Types of Impulse Heat Sealers

Choosing the right impulse sealer for your immediate job is not as easy as it would seem. The success of your packaging project is heavily dependent on the quality of impulse heat sealer that you use. The two main things that you should consider when choosing a sealer for plastic bags are the quantity of what you are sealing and the items being sealed. The main heat sealers available in the market are the constant heat, double impulse and single impulse sealers.

The single impulse units are designed with a single Ni-Chrome wire fitted on the lower or upper jaw. It uses a round wire element or flat wire element of varying width. Double sealer units have elements on both the upper and the lower jaws of the machines. They are particularly useful for sealing thick materials, and can seal up to 20 mil of material.

In contrast to the impulse sealer units, the constant heat sealer is always available for use. It uses an electrical resistance heater mounted on the sealing bars; along with a thermostat and thermal couple that regulates the temperature of the machine.

Impulse seal heater units come in varying models – hand held, foot operated, sliding knife, tabletop and automatic among others. Hand held impulse units are particularly useful for sealing cellophane, clamshells, poly bags, etc. These bag sealers are available in a wide assortment of designs that can be customized to fit your business’s needs.

Sliding knife designs incorporate features similar to other impulse sealers in the market, with the only difference being the blade slotted into the handle. These impulse sealer units are useful for making your own flat bags, hanging bags and static bags from poly tubing. On the other hand, automatic tabletop sealers feature adjustable timers that enable you to perform your sealing operations on schedule. They are very precise and produce a constant flat seal.

Similarly, automatic motion sealers generate more secure and identical seal motifs than the previous models. These impulse heat sealers units remarkably improve productivity and all you need to do is set the sealing temperature and seal cool-down time among other controls.
