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

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.

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.
