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.
