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.
We’ve created a quick and easy way to determine what sealer works best for your customer based on your customer’s bag type and material thickness. Remember: You are always welcome to call us with your customer’s bag information and we can help you determine what sealer works best!
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:

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″)
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″)
Band Sealers allow you to seal nearly any thermoplastic material considerably faster than any other 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.
