The core requirements for international air cargo packaging are sturdiness, adaptability, and compliance. To avoid damage, it is necessary to control multiple aspects such as packaging ion, protective filling, and fixing reinforcement.
1、 Core requirements for international air freight packaging
1. Basic packaging standards
Priority should be given to corrugated cardboard boxes, wooden pallets/boxes for outer packaging, which must meet the air freight load-bearing rating (corrugated cardboard boxes are recommended to have 5 layers or more).
The packaging should be intact, undamaged, and free from moisture. High strength tape should be used for sealing (avoiding ordinary transparent adhesive), and the joints should be reinforced.
Wooden boxes need to undergo fumigation treatment (with IPPC logo) to prevent the spread of pests and diseases. Some countries may directly detain goods from non fumigated wooden boxes.
2. Requirements for Goods Adaptation
Weight and packaging matching: It is recommended that the weight of a single box should not exceed 30kg. Overweight goods should be packed in thicker packaging or pallets to avoid deformation during transportation.
Dimensional compliance: It must comply with the airline's cargo hold restrictions. Overlong and wide cargo must be declared in advance and secured with specialized packaging.
Special requirements for special goods: Fragile goods need to be packed in shock resistant packaging, liquids need to be sealed and leak proof (independent packaging+anti-seepage layer), and dangerous goods need to be packed in UN certified packaging and labeled accordingly.
3. Compliance requirements
The packaging should clearly indicate the recipient and sender information, as well as the weight and size labels of the goods.
Do not use packaging that is damaged, contaminated, or has old labels to avoid confusion or damage during sorting.
2、 Key measures to avoid damage to goods
1. Internal protection: filling and buffering
Fragile items (glass, electronic devices) need to be wrapped in cushioning materials such as bubble wrap and pearl cotton, and each item should be individually packaged before being packed together.
The space in the box shall be filled with foam blocks and inflatable bags to avoid shaking and collision of goods during transportation. The filling rate is recommended to be more than 90%.
Valuable or precision goods can be added with shock proof foam boxes, and then covered with cartons for double protection.
2. External reinforcement: impact resistance and deformation prevention
The outer part of the cardboard box is reinforced with cross wrapping straps, and corner protection strips are added at the edges to prevent deformation during transportation.
Heavy or irregular goods (such as mechanical parts) need to be fixed on wooden pallets and tightened with bandages or ropes to avoid displacement.
When stacking goods, attention should be paid to the load-bearing capacity of the bottom packaging, and the weight of the upper goods should not exceed the load-bearing limit of the bottom packaging. If necessary, partitions should be used to separate them.
3. Detail control: reduce human and transportation risks
Warning signs such as "Fragile", "Upward", and "Handle with Care" are marked on the outside of the packaging to remind sorting and handling personnel.
Avoid direct contact between the goods and the inner wall of the packaging. Sharp objects (such as metal parts) should be wrapped with soft materials to prevent puncturing the packaging.
Choose legitimate freight forwarders and airlines to ensure standardized transportation and reduce the probability of violent sorting.
3、 Extra attention should be paid to the packaging of special goods
Liquid goods: After sealing the bottle mouth, put it in an anti-seepage bag and place it upright. Fill the box with absorbent materials (such as tissues and desiccants) to prevent leakage and pollution.
Powdered goods: Double layered packaging with sealed bags and cardboard boxes on the outer layer to prevent moisture or leakage.
Large equipment: detachable components, packaged separately, key parts protected with shields, and fixed as a whole on pallets or shelves.
