Why do coffee bags need air valves?

Keep your coffee fresh

The coffee has an excellent taste, aroma and appearance. No wonder so many people want to open their own coffee shop. The taste of coffee awakens the body and the smell of coffee literally awakens the soul.

Coffee is part of many people's lives, so it is important to offer fresh coffee to your customers and keep them coming back to your shop. After all, the satisfaction of your customers is just as important as the product you offer. Believe it or not, the way the beans are packaged and ground can make the taste stronger or lighter.

Ever wondered how to keep your coffee fresh from start to finish? That's where coffee grounds valves come in handy.

You've probably seen those holes on the back of your delicious coffee bag, what are they?

What is a coffee grounds valve?

The valve and the coffee bags fit together. The one-sided lid allows suppliers to pack delicious coffee beans immediately after roasting. After roasting, the coffee beans release carbon dioxide for several hours.

A valve built into the cover of the coffee bag allows the carbon dioxide to escape from inside the sealed bag without contaminating the outer surface. This keeps the coffee beans or ground coffee fresh and free of bacteria - exactly what you would expect from a coffee bag.

 

Why are valves on coffee bags so important?

It is very important to establish a starting point for carbon dioxide because, frankly, your coffee bag could explode in a customer's car on the way home. No coffee shop or newly established coffee shop would want their customers to experience that, would they?

As soon as you open this flap, all concerns about gas leaks disappear. The gas in the bag causes a continuous increase in pressure in the bag. Without valves, the bag can leak or tear. The valve allows the gas to escape from the bag, preserving the appearance of the bag, preventing product loss and ensuring a longer product life.

Is oxidation good for coffee?

The one-way valve is extremely important to guarantee fresh coffee for customers. They act as a barrier against oxygen, dust and dirty air entering the bag.

When the product comes into contact with oxygen, a corrosive process begins. Just as oxygen dissolves a peeled banana or a sliced apple, the same process begins in the coffee bean. This leads to stale coffee whose shelf life is sometimes shortened from several months to a few days.

The one-way valve prevents oxygen from entering the bag, which keeps the coffee fresh much longer.

 

Why canned coffee does not need valves?

The coffee is degassed before canning so it can be stored for longer.

Most canned coffee can be thawed after grinding. This happens when carbon dioxide is released from the coffee after roasting, but in most cases it happens when the carbon dioxide is released while the coffee is out. If the coffee is left outside, it will smell and become contaminated. Worst of all, it's spoiled before it even gets into the can, so imagine what it will be like when it gets into your customers' hands.

One bad cup of coffee in the morning can ruin your whole day. It's important to ensure that you take the necessary steps to ensure the best quality product possible.

 

One-way coffee bag valves are the best solution.

They allow the coffee to be packed immediately after roasting. They have an easy outlet for carbon dioxide. They prevent the entry of contaminants. They eliminate the possibility of the coffee bag exploding. And above all, they keep the product fresh and delicious for the love and pleasure of your customers!
