When you entered a market or a cafe shop, have you notice a small round button on some of the coffee bags on the display cabinet? It is called a one-way degassing valve and is commonly used on fermented food and coffee packaging. Degassed valves are usually made of high-density polyethylene (HDPE) material and are designed to periodically allow the internal gas to escape from a small valve on the package when the internal pressure exceeds a certain (small) value. As the name suggests, air cannot enter the bag from the outside (because it is a "one-way" valve), thus creating a sealed exhaust effect to keep the coffe beans or other products in the bag fresh.
The degassing valve (exhaust valve) types on the market are roughly divided into two kinds, one is the built-in exhaust valve, the other is the external exhaust valve.
The built-in exhaust valve is installed inside the bag, and the installation needs to cooperate with the pressure valve machine to heat the exhaust valve on the bag. The built-in exhaust valve is divided into filter screen type and filter - free. The built-in one-way exhaust valve with a filter can be used in a wide range of applications. It can be used in the packaging of solid and powder items such as coffee beans, pigs, horses and other livestock feed, cat and dog food, flour, coffee powder, ready-mixed baking powder and so on. The built-in one-way exhaust valve without filter screen has a relatively small application range, suitable for coffee beans, cat food dog food and other granular items.
The external type exhaust valve (degassing valve) is generally a patch type exhaust valve, just poke a small hole in the coffee packaging bag surface, and then directly paste the patch type exhaust valve to the small hole. The use of a patch exhaust valve simplifies the packaging process by reducing the number of packaging steps normally required when using a conventional exhaust valve. Convenient and efficient, stick firmly, the same effect as the built-in exhaust valve. External exhaust valve can be used in soft food packaging, composite bags, film or container anytime and anywhere. People can choose the most suitable exhaust valve according to their own needs.
