Product Overview
This food-grade bag valve is designed for flexible packaging, especially for coffee bags. Made from PE (polyethylene) material that meets food contact safety standards, this one-way PE valve helps keep roasted coffee beans or ground coffee fresh for longer. It allows carbon dioxide (CO₂) and aromatic gases to escape from the bag, while blocking outside oxygen from entering. By doing so, it slows down oxidation and prevents the rapid loss of flavour and aroma.
This coffee bag valve is suitable for bags of different sizes. The venting rate can be adjusted by the number of pressing holes made on the bag during production, giving you flexibility to match the valve's performance to your package volume and filling conditions.
Key Features
Food-grade PE material – safe for direct contact with coffee, tea, and pet food.
One-way exhaust function – releases internal CO₂ and trapped aroma, yet seals out external oxygen.
Adjustable venting capacity – the exhaust flow can be controlled by varying the number of holes pressed on the pouch, so the same valve model works for small or large bags.
Customisable colour – available in different colours to match your packaging design (MOQ applies).
Reliable sealing – maintains bag integrity and prevents leakage under normal storage conditions.
Applications
Coffee bags (whole bean or ground)
Tea bags and tea leaf pouches
Pet food bags (dry kibble and treats)
Other dry food or agricultural product packaging that requires degassing
