We can offer both flexible packaging as well as heat sealing equipment for your coffee packaging.  Most of our pouches can also be purchased with a one-way degassing valve.  These valves help allow the natural build-up of carbon dioxide in freshly roasted coffee to escape while preventing oxygen, light or moisture into the bag.  There are various coffee bag options available – remember that foil bags will have the best barrier for preventing oxidation.

  • Foil gusseted bags are the most popular option and will stand upright when filled.  The bags have side gussets which can expand allowing you to package larger items.
  • Stand up pouches are gaining in popularity with coffee roasters; these bags have a bottom gusset which can allow the pouches to stand upright.  Our stand up pouches have a resealable zipper allowing your customer to reseal the bag once opened.
  • Enjoy the best of both worlds with our new square bottom gusseted bags. Now you can get the advantages of a traditional bag along with those of a stand-up pouch. Our square bottom gusseted bags allow even the lowest density product to sit narrow and sturdy on the shelves without ever worrying about tipping over.
  • If simple and inexpensive is what you are looking for, then look no further.  Flat pouches also known as pillow packs are widely used for office and restaurant service.  Ground coffee or powdered mixes can be packed in a pre-set portions to take the guesswork out of measuring each time you prepare a pot of coffee or any drink.

Once the pouch has been selected, the pouches must then be filled with your product and heat sealed to prevent the bags from being tampered with.  To seal your coffee bags, we offer a variety of heat sealing equipment that can meet your needs.  Whether you are just starting your production and looking for basic and affordable units or faster production volumes with the option to print a date code or expiration date on the seal line.

Remember that if you choose a gusseted bag, 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 a direct heat (constant heat) type of sealer.  Direct heat sealers will maintain constant heat in both jaws.

WNS-200D New Product

With its sleek and compact design, the WNS-200D is great for smaller work spaces.   Our WNS-200D is equipped with a digital timer which creates a consistent and reliable seal each time –  the sealing arm is easily activated and will not result in operator fatigue.  For additional units we recommend for coffee bags, please see here.

If you already have your bags and need a heat sealer option, we can test your bags on our sealers and send the samples back to you along with a video demo.  Just contact us!

We will be exhibiting at the upcoming Coffee Fest trade show August 19-21, 2018 at the Los Angeles Convention Center.  We are the sealing experts so stop by our booth #TT5 and see the sealers we recommend for coffee packaging.  Register at www.coffeefest.com/los-angeles with code 84231 to receive 50% general admission.

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.
