Pulse Sealing
What is Pulse Sealing technology?
If you ask our competitors, they’ll have you think it is the same as “impulse sealing.” We probably should have named this new sealing technology something else, however we named it Pulse, because it pulses. 
Pulse Sealing is way better than “impulse sealing.” The advantages of Pulse Sealing over impulse sealing are numerous with quality of seal our best feature. Other advantages include ability to use one machine to seal virtually all materials, speed in producing great looking seals, and reduced power requirements.
Pulse Sealing got its start years ago when a client challenged us to create seals comparable to RF, however without the headaches associated with RF. Impulse sealing was already available however neither comparable nor quite as good as RF. Additionally, at the time RF sealed faster and better than impulse sealing.
Gerald Lippman, one of the pioneers and original inventors of RF, and Glenn Lippman, physicist and one of the original inventors of wedge welding, a father and son team co-developed and filed patents on Pulse Sealing. Pulse Sealing combines attributes of RF and impulse sealing together with good old American ingenuity. Traditional impulse sealing applies lots of heat followed by cooling time under pressure. The lots of heat part tends to discolor the heat sealed materials. By pulsing the heat on and off, i.e., frequency modulation, each heat packet penetrates the materials to be sealed with a rate of heat absorption that quickens the sealing process without deforming or discoloring the materials. Cooler sealing means faster repetition which is more suitable for production.
Novaseal ShadeSealer-168
Recently we received a comment from Gilles Pepin, president of Decor Quebec Levis Inc. and owner of a Novaseal ShadeSealer-168. Gilles said one setting can be used for a variety of materials. Gilles’ production group uses the 168-inch wide format to automatically fold and heat seal many smaller shades of varying widths at the same time, and each of these shades are made of different materials; and one sealing parameter will seal everything, perfectly. He said he never had seen this phenomena in any other machine and learned that this phenomena is only made possible by Pulse sealing technology.
Pulse Sealing depends on frequency modulated heat absorption and each heat packet is absorbed at different rates, Multiplication of packets is absorbed by materials quicker resulting in reduced overall sealing time with shared/common parameters. Using Pulse Sealing, different materials will seal at their own rate but within the same time interval. So, even though our heat sealers include controls with multiple storage/recipe locations, most of our customers rarely use more than one setting for all their materials. Additionally, compared to impulse sealing, Pulse sealing uses quite a bit less power to achieve significantly better results. Pulse Sealing also compares favorably when compared to Hot Air sealing.

Since its inception, we’ve added Pulse Sealing to many of our standard machines. Today Pulse Sealing is an integral component in our ShadeSealer, PulseSealer, Table-Top Heat Sealer, QUAD Automatic, L-Pulse Sealer, BannerSealer, and Hand-Held Pulse Sealer. As a matter of fact, as a result of our success with Pulse Sealing, we no longer build heat sealers based on impulse or RF sealing methods.
Imagine how much more business you could do if your heat sealer has no limits and can seal all materials, and many different materials at the same time! Every Novaseal customer has increased their business revenues after purchasing a Novaseal ShadeSealer. Is it just opportunity or can buying a Pulse Sealer pay huge dividends.
