Perfect insect deterrent with the air release system
Not only can air be released, it is also possible to adjust the airflow. It is an innovative air release system that doubles as an insect deterrent.
Air release system
By closing the top of the side gusset package with a fiber vent, air can be released from the package. Since there is not actually an open hole, insects cannot enter the package.
The air release part of the fiber vent can also be adjusted. If the air flow is too high, then it can be adjusted to fix the problem.
