Choosing the appropriate sealer for the job at hand is important. Choose the incorrect one and your packaging operations will grind to a stop. What you're sealing and the number of require to be done each day or per hour will be the identifying consider the sealant you eventually purchase. The basic types of sealers are single impulse, double impulse and consistent heat. Single impulse units use a single piece of Ni-Chrome wire mounted either in the upper or lower jaw of the sealant to produce the desired seal. Single impulse units use either a round wire aspect or a flat wire component of numerous widths. Round wire aspects are typically utilized for what is called cut and seal operations such as dealing with shrink film.

Double impulse sealants simply what they sound like. These systems have a component in both the upper and lower jaws of the machine. Double impulse sealants are generally used in the sealing of thick products, usually up to 20 mil along with sealing foil bags.
Consistent heat sealers, as oppossed to impulse sealants are always on and prepared to go. The units use an electrical resistance heating unit mounted either in or on the sealing bars. The sealing surface area of these bars is usually created to yeild a cross-hatch pattern in the seal however is likewise readily available in a horizontal line pattern also. Temperature level on these systems is controlled by a thermostat and a thermalcouple is attached to one of the bars to turn power on and off to the heating units as required to preserve temperature level.

Automatic impulse sealants, like the hand ran units, are set on top of a table or workbench, however these units once the timers are set properly will run instantly without any input from the operator. The timers will manage when the jaw closes, how long the component wire is stimulated and then the cooling or caking time before the jaw opens back up. This produces the most consistant seals as it eliminates operator error. Most sealants of this type likewise have a manual override switch to make the system cycle between timer settings if required.

Depending on the impulse sealer you're thinking about and the material you're product packaging, you might need to decide on the seal width you require to make. Typical options are a thin, round wire seal and then the flat wire seals that can be found in 2mm, 5mm, and 10mm.
Impulse sealants are developed around the size of the aspect wire to be used. This indicates that the transformer mounted inside the unit is specifically created to power a certain component wire. The only interchangability is with the round wire and 2mm flat component wires.

Equipped with this information you should now have the ability to make a notified choice and choose the appropriate machine for your application that will carry out well and last a very long time.
