Why Do Coffee Bags Have Vents? In-depth Analysis of the Coffee Packaging in the Small “Secret”

Coffee consumption continues to grow worldwide, and how to keep the fresh flavor of coffee has become the focus of coffee packaging manufacturers. In the coffee bags we see every day, many packaging bags have an inconspicuous small device-vent. What is this used for? Meishida is an experienced manufacturer of custom coffee bags with valves. Today, we will discuss in depth: why do coffee bags have vents?

What is the Function of the Vent?

Prevent Gas Expansion and Protect Package Integrity

Freshly roasted coffee beans release carbon dioxide even after cooling, a process that can last for days or even a week or more. Without an air vent, the gas can build up inside the bag, causing the package to expand or even rupture. The air vent is designed to solve this problem. As a custom coffee bags packaging manufacturer, we understand the importance of packaging structure to protect the quality of coffee.

One-way Air Vent to Prevent Oxygen Reflux

The venting valve is one-way; it can release the gas inside the bag, but prevent the oxygen from entering. Oxidation is one of the main reasons why coffee loses its flavor, especially the roasted coffee beans, which are extremely sensitive to oxygen. Therefore, the design of wholesale coffee bags with valve can significantly extend the freshness period of coffee, so that the final consumer can experience a better taste.

Additional Effect of Smell

When customers buy coffee, they can squeeze the bags and smell the coffee through the exhaust valve to confirm its quality.

Types of Exhaust Valves and Application Scenarios

Different coffee products have different packaging needs. Common types of exhaust valves include:

• External valve (patch type)
• Built-in valve (heat seal type)
• Invisible exhaust valve (for aesthetic design)

As a custom coffee bags packaging manufacturer, Meishida can customize the type of valves suitable for different application scenarios, so as to achieve a balance between functionality and aesthetics of the packaging.

Why Do Buyers Prefer Coffee Bags with Air Vent Valves?
