valve
The main function of the one-way vent valve is to prevent water vapor and oxygen in the air from entering the bag, and effectively preserve its contents. In addition, it can discharge gases and carbon dioxide in the bag, reduce the shock wave generated by the air remaining in the bag, and avoid the package to break. It is often used in coffee packaging. Squeeze the packaging bag vigorously, and the gas mixed with coffee flavor will be discharged from the small hole of the vent valve. This way you can choose different varieties of coffee beans.
Tin-tie
This sealing iron band is not only difficult to deform, but also easy to close. It is often used with gusseted back seal bags and flat bottom bags. A bag of freshly unpacked products gradually fades in flavor over time. As long as it is tightly sealed with a sealing iron band, the contents can be preserved for a longer time. The most commonly used colors are kraft paper, white, black, brown, etc.
