As the core protective equipment for long-distance transportation of materials, the shipping vacuum tin derives its reliable performance from precise and strict parameter design. Each performance index is tailored for the transportation scenario, balancing sealing, pressure resistance, stability and convenience. It can effectively resist complex working conditions such as bumps, temperature and humidity changes, and air pressure fluctuations during transportation, protect the safety of materials, and adapt to the long-distance transportation needs of various materials such as chemical raw materials, precision components and high-end food, becoming a safety guarantee in logistics transportation.

　　Core performance parameters meet strict standards: the working vacuum degree of the tank is 0.02-0.1MPa, the vacuum holding time is more than 72 hours, and the leakage rate is ≤0.001Pa·m³/s, which can maintain the vacuum environment in the tank for a long time, effectively isolate air, moisture and impurities, and prevent materials from oxidation, deterioration or damage; the compressive strength is 1.2MPa, and the impact strength is ≥15J/cm², which can resist collisions and bumps during transportation, ensuring the tank body does not deform or break, and is suitable for various transportation methods such as highway, railway and maritime transportation.

　　Size and load-bearing parameters are flexibly adaptable: the tank volume ranges from 0.5-50m³, which can be customized according to transportation needs, with a diameter range of 300-2000mm, a height of 800-5000mm, an empty tank weight of 50-5000kg, and a rated loading weight of 100-10000kg, adapting to the transportation needs of materials of different specifications; the tank body adopts a lightweight design, with its own weight 15% lower than that of ordinary transportation tanks, which not only reduces transportation costs but also improves loading efficiency.

　　Environmental adaptation and safety parameters are fully upgraded: the working temperature range is -30℃ to 120℃, which can adapt to transportation environments in different regions and seasons, without softening at high temperatures or brittle fracture at low temperatures; it is equipped with high-precision vacuum pressure gauges, safety valves, explosion-proof valves and other safety components, which automatically release pressure when the pressure exceeds the standard, eliminating potential safety hazards; the material meets international transportation standards, without precipitation of harmful impurities, adapting to high-standard transportation scenarios such as food and pharmaceuticals, and comprehensively protecting material safety and transportation compliance.
