상품 특징

• Highly versatile: This adhesive strip-type exhaust vent valve is suitable for attaching to the surface of containers requiring one-way gas exhaust, such as coffee bags, food bags, packaging bags, pet food bags, kimchi jars, fermented feed bags, bio-fermentation bags, tin cans, and plastic cans. Its transparent design blends seamlessly with most packaging, maintaining a clean and aesthetically pleasing appearance. 30 pieces per sheet.
• One-way venting: When the gas produced by the items sealed inside the bag reaches a certain pressure, the gas can push the venting valve open from the inside out, venting excess gas outwards; when the pressure inside the bag decreases to an insufficient level to open the valve, the valve automatically closes. Furthermore, the valve will only open automatically when the pressure inside the bag is higher than the pressure outside; otherwise, it will not open, preventing outside air and water vapor from entering the bag.
• Easy to use: Our one-way degassing valve requires no heat sealing, has strong adhesion (adhesion 2.2 kg/inch, holding force ≥ 8 hr/kg/inch), is not easy to fall off, and can be used immediately after application, making it convenient and efficient.
• High-quality materials: This one-way degassing valve is made of 100% new food-grade PE raw materials, which are non-toxic, harmless, safe, green and environmentally friendly, and are well-made.
• Verify the freshness of your coffee: Using this one-way degassing valve helps ensure the freshness of your coffee beans. You can also smell the aroma of the coffee directly by squeezing the bag, which helps you better verify its freshness.
