Will Disposable Packaging Boxes Leak If They Have Small Air Holes?

Will not leak. The small air holes are designed to make the air pressure in the box smaller than the outside air pressure. When the lid is placed on the box, the air in the box is compressed and the air pressure decreases. At this time, the small air holes play a key role. They allow outside air to enter the box and keep the air pressure inside the box at a low level, allowing the lid to fit more tightly to the box to prevent air leakage.
