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.
It is
important that you buy impulse sealers from reputable suppliers that are known
to provide high-quality equipment. You want to buy your heat sealers from a
supplier that has been in the business for a long time. Their experience will
enable them to provide you with adequate support if you experience any issues
with the machines.

order for you to find the best impulse
sealer units in the market, you should research on all the options
available by comparing the products offered by three or four suppliers.
