Description

Technical Field

[0001] The utility model relates to a packaging structure for electroplated tinned steel coils used for export bulk carriers and centralized box transportation, belonging to the technical field of long-distance transportation of steel coils. Background Art

[0002] As an environmentally friendly and safe packaging material, tin-plated steel coils are widely used in food cans, beverage cans, aerosol cans, chemical barrels, and various other packaging cans. When tin-plated steel coils are exported abroad, due to the long transportation distances, they must be transported by bulk carrier or container. This process is also relatively lengthy. The transportation process includes: transportation from the factory to a domestic port, unloading and hoisting at the port, storage at the port, hoisting onto a bulk carrier or container at the port, and upon arrival at the destination port, further hoisting and unloading, storage at the destination port, and finally transportation to the destination company. The entire transportation process requires multiple hoists and transshipments, which can easily damage the outer packaging of the tin-plated steel coils. Furthermore, due to the extreme temperature fluctuations during transportation (possibly passing through the equator and high-altitude cold regions), a large amount of condensation will adhere to the outside of the tin-plated steel coil packaging inside the container or bulk carrier. The outer packaging of tin-plated steel coils in existing technology mostly adopts bottom trays, plastic sheets and binding tapes, which can easily cause damage to the packaging and fail to effectively protect the tin-plated steel coils. The tin-plated steel coils are often wetted by rain or condensation water enters the packaging, causing water ingress and rust of the tin-plated steel coils, thus losing their original value.
