Coffee lovers are quite particular about the freshness of their coffee beans, and coffee bags with valve are designed to keep their best flavor. Individuals acquire the purpose of the valve upon purchase but do not necessarily have an idea about the right way to open it. This article is going to provide a complete overview, which includes use, design details, and packaging selection.
Why utilize a valve bag for coffee?
Coffee beans release carbon dioxide during roasting. If the bag is sealed tightly, it will bulge or even burst. A coffee bag with valve contains a one-way degassing valve in the bag so that gas is vented and air can’t be drawn in, to prevent the bag from bursting and prevent oxidation and flavor loss. For specialty coffee companies, not only does packaging in a coffee bag with a valve assure quality, it also enhances packaging quality.
How to Open Coffee Bag with Valve Correctly?
Find the Tear Notch or Cutout
Many valve bags of coffee have tear-off notches at the top of one or both sides that can be torn by hand.
Slowly rip or cut along the seal.
When it is heat-sealed and does not have a zipper, cut along the seal with scissors.
Do not damage the valve.
The valve is usually on the front of the bag. Cutting or tearing too low can compromise the airtightness. Sealing from the top is the way to do it, avoiding the valve area.
Why a Secondary Seal Is Important
For zippered coffee bags with valves, zip the zipper after each use. For zipless models, use a sealing clip or bean container.
How to Choose a Quality Coffee Bag with Valve?
- Material Safety: Food-grade composite film provides oxygen and moisture barrier.
- Stable Valve Performance: Valves are tested rigorously to enable effortless degassing and prevent back-inhalation of air.
- Printing and Appearance: Proper printing not only enhances brand image but also prevents ink contamination of the coffee beans.
- Various Sizes and Configurations: In various capacities (e.g., 250g, 500g, 1kg) and stand-up or freestanding zipper types, we can meet the needs of various coffee brands.
Tips to Improve Your Valve Coffee Bag Experience
- Seal within 24 hours of roasting in order to get the best out of the valve’s venting capability.
- Avoid high pressure during transportation to protect the valve from damage.
- Store coffee bags with valves in a light-free, humidity-free, and room-temperature-free place after opening.
- For valve coffee bags without a secondary seal, it is recommended to use a sealing clip.
