How Do Coffee Pouches with Degassing Valve Help Coffee Sellers
In the world of specialty coffee, the road to the ideal cup doesn't end at the roaster. The last and most important stage is packaging, which protects the rich flavours and smells that develop during roasting. Without it, air and moisture quickly ruin the quality, making the coffee taste bad and making customers unhappy. At MTPak Coffee, we give roasters high-quality, eco-friendly packaging options that help them do their jobs better. The degassing valve is the most important part of this mission, as it makes sure your product gets to you in perfect condition.
This article will talk about the science behind degassing valves, the real benefits they may bring to your business, and how to choose the best pouch for your brand that has a valve.
What Is a Coffee Degassing Valve?
A coffee degassing valve is a small, one-way mechanism built into a coffee bag. Its sole purpose is to act as a pressure regulator. When coffee beans are roasted, they release carbon dioxide (CO₂) gas for several days afterward, a process known as "degassing." This valve allows CO₂ to escape, preventing the bag from bloating or bursting.
The valve's importance is its ability to solve a packaging dilemma — it lets the gas leave while also keeping oxygen and moisture from getting in. Oxygen is one of the main things that makes coffee go bad, ruining its taste. This one-way design can keep the best internal environment, and further help maintain the coffee's taste and smell.
Which Pouch Styles Best Integrate Degassing Valves?
You can use degassing valves in almost any type of pouch since they are so flexible. This means you are able to choose the right format that fits your brand and functional needs.
1. Stand-Up Pouches
Stand-up pouches have a built-in bottom gusset that keeps them upright, making them look great on store shelves and making for a great unboxing experience for online shoppers. There is often a zip that may be closed again to keep things fresh after opening.
2. Flat Bottom Coffee Bags
These high-quality pouches have a wide, solid base and up to five panels that can be printed on for high-impact branding. They give a luxurious, handcrafted look on the shelf, making them perfect for flagship single-origins or limited editions.
3. Side Gusset Coffee Bags
These are simple, useful designs that work well for larger amounts such as 1 kg for cafes. The side gussets can stretch to hold more things, but they won't change the shape of the bag, so it's easy to store and ship.
4. Kraft Coffee Bags
If you want your business to look natural, organic or rustic, the kraft paper pouches with a degassing valve are a wonderful solution. They are good for the environment and make good modern packaging. To make them completely compostable, you can line them with eco-friendly materials like PLA (polylactic acid).
How Does a Degassing Valve Help Coffee Sellers?
Buying good coffee pouches with a degassing valve will directly improve your business's efficiency, brand image, and sales. The benefits are evident and can be measured.
• Faster Time to Market: Package beans the same day they are roasted instead of waiting days. This makes it easy to fill orders and get your freshest goods to customers and stores faster.
• Longer Shelf Life: Valves slow down oxidation, which keeps the flavour and smell you want for a lot longer. This keeps the quality the same all the way down the supply chain.
• Less Waste: Valves limit things from getting too big and breaking seams during shipping, which saves money on damaged objects and packing.
• Better Brand Image: A valve on professional packaging demonstrates that you care about quality, which makes your brand look better. If you sell fresh coffee, people are more likely to become devoted clients and tell their friends about your business.
How Do I Choose the Right Valve and Material?
Choosing the appropriate parts is very important for performance. The size of your bag and the roast profile should match the valve capacity. Darker roasts usually need valves with more capacity because they emit more CO₂.
The right material is just as important; barrier properties keep things fresh. Here is a short comparison of several typical materials:
| Material | Key Properties | OTR (cc/m²/day) | WVTR (g/m²/day) | WVTR (g/m²/day) |
|---|---|---|---|---|
| MET/PE Laminate | High oxygen & moisture barrier | < 0.5 | < 0.5 | Dark roasts, long shelf life |
| KPET/PE | Good barrier, crack-resistant | < 1.5 | < 1.0 | Medium to dark roasts |
| PLA Laminate | Compostable, renewable | < 10 | < 8 | Eco-friendly light/medium roasts |
| Kraft/PE | Natural look, moderate barrier | < 15 | < 5 | Light roasts, short-term storage |
| Transparent PP/EVOH | Clear, high oxygen barrier | < 0.8 | < 2 | Whole bean premium visual packs |
Key Considerations:
• Valve Type: Standard valves can work with most whole beans, but high-flow valves work better with ground coffee or dark roasts.
• Barrier Needs: A low OTR (Oxygen Transmission Rate) and WVTR (Water Vapour Transmission Rate) keep things fresh longer. EVOH layers make it even harder for oxygen to get through.
• Sustainability: Compostable materials like PLA meet eco-standards (e.g., ASTM D6400), while recyclable choices fit with circular economy goals.
• Compliance: Make sure all materials meet FDA (21 CFR) and EU (EC 1935/2004) food-contact safety standards.
How to Open a Coffee Bag with a Valve?
It's easy to open a coffee bag with a degassing valve, but you need to know how it works. The valve doesn't open anything by itself. It's actually a little, flat circle or oval that is affixed to the bag. Just follow the normal steps for that sort of bag to open it.
1. Find the Tear Notch: Most coffee bags, even those with valves, have a small tear notch near the top seal.
2. Tear Along the Notch: Use your hands to rip the bag open at this point. You can use scissors to make the opening cleaner and straighter.
3. Look for the zipper: Most new bags will feature a zip lock, which is a resealable zip closure, immediately below the tear-off seal.
4. Open the Zip: To get to the coffee beans, pull the two sides of the zipper apart.
