1. Optimize packaging and cushioning protection
High-strength five-layer corrugated cardboard boxes are used as the outer packaging base to ensure compression and impact resistance. Fragile items and precision instruments should be wrapped with bubble wrap or pearl cotton inside, at least three times, and the seams should be reinforced longitudinally with tape. The gaps inside the box should be filled with honeycomb cardboard or air bags to eliminate space for movement and prevent collisions during transport. For heavy equipment, it is recommended to use wooden pallets with steel straps for securing them, improving overall structural stability.
2. Scientific loading and center of gravity distribution
Cargo inside containers should follow the principle of heavier items at the bottom and lighter items at the top. Large machinery and metal products should be placed at the bottom, while lightweight textiles or paper products should be placed at the top. Irregularly shaped items should have gaps filled with inflatable bags or foam blocks to prevent shifting during transportation. Anti-slip mats should be laid between each layer of cargo, and nylon straps should be used to secure them at a 45-degree angle to ensure overall stacking stability. Avoid "pyramid" stacking to prevent deformation of the bottom of the container due to pressure.
3. Strengthen environmental control and moisture-proof measures.
Condensation can easily form inside containers during sea transport, especially on translatitude routes. A PE moisture-proof film should be laid inside the cardboard box, with 50 grams of silica gel desiccant placed per cubic meter of space, and the container sealed in a non-woven bag to prevent leakage. For sensitive goods such as electronic equipment, food, and textiles, it is recommended to wrap them with waterproof stretch film and place a moisture-proof pallet at the bottom. On high-humidity routes, temperature and humidity monitoring equipment can be installed to monitor changes in the cabin environment in real time.
4. Standardized labeling and operating instructions
All packaging must be clearly labeled with warning signs in both Chinese and English, such as "Fragile," "This Side Up," "Keep Dry," and "Do Not Stack." These signs should be located on the front and top of the box to ensure easy visibility for loading and unloading personnel. Valuable items may be accompanied by additional warnings such as "Decision Instrument, Handle with Care" to enhance the level of attention required. A complete video recording of the packaging and loading process should be taken before packing to document the process and provide evidence in case of potential disputes. Proper visual guidance significantly reduces the risk of damage due to human error.
