Air Exhaust For Coffee Bean Packaging 0.95g ±-0.03 White Coffee Packaging Valve Keep Coffee Fresh

Product Description : 

The traits of coffee packaging valves, also known as degassing valves or one-way valves, are designed to serve specific functions in preserving the freshness and quality of coffee beans. Here are some key traits of coffee packaging valves:

One-Way Functionality: The primary trait of coffee packaging valves is their one-way functionality. These valves allow gas, typically carbon dioxide (CO2) emitted by freshly roasted coffee beans, to escape from the packaging while preventing air from entering. This one-way flow helps maintain a controlled atmosphere inside the packaging to preserve the freshness of the coffee beans.

​

Pressure Relief: Coffee packaging valves serve as pressure relief mechanisms. During the degassing process, coffee beans release carbon dioxide gas, which can create pressure inside the packaging. The valve allows this excess gas to escape gradually, preventing the bag from swelling or bursting.

​

Preservation of Freshness: The main purpose of coffee packaging valves is to preserve the freshness, flavor, and aroma of coffee beans. By allowing carbon dioxide gas to escape, the valves help prevent oxidation, which can degrade the quality of the coffee beans over time. This preservation of freshness ensures that consumers can enjoy a flavorful cup of coffee.

​

Materials and Construction: Coffee packaging valves are typically made of food-grade materials such as polyethylene or polypropylene. These materials are durable, heat-resistant, and compatible with coffee packaging materials. The valves are designed to withstand the rigors of packaging and transportation while maintaining their functionality.

​

Compatibility with Packaging: Coffee packaging valves are designed to be compatible with various types of coffee packaging, including bags, pouches, and containers. They can be easily integrated into the packaging design during the manufacturing process, providing a seamless solution for preserving the freshness of coffee beans.

​

Customization Options: Coffee packaging valves offer customization options to meet the specific needs of coffee roasters and retailers. They come in different sizes, shapes, and designs to accommodate various packaging requirements. Additionally, valves can be customized with branding, logos, or product information to enhance the packaging aesthetics.

​

Environmental Considerations: Some coffee packaging valves are designed with environmental considerations in mind. Manufacturers may offer recyclable or biodegradable valve options to reduce environmental impact. These eco-friendly valves provide sustainable solutions for coffee packaging while preserving freshness and quality.

FAQ  : 

1. What is coffee One Way Degassing valve?

One way degassing coffee valves are vital to maximizing freshness by allowing freshly roasted coffee to degas in the package. Our one way degassing valves are industry proven to effectively and effectively vent CO2 gas build-up while sealing out environmental oxygen, moisture and contaminants.

2. Can the coffee valve customized to allow air to escape more quickly for larger package?

We can also custom fabricate valves to meet specific requirements.

3. Can one way degassing coffee valves be used under water?

We do not recommend that coffee one way degassing valves be used while immersed in water.

4.How TO install the  valve on the bags?

 We’ve invested in creating degassing valve applicator to meet customer’s need.

1. The valve applicator holds the die head in the correct position underneath the seat for valves.

2. It pressed down the die head by heat sealing the valve to the bag.

3. The pin pokes a tiny (can be 2~6) holes in the bag which the valve covers.
