我们的密封技术如何防止干冰融化？

绝缘泡沫只是战斗的一半；另一半是密封。如果温暖的空气进入箱体，干冰将迅速升华。为防止这种情况发生，我们的 cooler boxes feature a wide, high-quality EVA sealing strip recessed into the lid. When the lid is closed, this strip is compressed to create an airtight barrier.

This seal is maintained by our robust locking systems. Whether it’s the rubber T-latches on our smaller models or the recessed twist locks on our larger units, they apply constant downward pressure. This design minimizes air exchange (convection) and ensures that the internal temperature remains stable, drastically extending the life of your dry ice or frozen goods.
