Reusable Metal Caviar Tin, with full-process low loss as the core competitiveness, based on the core needs of reusability, high-end packaging, mass production and long-term use, adheres to the production concept of "low-loss exquisite craftsmanship, circular durability and green efficiency". Relying on high-strength metal base materials, precision processing technology, scientific structural design and full-process loss control system, it perfectly integrates low-loss characteristics, reusability and high-end texture, creating high-end metal caviar tin boxes with low production loss, low transportation loss, low use loss and recyclability. Suitable for diverse high-end scenarios such as caviar packaging OEM, high-end gift box matching, bulk group purchase, export trade, private collection and high-end catering supporting, covering various needs such as bulk purchase by caviar manufacturers, high-end food packaging supporting, luxury brand customization, cross-border export supply and high-end catering store supporting. With the advantages of full-process low loss and reusability, it breaks the drawbacks of traditional metal caviar tin boxes such as "high production loss, easy damage during transportation and easy aging during use", and becomes a low-loss benchmark in the field of reusable metal caviar tin boxes, helping customers reduce production costs, reduce transportation losses, improve product reuse rate, and achieve a triple win of loss, quality and environmental protection. It not only meets the aesthetic and practical needs of high-end packaging, but also practices the concept of green circulation, balancing economy and environmental protection.

　　The core embodiment of low loss is the loss control in the whole process of production, transportation and use. We abandon the drawbacks of extensive production, loose structure and thin materials of traditional metal tin boxes, and build a full-process low-loss control system from raw material selection to finished product delivery, from transportation and storage to reuse, strictly controlling the loss rate within 0.3%, far exceeding the industry average loss standard of 1.5%, and comprehensively achieving the production and use goal of "cost reduction, consumption reduction, circulation and efficiency". Low loss in the production link is the foundation for controlling overall costs and improving production capacity. We select high-purity food-grade 304 stainless steel and thickened tinplate as the core raw materials, with a base material utilization rate of more than 99.7%, which is more than 15% higher than that of traditional metal tin boxes. Through precision cutting and integral forming processes, we reduce the waste of edges and corners during raw material cutting and eliminate raw material loss; At the same time, we are equipped with a full set of high-end precision processing equipment, optimize the processing process, reduce the scrap rate during processing, set strict loss standards for each process, monitor processing loss in real time, and adjust process parameters in a timely manner to ensure that production loss is minimized. It not only ensures mass production efficiency, but also greatly reduces raw material and processing costs, realizing efficient and low-loss production.

　　Low loss in the production link is inseparable from the dual empowerment of precision processing technology and intelligent control. We adopt refined processing technologies such as precision CNC cutting, integral stamping forming and high-frequency seamless welding, accurately control each processing parameter, control the cutting error within ±0.01mm, and accurately adjust the stamping pressure and temperature, avoiding product scrapping caused by processing deviations. The processing scrap rate is controlled below 0.2%, far lower than the industry average of 1.2%. According to the core demand of reusability, we optimize the welding process and adopt high-frequency seamless welding technology. The welds are smooth and flat, free of slag inclusion and air holes, and the welding strength can reach more than 98% of the strength of the base material itself, eliminating problems such as missing welding and insufficient welding during the welding process, avoiding product scrapping caused by welding defects, and improving the structural stability of the product, laying a foundation for subsequent reuse and reducing use loss. In addition, we introduce an intelligent production control system to monitor the entire production process in real time, accurately count raw material loss and processing loss, and timely detect and solve loss hidden dangers, ensuring that the low loss in the production link is stable and controllable. The daily output can reach more than 500,000 pieces, balancing efficient mass production and low loss needs.

　　Low loss in the transportation and storage links is one of the core advantages of reusable metal caviar tin boxes, and also the key to helping customers reduce costs. According to the transportation and storage needs of metal tin boxes, we optimize the structural design. The box body adopts an integrated forming process of reinforcing ribs, the box bottom adopts a double-layer reinforcement structure, the corners are treated with rounded corner reinforcement, and the connection between the box cover and the box body is equipped with reinforced buckles, comprehensively improving the anti-collision, anti-extrusion and anti-wear capabilities of the tin box. It can bear a stable load of 8-12kg, and the total stacking load can reach 40-60kg, adapting to 5-8 layers of bulk stacking storage, eliminating losses such as box body depression, deformation and damage caused by extrusion, collision and improper stacking during transportation and storage. The transportation loss rate is controlled within 0.1%, far lower than the industry average transportation loss standard of 0.8%. At the same time, we adopt customized protective packaging. Each tin box is equipped with an independent protective cover, and a shockproof and anti-extrusion packaging scheme is adopted for bulk transportation, reducing friction and collision during transportation, further reducing transportation loss, ensuring that each batch of products is in good condition and free of any damage from the production workshop to the customer's hands, and greatly reducing the customer's transportation and rework costs.

　　Low loss and reusability in the use link are the concentrated embodiment of the core value of the product, and also the key to practicing the concept of green circulation. The high-strength metal base material we selected has a tensile strength of 350MPa-400MPa, a compressive strength of 300MPa-350MPa, corrosion resistance, oxidation resistance and wear resistance. The surface is treated with high-end vacuum coating and scratch-proof treatment, which greatly improves the surface hardness, and can effectively resist scratches and wear in daily use, avoiding the decline in appearance and service life caused by surface wear; At the same time, we optimize the connection structure between the box cover and the box body, adopt a reinforced buckle design that can be opened and closed repeatedly, which is smooth to open and close and tightly engaged, and can be opened and closed more than 1000 times without loosening or deformation, eliminating problems such as fracture and deformation of the connection part caused by frequent opening and closing, greatly extending the service life of the product, realizing long-term reuse, and reducing the loss and replacement cost in the use link. In addition, the tin box has excellent sealing performance with a gap ≤0.02mm, which can effectively isolate air, moisture and peculiar smell. There is no need to worry about the decline of sealing performance during reuse, which not only ensures the storage freshness of high-end foods such as caviar, but also avoids product waste caused by poor sealing, further realizing low loss in the use link.
