Air fresh fruit and vegetable packaging box

In order to keep fruits and vegetables fresh during the airlift process, a U.S. company invented a new method to reduce oxygen and increase nitrogen content in packaging boxes to keep fruits and vegetables fresh. This method uses a new type of air conditioning box with air-conditioning performance. This package has a special film, which can absorb oxygen molecules and allow nitrogen to pass through. After entering the package through the film in the air, the content of nitrogen in the box can be as high as 98% or more, so that the respiration of fruits and vegetables can be slowed down and the purpose of keeping freshness for a longer period of time can be achieved.
