In cross-border trade of tropical fruits, durian has become an "odor challenge" in transportation due to its strong aroma and high sugar content. If containers for durian transportation lack proper anti-odor transfer design, volatile substances released by durian may penetrate into container materials and even pollute other goods in the same batch, such as tea and coffee beans, resulting in economic losses. Therefore, anti-odor transfer design has become one of the core indicators for evaluating the performance of such containers.

The key to anti-odor transfer for durian transportation containers lies in material selection and structural optimization. Traditional metal containers tend to absorb odor molecules, while new composite materials such as polyethylene or modified polypropylene feature higher surface compactness and can effectively reduce odor penetration. Meanwhile, nanocoatings can be applied to the inner walls of containers to further lower the risk of odor residue through dual effects of physical adsorption and chemical decomposition. In terms of structural design, vents should be equipped with detachable filters, which not only ensure air circulation but also block durian residues and odor particles to avoid circulating pollution inside the ventilation system.

The upgrading of technical methods provides more possibilities for anti-odor transfer. For example, some manufacturers integrate negative pressure systems into durian transportation containers, which continuously suck out indoor air, filter it through activated carbon and discharge it, reducing odor diffusion at the source. In addition, for short-haul transportation or small-batch orders, modular partition design can be adopted to divide the container into independent sealed compartments, so that different goods do not interfere with each other. Even if odor leakage occurs in a single compartment, the whole container will not be affected. These technologies are not isolated; they should be combined comprehensively according to transportation distance, cargo type and cost budget to achieve satisfactory results.

Anti-odor transfer design is not only a technical issue, but also an inevitable choice for the industry to adapt to market demand. With higher consumer requirements for food freshness and purity, as well as growing demand for mixed transportation of multiple categories in cross-border e-commerce, the anti-odor transfer capability of containers for durian transportation will become an important reflection of logistics enterprises’ competitiveness. In the future, with the development of material science and intelligent control technology, anti-odor transfer design will become more refined, building an "odor firewall" for tropical fruit trade.
