Best Practice: What the Heck Does Congeal Mean?

CONGEAL MEANS TO COOL UNDER PRESSURE.

Document-2-page001

Hand / Foot Impulse Sealers
The hand or foot sealer is a manual sealer. What this means is that the congeal step or dwell step needs to be added into your sealing process to make a proper seal.    Hold the jaw down for a couple of seconds after the timer light has gone off to set the seal.  This will ensure a proper seal and will also allow the sealer to cool down before the next seal.  This will ensure longevity of the heating elements.

Auto Impulse Sealers
We recommend the congeal (cooling) setting to be at least 2x greater than the heat setting.  This will ensure that the seal has ample opportunity to set and cool under pressure.  This will also allow the heating element to cool as well.  The most important step for the longevity of auto sealers is having the appropriate congealing time.  Most customers skip the congeal setting in order to get a higher ppm (packages per minute) but this will only lead to problems – broken element and PC Board.

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!

We hope this provides you with some smart choices for sealing your gusseted bags.  Please be sure to check out our website – Sealer Sales.  Please contact us for more questions.
