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:
…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″)
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)
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.

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.
When should you buy a band sealer? If you are finding that a hand or foot sealer cannot meet your production needs, a band sealer may be the right option for you. Band Sealers will seal and convey your bags via constant heat. Take a look at our video of how a band sealer works.
However, before deciding on a band sealer, ask yourself the following questions:
Q: Do you already have your bag? A: Make sure you have your bag before looking at sealers. The bag material will determine what sealer will work.
Q: Should you purchase a band sealer?
A: Our band sealers can seal materials 3mil-10mil meaning band sealers will seal just about any thermoplastic material including PE, PPE, stand up pouches, gusseted bags (used for coffee and tea), and moisture barrier bags. Because bags are placed on a conveyor system, the width of the bag does not matter. If you are looking for increased efficiency in your packaging process, then we recommend looking into a band sealer.
Q: What is the difference between a horizontal and vertical model?
A: Vertical band sealers typically seal small solid products (ex: powders, grains, coffee) and liquids. In addition, if your customer will be packaging his/her product using a stand up pouch, a vertical band sealer will work best. Horizontal models work best when you can lay flat your pouch.

Q: Do you want any printing on your bags? Dry-coding vs. embossing? A: Our band sealers have the ability to emboss or dry ink code bags. Embossing continually embosses characters directly on the bag. Embossing shows up best on foil bags. Dry ink coding prints using a roller with heat activated ink transfers.
Q: Is there a preference of production running right to left or left to right?
A: Our band sealers can seal in a right to left direction or left to right direction. Choose the right sealer based on your preferences.

When selecting a sealer, it is important to have a sense of the material which will be sealed. Try and have the material thickness and width available as this will make your selection process much easier. This will ensure the sealer you purchase is capable of sealing your material. If you want any sealer suggestions, fill out this easy questionnaire and we will provide you with some suggestions
This page discusses the four key characteristics of sealers to help you determine which best fits your application.
What is a heat sealer?
A heat sealer (ex: bag sealer, heat impulse sealer, direct heat sealer, hand sealers) is a machine used to seal plastic material using heat. There are many types of sealers and choosing the right sealer may be overwhelming without a few basic points.
Function
There are two main types of sealers: (1) impulse heat and (2) direct heat.
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. We recommend an impulse sealer for any thermoplastic material such as polyethylene (PE) or polypropylene (PP) which requires a lower seal temperature. Materials for impulse sealers: Polyethylene, Polyurethane, Polyvinylchloride, Pilofilm, Polyvinyl Alcohol, Saran, Nylon, bubble packs, padded mailers, foil, coated bags, Kel-F, Polyflex, Mylar, Tyvek, and other thermoplastic material. Impulse sealers are easy to use (no warm-up time), economical (electricity used only during sealing process), and safe (no component is always hot).
There are different types of impulse sealers based on type of material and usage:
Hand sealers can seal poly material up to 10mil thickness
Pedestal Type / Foot sealers can seal poly material up to 15mil in thickness
Auto sealers can seal poly material up to 15mil in thickness
Double impulse sealers (automatic and foot options) can seal poly material up to 20mil in thickness (We recommend double impulse for heavy duty applications)
Sealers w/cutters seal and trim excess material (tubing) in order to make customized bags
Direct heat (constant heat) sealers 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 roder to seal thicker materials. We recommend a direct heat sealer for materials such as coated aluminum foil, poly cello films, gusset bags, coated Kraft papers, waxed paper, cellophane, mylar, coated PP, and other thicker materials.
We also include other types of sealers used for more specific types of applications:
Vacuum sealers remove air from the product before sealing into an impermeable package. We recommend vacuum sealing in order to prevent oxidation, spoilage or corrosion. Barrier bags are used because PP and PE bags are both porous and cannot be used for long term storage.
The size of the sealer depends on the width of the material to be sealed. We usually recommend adding one inch to the width of material to be sealed for easier handling. Cutters on the sealer usually trim at slightly less than width of the sealer arm.
Speed
Portable sealers are lightweight, handy and versatile. Sizes, however, are limited.
Hand sealers are the most simple and economical unit. The sealing bar is lowered manually. Sizes are available from 4” to 40” and approximately 6-20 packages can be sealed per minute.
Foot sealers provide a faster seal than hand sealers. The sealing bar is pedestal controlled leaving your hands free. Sizes are available from 12” to 35” and approximately 8-20 packages can be sealed per minute.
Automatic sealers provide even faster sealing than foot sealers and are ideal for high production jobs. Automatic sealers are usually tabletop sealers whose jaws are activated automatically by a dial-controlled sequence timer. Automatic sealers feature a pre-set time cycle to allow for a fully continuous automatic operation. Automatic sealers can also be used with a foot pedal for semi-automatic operation. Sizes are available from 12” to 47” and approximately 20-50 packages can be sealed per minute.
Continuous band sealers provide the fastest sealing operation with an unlimited length. Bags are simply fed into sealer while resting on a conveyor belt. Several models are available with features such as horizontal seal head, vertical seal head, tilting seal head, left or right feed, gas purging, and/or coding and imprinting.
Width of Seal / Packaging Material
Heating elements are made of nichrome (nickel-chromium) and determine the width of the seal. There are two types of heating elements: round or flat which are interchangeable in most sealers. The round wire is mainly used to cut and seal with no excess material above the seal. 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 making them ideal for sealing thicker materials.
Standard Features of our Impulse Sealers
The all-metal construction of our sealers provides industrial quality strength and ensures lasting durability. The body is formed out of rugged cast aluminum while the pivot is an all-steel construction. Most sealers are equipped with a plug-in electronic timer and built-in microswitch. No warm-up time is needed. The variable timer let you seal various types and thickness of plastic films. A signal light and “beep” indicates the heat cycle is complete and the seal is done.
The number in the model number usually indicates the size of the sealer in mm; so 200 points to an 8″ sealer while 1000 points to a 40″ sealer. The letter in the model number is used to designate the manufacturer and type of sealer. For example, “H” signifies a hand sealer while an “A” suggests auto sealer.
