Impulse Sealing vs. Direct Heat Sealing – Your Questions Answered

We often get this question:  What is the difference between impulse sealing and direct heat sealing and how do I choose??

Impulse sealers – require no warm up time and seal by applying a pulse of energy to the sealing  area, followed immediately by cooling.  Impulse sealers only use power when the jaw is lowered.  **So if you are just sealing your every day poly bags, an impulse sealer will do the trick.**

a 5mm impulse sealer will do the trick for this poly bag

Direct heat sealers (constant heat) – maintain constant heat in both jaws.  Direct heat sealers use power as long as the machine is turned on.  As a result, direct heat sealers possess better heat penetration in order to seal thicker materials.   **If you are sealing thicker materials such as kraft paper or anything with gussets, go with a direct heat sealer.**

Gusset bags require direct heat sealers

How to Seal a Gusseted Bag?

Many of our customers call us asking what sealer works best for their gusseted bag.  Our blog, today, will address that question.

What is a gusseted bag?
Gusseted bags are commonly used in the coffee and tea industry.  The sides of the bags fold in to form a gusset.  Gusset bags have sides that expand, allowing you to package bulkier, larger items.

What type of sealer should you use to seal a foil gusseted bag?  Because of the gussets, a single element sealer such as your typical hand impulse sealer  cannot properly seal through all four layers of the gusseted bag.  Do not use a hand or foot or automatic sealer, not even a 5mm sealer.

We recommend using the following sealers:

6" Semi-Automatic Double Impulse Sealer

…this small unit is the perfect size for sealing coffee bags

Double Impulse Sealers
Double impulse sealers utilize two heating wires (upper and lower) to seal through your gusset bag.  We carry both hand and foot operated as well as a few automatic units to suit your produtction level needs.   Seal width – usually 5mm or 10mm (.20″  or .40″)

For more options, please see our website here.

Our most popular unit for sealing coffee bags

Direct Heat Sealers
Direct heat sealers (also known as constant heat sealers).  Whereas impulse sealers only create heat when sealer jaw and body meat, direct heat sealers maintain heat in the jaws as long as the sealer is turned on.    As a result, direct heat sealers possess better heat penetration to seal thicker materials.  Seal width – usually 15mm (0.6″)

Portable direct heat sealers  or clamp style sealers are affordable and easy to use.   We carry 6″, 8″, and 12″ models.

  • A temperature controller accurately controls the temperature from 30°-550° F (0°-300° C)

Foot or Table Top Direct Heat Sealers utilize a temperature controller.  Both units use a foot switch to control the movement of the upper jaw.

  • Band Sealers allow you to seal nearly any thermoplastic material considerably faster than any other sealer.

Seal quickly and efficiently with a band sealer

Vacuum Sealer
Sometimes, in addition to sealing a bag, you will require a vacuum.   We also carry a vacuum sealer made specifically for foil gusset bags (coffee bags).  The vacuum sealer is a double impulse sealer with a 5mm seal.

Seals and vacuums in one step!
