June 12, 2019 - Unlike land transportation, sea transportation carries significantly higher risks than inland transportation. Improper packaging of goods for sea export can easily lead to consequences such as moisture, damage, and leakage of the goods, all of which will result in direct economic losses. To avoid these losses, there must be requirements for sea transportation packaging. The packaging of goods should be sturdy and intact, capable of preventing package breakage, leakage, and loss of contents during transportation; preventing damage or deterioration of the goods caused by stacking, friction, shock, or changes in air pressure and temperature; and preventing harm to operators or contamination of aircraft, sea containers, ground equipment, and other items.

        In addition to being suitable for the nature, state, and weight of the goods, the packaging should also facilitate handling, loading, unloading, and stacking; the outer surface of the packaging should not have protruding nails, hooks, spikes, etc.; the packaging should be clean, dry, and free of odor and oil stains. The cushioning materials inside the packaging, such as sawdust and paper scraps, should not leak out. Except for goods packed in paper bags, all consigned goods should be bundled with packaging tape. It is strictly prohibited to use straw bags for packaging or straw ropes for bundling goods. The packaging tape used for bundling goods should be able to bear the full weight of the goods and ensure that it will not break when lifting the goods.

        If the packaging of the goods does not meet the relevant regulations mentioned above, the shipper should be required to improve or repackage the goods before acceptance for transportation. Items that are heavy, valuable, or fragile, such as electrical appliances, pianos, ceramics, handicrafts, and antique furniture, should be packed in wooden boxes with padding to prevent damage from compression. For ordinary dismountable furniture, it is recommended to use five-layer cardboard with white film for packaging. Items that are light or regular, such as daily necessities, books, and clothing, should be packed in cardboard boxes and uniformly palletized. Palletizing can effectively prevent damage and loss of goods, facilitate cargo handling and loading by shipping companies, and reduce a lot of labor costs in the overseas segment.

If there are over-length or over-sized packages, the accurate length, width, height, and weight of each individual package must be provided when booking the shipping space. For liquid goods, 5-10% of the container's interior space must be reserved, and the lid must be sealed tightly; no leakage is allowed. For liquids stored in glass containers, the capacity of each container should not exceed 500 milliliters. It is advisable for the gross weight of each individual cargo item not to exceed 25 kilograms. The interior of the container should be padded and filled with absorbent materials to prevent shaking or liquid leakage.

        Powdery goods. For those packed in bags, the outermost layer should be a plastic-coated textile bag to ensure that the powder does not leak out, and the gross weight of each piece of goods should not exceed 50 kilograms; for those packed in hard paper drums, wooden drums, or plywood drums, it is required that the drums are unbroken, the seams are tight, the lid is sealed, and the hoop is strong and sturdy; for those packed in glass, the weight of the contents in each bottle should not exceed 1 kilogram. For those packed in iron or wooden materials as the outer packaging, the box should be filled with cushioning materials. The gross weight of each piece of goods should preferably not exceed 25 kilograms. Precise, fragile, and fragile goods.

        The gross weight of a single piece of cargo should not exceed 25 kilograms, and the following packaging methods can be adopted: multi-layer packaging: that is, cargo, cushioning material, inner packaging, cushioning material, and transport packaging. Suspended packaging: that is, using several springs or ropes to suspend the cargo in the middle of the box from all directions. Anti-inversion packaging: that is, packaging with a large base, a carrying handle ring, or a ridge-style lid; such packaging must be used for glass plates and windshields that are not suitable for being placed flat. Packaging for glassware: sufficient thickness of foam plastic and other cushioning materials should be used to wrap tightly, and a sturdy corrugated cardboard box or wooden box should be added, ensuring that the items inside the box do not shake.

        Goods that are not packaged or not sensitive to impact and pressure, such as tires, can be left unpackaged. However, goods that are difficult to count, have irregular shapes, resemble transportation equipment in appearance, or are prone to damaging aircraft should be wrapped with ropes or linen cloth, or additionally packaged. For large goods, those with a large volume or weight should have sleepers or bottom supports at the bottom to facilitate forklift operation.

        Due to the long duration and high humidity of sea transportation, as well as the airtight and unventilated nature of sea freight packaging boxes, clothing is prone to mold growth. However, with extra attention to packaging, this can be avoided. So, what are the main packaging materials and requirements for clothing? Plastic bags. The transparency of plastic bags should be strong, with clear and non-fading printed words and patterns, and they should be aligned vertically with the clothing they contain. The size of the plastic bags must be suitable for the actual items, and the items should be placed flat inside the bags with appropriate sealing tightness, without any signs of glue failure or damage. Paper boxes. Paper boxes should be kept clean, sturdy, and dry inside and out, suitable for long-distance transportation. They should be lined with moisture-proof materials to protect the goods. The bottom and lid of the box should be sealed tightly and securely, with the sealing paper pasted straight and both sides hanging down by 10cm. The size of the inner and outer packaging should be appropriate. The reinforcement bands should be straight and of appropriate tightness, without any signs of detachment. The buckles should be secure. Wooden boxes. The boards should be clean, and wooden boxes that are worm-eaten, moldy, damp, or decayed are not allowed. They should be suitable for long-distance transportation. Nail tips should not be exposed inside the box. The box should be lined with moisture-proof materials to protect the goods. The reinforcement bands should be straight and of appropriate tightness, without any signs of detachment, and the buckles should be secure.
