WHY CHOOSE BN PACKAGING?
· We are a SGS certified factory, the price is competitive.
· The factory is dust-free system, make sure the bags can touch the food and our material areSGS/FDA food grade standard.
· We use the Swiss WIPF valve, this valve allows excess gas (which coffee still produces for some time after roasting) to escape, while at the same time oxygen cannot enter the coffee pouch. In this way the flavor and aroma of the coffee is excellently preserved.
· 1 year warranty for all the pouches and 3 years for valve.
Advantage of wipf degassing valve:
1. Higher barrier protection against oxygen and moisture to guarantee the freshness of coffee and extend shelf life.
2. It allows excess gas effectively (which coffee still produces for some time after roasting) to escape to avoid the bags swell.
