As the core carrier of high-end luxury food ingredients, high end caviar metal packaging directly determines the storage quality, transportation safety and terminal appearance of caviar. Compared with ordinary food packaging, high-end caviar metal packaging has extremely high requirements for air tightness, stability and appearance delicacy. Slight losses in the whole process of production, warehousing and cold chain transportation will directly cause product depreciation, ingredient scrapping and brand loss, which is the core difficulty in the supply chain management of high-end caviar.

　　The losses of high end caviar metal packaging are mainly divided into three types: process loss, physical loss and performance loss. Process loss is concentrated in the production and processing links. The precision requirements for precision stamping, coating spraying, sealing and pressing of metal cans are strict. Defects such as coating scratches, corner deformation and loose sealing are prone to occur, and slight process deviations will lead to packaging scrapping, which is the main source of finished product loss. At the same time, the food-grade coating material of high-end metal packaging is fragile, and manual operation errors and equipment vibration during processing will aggravate the output of defective products and increase the production loss rate.

　　Physical loss runs through the whole process of warehousing and cold chain logistics. Caviar is stored and transported at low temperature throughout the whole process. Temperature and humidity fluctuations will cause slight thermal expansion and contraction of metal packaging, and long-term stacking pressure is prone to cause tank depression and cover misalignment. In addition, high-end metal packaging has no redundant buffer tolerance. Transportation jolts and handling bumps will cause appearance damage and sealing structure failure, which will not only lose the packaging itself, but also lead to moisture and oxidation deterioration of caviar, causing associated ingredient losses. According to industry data, the loss of high-end ingredients caused by physical damage to packaging accounts for more than 35%.

　　Performance loss is the invisible core loss. During long-term storage, the aging of sealing rings, oxidation of coatings and attenuation of air tightness of metal packaging will gradually lose the fresh-keeping and protective performance. Although there is no obvious damage, it will lead to the loss of caviar flavor and shortened shelf life, resulting in implicit economic losses. In view of the above loss problems, it is necessary to reduce the whole-process losses in an all-round way by optimizing precision production processes, installing buffer protection structures, building intelligent cold chain monitoring systems, and adopting nano-protective coatings, so as to balance high-end texture and practical protection, and achieve dual improvement of quality and efficiency.
