Building a Stable Degassing System 18 Series Enhances Packaging Quality

21 Aug 2025

In industries such as coffee, pet food, and fermentation packaging,where precise gas regulation is essential one way degassing valves have become an indispensable component. As a manufacturer specialized in the research and production of degassing valves, WOJIN has launched the 18 Series, which has gained wide recognition from packaging manufacturers and brand clients for its stable performance and diverse specifications.

The WJ18 Series includes two models: WJ1801-FB and WJ1802. The key difference between the two lies in the presence of a filter screen—WJ1801-FB comes with a built-in filter, while WJ1802 does not. Valves with filters are suitable for granular and powdery products, whereas those without filters are only suitable for granular materials.

The biggest difference between the WJ18 Series and existing one way degassing valves lies in size. To meet the diverse size requirements of different customers, we developed the WJ18 Series. Our one way degassing valves are made from high temperature resistant and corrosion resistant materials, such as food-grade plastics, ensuring that no odors are released and no negative impact is caused to the coffee or pet food and other objection during long-term use.

The core advantages of this valve series lie in its strong sealing capability and stable air pressure. It effectively releases carbon dioxide, fermentation gases, and other internal gases, while preventing external air, moisture, and odors from entering, ensuring the freshness and quality of the packaged product. The WJ18 valves are compatible with semi-automatic and fully automatic valve applicator machines. Their design has been extensively tested and validated in the market, demonstrating reliable and stable performance even during transportation and long-term storage.

As market demands for packaging quality and functionality continue to rise, degassing valves are no longer seen as simple accessories—they have become key details that reflect a brand’s professionalism. Whether used for coffee export packaging or functional feed bags, the 18 Series offers excellent consistency and adaptability, making it ideal for long-term use in premium products.The 18 Series focuses not only on performance but also on refined design and craftsmanship, helping clients enhance the overall competitiveness of their products. We believe great packaging starts with attention to the smallest components.

We has always adhered to the philosophy of quality first, innovation driven, continuously optimizing product structures and manufacturing processes to deliver more efficient and reliable degassing valve solutions. As one of our core product lines, the 18 Series will continue to serve industries with high packaging quality standards through its outstanding overall performance.
