Export ocean freight is a high-risk phase for soft packaging failures. This article breaks down the formation mechanism of condensation (container rain) inside containers, the damage caused by diurnal temperature and humidity cycles to laminated films and seals, and the stress logic of stacking compression. It provides a comprehensive protection plan covering desiccant configuration, moisture-proof barrier combinations, and pre-shipment verification. Combined with stacking and temperature-humidity cycling test methods, it helps factories and brand owners truly reduce ocean freight damage rates.
