Seaworthy wooden packaging refers to the use of wooden materials to create packaging solutions that are suitable for transportation and storage of goods via sea routes. The primary purpose of seaworthy wooden packaging is to protect the goods from potential damage during long sea journeys.

Key characteristics of seaworthy wooden packaging include:

1. Durability: The wooden materials used for packaging must be strong and sturdy to withstand the rigors of sea transportation. 

2. Moisture resistance: The packaging must be designed to protect the goods from moisture and water. This may involve treating the wood with protective coatings or using moisture-resistant adhesives during assembly.

3. Compliance with international regulations: Seaworthy packaging must meet international regulations and standards set by organizations.

4. Proper sealing : All joints and openings in the wooden packaging should be properly sealed to prevent water from seeping in during transportation.
