How to Seal Coffee Bags

The right way to seal coffee bags will keep your coffee fresh and increase its shelf life. Learning proper sealing techniques also helps reduce waste and keep bags crisp. Here are a few easy steps you can take to properly seal your coffee bags:

Step 1: Press and Close the Bag

Start by pressing and closing the bag, firmly gripping both sides of the top fold. Make sure you press the crease at the top of the bag flat, as this will make sure the bag forms a tight seal.

Step 2: Heat Seal the Bag

Next, you’ll want to heat seal the bag. You can do this with a heat sealer, an iron or even a hair straightener. If using a sealer, press the heated side of the sealer on the top of the bag for 2-3 seconds until it has secured the bag shut.

Step 3: Check Your Sealing

Using your fingers or the sealer, try to pull open the seal. If it does not tear, your bag should be correctly sealed.


If you are looking to maximize the shelf life of your coffee, we recommend also de-gassing your bag. This can be done by poking a few small air vents in the sealed top of the coffee bag. This will slowly release any trapped gasses and allow more of the flavor and aromas to remain preserved in your coffee.

Tips for Sealing Coffee Bags

  • Clean and Dry: Make sure the bag is dry and clean before sealing to avoid moisture being trapped inside.
  • Proper Storage: After sealing and de-gassing your coffee, store it in an airtight container or cool area.
  • Label Your Bag: Make sure to put the date and other details about your coffee on the bag so you remember the specifics.

Sealing your coffee bags correctly can help you get the most out of your coffee. By following these easy steps, you can ensure that your coffee bags are sealed properly and your coffee remains fresh as long as possible.
