In its most common application, the valve is used to release, from a container, gas emitted by a product (such as roasted coffee) while preventing air from entering the container and coming in contact with the product itself.
The aroma of coffee can be smelled through the exhaust valve, and at the same time, the coffee beans are prevented from oxidizing and the aroma is quickly emitted, ensuring the quality of the coffee beans.
Besides,It can also be used for food bags, pet food bags, etc.

They didn’t work for me
I’d hoped to be able to use them on plastic bags to make them vacuum bags, but you need some kind of machine to adhere them. Was worth a try in my quest to stop wasting food- but didn’t;t work for my purpose.PS I don’t know which side is supposed to go out and which is in. There are no instructions or diagrams.
