What is Heat Sealer?

A heat sealer is a machine used to seal product packaging using heat. Continuous heat sealers utilize heated moving belts. Impulse heat sealers use a stationary heated element. Good seals are a result of time, temperature and pressure.

What is Impulse Bag Sealer?

The impulse bag sealer or impulse heat sealer uses a short burst of electricity flowing through a resistance wire to bring a poly bag (and many other types of materials) to their melt point and literally weld the two sides of the bag together.

An impulse bag sealer does not get hot when you plug it in. It remains cool until the jaw is brought into contact with the bag. There are several types of impulse bag sealers, characterize by their type of operation:

With any impulse bag sealer, the heating element timer must be set to produce a level of heat from the heating element that is sufficient to literally "melt" the bag material---for only an instant. The correct timer setting is critical to the successful operation of any impulse bag sealer. If the timer is not set long enough the seal will be weak and tend to burst open. If it is set too long it will burn the bag material and also produce an inferior seal. Specific instructions on how to properly set the timer on your Midwest Pacific impulse bag sealer can be found under the title "Tips", that can be found at the bottom of each page of our website.

Impulse sealers are fast, efficient tools to securely seal many different types of bag material. They are commonly used for polyethylene, polypropylene, PVC, many types of polyester and even many metallized or foil bags (provided they have a poly laminated liner).

Impulse bag sealers are NOT recommended for cellophane, laminated polypropylene or other cello-like materials that require a temperature set-point be maintained for fixed periods of time

Types of Heat Sealers?

Heat sealers come in wide variety for different applications. Please check below the complete range of heat sealers to find out which suits your needs...

There are two basic types of heat sealers. Automatic or continuous heat sealers use moving belts to keep up a continuous production line. Products are bagged, sent down the belt, sealed, and dropped into boxes for shipment or storage. Impulse heat sealers have a single element, and are usually designed to be operated by hand. In some instances, an impulse heat sealer is partially automated. Continuous heat sealers are much larger, and more expensive, because of their greater size and higher volume capacity. Impulse heat sealers range in price, with simple desktop versions being very affordable.

  5. Impulse Sealers with a Sliding Knife
  6. This unit has the same features of our other Impulse Sealers but incorporates a knife into the handle. This is a handy feature when you are making your own bags from a roll of poly tubing. After sealing, slide the knife across the film to cut the film from the tube. This puts a uniform �� skirt on the bottom of the bag plus leaves the end tube open. The open end of the tube forms the opening of the next bag to seal..

  8. Create a secure, repeatable seal and increase your production rate. In fully automatic mode electronic controls allow you set the sealing temperature, sealing time, seal cool down time and idle time. In semi-automatic mode you control the idle time and start the sealing cycle with a foot pedal.

    Sealers FAQ's

    Making the Right Choice

    There are many types of sealers available. A brief summary on a sealer�s function, size, speed, and heating elements will help you determine the right sealer for your needs.


    There are mainly 2 types of sealers, an impulse heat and a direct heat sealer. The impulse heat sealer is used for any thermoplastic material such as a poly bag that requires a lower temperature. It can also be used to seal poly �coated materials. On the other hand, the direct heat sealer provides a higher temperature on heated jaws, so it is mostly used for cellophane and other thicker thermoplastic or poly-coated materials. Other functions to be considered in selecting the right sealer are cutter units, vacuum formation and gas purging.


    The size of sealer to use depends on the width of the material to be sealed. For easy handling, add one inch to the width of material to get the size of sealer needed.


    The portable sealer is lightweight, handy, very versatile and does not need a big work area. The sizes are limited.

    The hand sealer is the simplest and most economical. The sealing bar is manually lowered. This sealer is available from 4" to 40" Approximately 6 to 20 packages can be sealed per minute.

    The foot sealer provides a faster sealing operation. The sealing bar is pedestal controlled, leaving two hands free for faster operation. The foot sealer is available from 12" to 35". Approximately 8 to 20 packages can be sealed per minute.

    The auto sealer provides the fastest sealing operation. The unit has a continuous automatic motion at a pre-set time cycle or it can be placed in a manual mode and actuated by a foot switch for each intermittent cycle. Auto sealers are available from 12"to 24". Approximately 20-50 packages can be sealed per minute.

    The continuous band sealer provides very fast sealing operation with unlimited length.

    There are several models available with different features, such as horizontal seal head, vertical seal head, tilting seal head, left or right side feed, gas purging, coding and imprinting.

    Heating Elements for Impulse Heat Sealers:

    The heating element comes in round or flat. In most sealers, the round and flat wire can be interchanged. The round wire is mainly used for cut and seal. There is no seam left. Depending on the width of the flat wire element, sealers are available in 2-3mm, 5mm , 8mm, or 10 mm. Some sealers are equipped with two heating elements for faster heat penetration, ideal for sealing thicker materials.

    Standard Features of Impulse Heat Sealers

    The sealers are of metal construction, the body is formed out of a rugged cast aluminum and the pivot is all steel. The sealers are of industrial quality and built to last. Most sealers are equipped with plug-in electronic timer and built in micro-switch. No warm-up time is needed. Power is used only when the sealing bar activates the micro-switch. The variable timer let you seal various types and thickness of plastic films. A signal light and beeping sound come on to let the operator know the heat cycle is completed and the seal is done. The number in the model number usually indicates the size of the sealer in mm; so a 200 is an 8"and a 1000 is a 40". The letter in the model number is used to designate the manufacturer and type of sealer, such as H for hand sealer, and A for auto sealer. Divide mm by 25.4 to get its equivalence in inches.
