This is one of the most frequently asked questions by brands and technical teams when introducing degassing valves. The answer: If the right valve is selected and properly installed, it will not only maintain sealing integrity but also improve packaging stability and preservation performance.

The PE One-Way Degassing Valve is a plastic valve specifically designed to allow gas to escape in one direction while blocking outside air from entering the package. It is commonly used in packaging for coffee beans, powdered foods, and fermented products.

PE (Polyethylene) is a recyclable plastic material, but actual recyclability depends on the following factors.

With the growing emphasis on sustainability and plastic reduction, biodegradable materials and mono-material designs have become mainstream in packaging. While traditional degassing valves are often made from durable plastics like PP, PE, and silicone, more eco-friendly alternatives are emerging to meet the demand for green packaging.

As global demand for freshness and packaging quality increases, the market for one-way degassing valves is steadily growing. The coffee industry is the most significant driver. According to the latest market data, global sales reached USD 270 million in 2022 and are expected to grow to USD 330 million by 2029 with a CAGR of 3.3%.

Durability plays a critical role in real-world applications, especially for packaging sensitive products such as coffee, fermented goods, and medical materials.
