Compared with other paper-based packaging materials, wet-pressed paper trays are not very breathable, but they are not completely non-breathable either. Due to their structure of multi-layer wet-pressed boards and conductive films, the internal space of wet-pressed paper trays is relatively compact. Moreover, they may be wrapped in sealed bags during transportation, which further affects their breathability.

Generally speaking, while wet-pressed paper trays protect packaged items, attention should also be paid to their breathability to ensure the quality and safety of the packaged items. If the packaged goods require a certain level of breathability, you can either choose paper-based packaging materials with good breathability, or add materials with excellent breathability (such as sponges or foam) inside the wet-pressed paper trays.
