That is the approximate width of the biggest bag you should seal on any given model. How do I figure the settings to seal my bags? Setup is an extremely simple procedure and should take no more than a minute or two. Before you begin read all machine documentation carefully as it includes important safety information. Plug in and turn on Sealer (if applicable). Set up sealing time knob to level one. Put bag in sealer and test. If the bag is not sealed increase sealing timer to the next level. Repeat the process until you get the minimum time necessary to seal your bag
