Specialized tracks are used in the transport of cultural properties, and each process is carefully transported by a specialized technician, so basically the vibration received during transport is compared with case of commercial products, it is much smaller. However, even though the level of vibration in the environment is low, the material itself is extremely fragile, so careful attention must be paid to the cultural property. It is necessary to understand the vibration characteristics of the packing material in an environment where the input acceleration is low. Vibration test for understanding the vibration characteristics of the polyethylene foam material used frequently in the packaging of cultural properties was carried out. As a result, it was found that the natural frequency of the cushioning material changes as the input acceleration changes. In addition, when the input acceleration decreases, the transmissibility at the natural frequency of the cushioning material sharply decreases accordingly. It is important to understand the vibration characteristics of commonly used packaging materials in detail within the range of the cultural property transport environment level.

Corrugated box packages stored at wearhouses near seasides, sometimes buckled or collapsed. When corrugated boxes are stored near seasides, effect of receiving salty breeze is assumed. Since sea breeze contains salt and its salinity attracts water, there is concern that the compression strength of corrugated box may be reduced, if salt adheres to the corrugated box. Therefore, the relationship between salt and corrugated fiberboard and corrugated box were investigated in table tests and considered influence by moisture content and compression strength aspects.Furthermore, the salt adhered on corrugated boxes left outdoors near seaside for about a month was measured, and considered the influence on corrugated box by sea breeze. In conclusion, it was confirmed that salt content in sea breeze had little effect on the moisture content of corrugated box.
