Empty Gold Caviar Tin Box, with super load-bearing performance as the core competitiveness, based on the high-end positioning, bulk storage, transportation adaptability and quality stability needs of empty gold caviar tin boxes, adheres to the production concept of "strong load-bearing, superior quality and high grade". Relying on high-strength base material selection, precision structural design and refined processing technology, it perfectly integrates load-bearing performance with high-end gold texture, creating empty gold caviar tin boxes with super load-bearing, sturdiness, excellent sealing and outstanding appearance. Suitable for diverse high-end scenarios such as caviar packaging OEM, high-end gift box matching, bulk group purchase, export trade, high-end supermarket display and private collection, covering various needs such as bulk purchase by caviar manufacturers, high-end food packaging supporting, luxury brand customization, high-end cultural and creative supporting, and cross-border export supply. With excellent load-bearing performance and high-end gold texture, it breaks the drawbacks of traditional caviar tin boxes such as "weak load-bearing, easy deformation and cheap texture", and becomes a load-bearing benchmark in the field of empty gold caviar tin boxes, helping customers enhance the high-end style of products, reduce transportation and storage losses, and improve market competitiveness, achieving a triple win of load-bearing, quality and appearance. It not only meets the aesthetic needs of high-end packaging, but also adapts to the practical needs of bulk storage and long-distance transportation, highlighting the professional quality of high-end food packaging.

　　The core foundation of super load-bearing is the dual support of high-strength base materials and scientific structural design. We abandon the drawbacks of thin base materials and loose structure of traditional tin boxes, and select high-purity food-grade thickened tinplate as the core raw material. The thickness of the base material is upgraded to 0.35mm-0.5mm, which is more than 40% higher than that of ordinary caviar tin boxes. The tensile strength of the base material itself can reach 320MPa-380MPa, and the compressive strength can reach 280MPa-320MPa, laying a solid foundation for super load-bearing performance. At the same time, according to the high-end positioning and load-bearing needs of empty gold caviar tin boxes, a precision structural optimization design is adopted. The box body adopts an integrated forming process of reinforcing ribs, the box bottom adopts a double-layer reinforcement structure, the connection between the box cover and the box body is equipped with reinforced buckles, and the corners are treated with rounded corner reinforcement, comprehensively improving the overall load-bearing capacity and structural stability of the tin box. It ensures that the tin box can stably bear 8-12kg, far exceeding the load-bearing standard of 3-5kg of ordinary caviar tin boxes, and can easily cope with extrusion and collision during bulk stacking storage and long-distance transportation, eliminating problems such as box body depression, deformation and damage caused by insufficient load-bearing, greatly reducing transportation and storage losses, and ensuring the good appearance of each batch of products.

　　Refined processing technology is the key to enhancing load-bearing performance and highlighting high-end texture. We have built a full-process refined processing system, equipped with a full set of high-end precision processing equipment, including precision CNC punch presses, high-frequency seamless welding machines, fine grinding machines, gold vacuum coating equipment and other professional equipment, deeply integrating processing technology with load-bearing needs, and pursuing excellence in every process to ensure the structural stability and load-bearing uniformity of the tin box. In the base material processing link, precision cutting and stamping processes are adopted to accurately control the size and thickness error of the base material, with an error controlled within ±0.01mm, ensuring that each base material has uniform thickness and texture, avoiding uneven load-bearing and local easy damage caused by uneven base material thickness; In the box body forming link, an integrated stamping reinforcing rib process is adopted, and the reinforcing ribs are integrally formed with the box body without additional splicing, which not only improves the overall load-bearing capacity of the box body, but also avoids the hidden danger of loosening and breaking at the splicing position. The spacing of the reinforcing ribs is accurately controlled at 2.5cm-3cm, which can evenly disperse the load-bearing pressure, making the tin box bear force evenly during load-bearing and not easy to deform.

　　The double-layer reinforcement of the box bottom and seamless welding technology further enhance the load-bearing performance and structural stability, which are the core guarantees for the super load-bearing of the empty gold caviar tin box. The box bottom is formed by superimposing double-layer thickened tinplate, and the double-layer base materials are closely attached, achieving seamless connection through 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 95% of the strength of the base material itself, completely eliminating problems such as loosening, falling off and damage of the box bottom, greatly improving the load-bearing capacity of the box bottom, which can independently bear 6-8kg. It ensures that when the tin boxes are stacked and stored, the bottom can stably support the weight of the upper layer, avoiding overall collapse caused by insufficient load-bearing of the box bottom. At the connection between the box cover and the box body, a combination of reinforced buckle design and precision welding is adopted. The buckles are tightly engaged and not easy to loosen, and the connection part is firmly welded, which not only ensures the sealing performance of the tin box, but also enhances the load-bearing capacity of the connection part, avoiding fracture and deformation of the connection part during opening and closing. At the same time, it ensures that when the tin boxes are stacked, the upper and lower boxes are closely connected, improving the overall stacking load-bearing stability, which can realize 5-8 layers of bulk stacking, and the total stacking load-bearing can reach 40-60kg, adapting to the needs of bulk warehouse storage.

　　The gold surface treatment process and strict load-bearing testing balance high-end appearance and load-bearing quality, highlighting the high-end positioning of the empty gold caviar tin box. In the surface treatment link, high-end vacuum gold plating technology is adopted. The gold plating layer is uniform and full, bright in color, free of color difference, scratches and falling off, corrosion-resistant and oxidation-resistant, which not only highlights the high-end and luxurious style, but also enhances the surface hardness of the tin box, improves the surface wear resistance and scratch resistance, and does not affect the load-bearing performance of the tin box; Some high-end styles adopt matte gold treatment, with a warm and delicate texture, adapting to more high-end scenarios. In the load-bearing testing link, a full-process load-bearing quality inspection system is established, and professional load-bearing testing equipment is used to sample test each batch of products, focusing on testing the box body load-bearing, box bottom load-bearing, stacking load-bearing and the load-bearing of the connection part, ensuring that the load-bearing performance of each empty gold caviar tin box meets the standard, the load-bearing error is controlled within ±0.5kg, and the deformation of the tin box under load-bearing is detected at the same time, with the deformation ≤0.3mm, eliminating obvious deformation, damage and other problems during load-bearing. In addition, we can flexibly adjust the tin box thickness and structural design according to customer needs, adapt to different load-bearing needs, support personalized services such as size customization, logo engraving and pattern customization, balancing load-bearing performance, high-end appearance and personalized needs.
