Wojin Plastic Product Factory was established in 2012, we are a professional manufacturer of coffee valve (one way degassing valve) and the semi-automatic valve applicator in China. Our own brand is named as WOJIN. We are in the leading position on the introduction of fully automatic production lines, which allow us to reach a high product qualification rate as 99.9997%. Our goal is to serve the customer with better products and services.
Wojin coffee valve is mainly applying to food packaging including coffee bag and feed fermentation bag. Additionally, we produce semi-automatic hot pressure sealing valve applicator and supply a big variety of packaging bags. The raw material we use HDPE from the USA.
How to Distinguish the Quality of One Way Degassing Valve
1.The easy way to test it is by pumping the air from the bags with one way degassing valve after sealing, and then see if the bag will expand or not.
2.Test the freshness of coffee
Making a cup at different times, one month, two months, or even three months longer time using the valve, write down the test result and make the comparison, Compare the foam volume and the acidity of the coffee, if there still is a lot of foam and the coffee taste less sour, it is said that the coffee is kept well. Otherwise,,the one way degassing valve is not good and cant keep the freshness of coffee effectively.
3. Check the fermented feed
The one way degassing valve placed in the packaging bag aims to help vent the air that is produced by the feed to keep the high quality of fermented feed for a longer time. If there is gas trapped in the packaging bag, or the fermented feed is moldy, its no doubt that the one way degassing valve is inferior.
