Filtered Packaging Valve (PE)

1. Filtered Packaging Valve (PE)

The filter-equipped packaging valve (PE) is a one-way vent valve used in packages containing products that release gas, such as roasted coffee. Its polyethylene body is highly compatible with PE-based packaging films and adheres firmly to the package. The filter layer inside the valve prevents coffee grounds from entering the valve during gas release, helping to maintain its airtight seal throughout its service life.

While carbon dioxide accumulating inside the package is released in a controlled manner, oxygen is prevented from entering from the outside. This prevents the package from swelling and helps preserve the coffee’s aroma and freshness throughout its shelf life.

Key Features:

• One-way operation: allows gas to escape, prevents air from entering
• Filtered design: prevents coffee grounds from clogging the valve
• PE body: fully compatible with polyethylene packaging films
• Raw materials suitable for food contact
• Compatible with automatic and manual valve installation machines

Applications: Packages of roasted and ground coffee, whole bean coffee packaging, and fermented product packaging.
