　　1. Premium Food-Grade Material Selection, Perfect for Caviar Storage

　　Caviar is a high-value and easily oxidized premium ingredient with strict requirements for storage environment. The safety, tightness and stability of packaging materials directly determine the fresh-keeping cycle and quality of ingredients. All our custom caviar tin boxes are made of imported first-class food-grade tinplate, which is lead-free, non-toxic, environmentally friendly and odorless. It fully complies with EU food contact standards, FDA food testing certification and domestic GB4806 food safety specifications, can be in direct contact with high-end food, eliminating problems such as heavy metal precipitation and odor pollution, and adapting to the strict quality inspection requirements of import and export cross-border trade.

　　Compared with plastic boxes, glass boxes and ordinary paper boxes, custom caviar tin boxes made of tinplate have irreplaceable core advantages. The material has excellent barrier properties, which can effectively isolate air, water vapor, ultraviolet rays and external pollution, fundamentally preventing caviar from oxidative deterioration, moisture agglomeration and flavor loss. The metal material features high hardness, extrusion resistance and drop resistance, which can effectively protect finished caviar products during cold chain transportation, storage and display, avoiding box deformation and ingredient damage. Meanwhile, tinplate is low-temperature resistant and aging-resistant, which can be adapted to long-term refrigerator refrigeration and low-temperature cold chain storage and transportation. It will not deform, crack or deteriorate due to temperature differences, maximizing the original flavor and fresh taste of caviar.

　　We support customized material thickness differentiation. According to customers' product specifications, transportation and storage scenarios and positioning needs, we select food-grade tinplate with different thicknesses from 0.20mm to 0.35mm. The thin and lightweight version is suitable for small-sized portable packaging and supermarket retail display; the thickened and reinforced version is adapted to large-capacity high-end gift box packaging, long-distance cross-border transportation and batch storage and turnover, balancing portability and structural stability to fully meet the customized needs of different customers.

　　2. Precision Structure Customization, Professional Fresh-Keeping Sealing Design

　　Sealing and fresh-keeping are the core indicators of caviar packaging and the key advantages of our custom caviar tin box customization service. We abandon the simple opening and closing structure of ordinary tin boxes, adopt professional food-grade sealing structure design, optimize the cover engagement and fitting technology in a targeted manner, and create a high-sealing storage space. The product is equipped with precision inner curling edge bonding technology and food-grade silicone sealing gasket. The box cover and body fit seamlessly with tight and stable sealing, which can lock the unique flavor of caviar and extend the fresh-keeping cycle of ingredients. It can be opened and closed repeatedly after opening, facilitating separate storage and consumption.

　　The structure style supports full-dimensional non-standard customization without fixed specification restrictions. Main customized styles include round caviar tin boxes, square sealed tin boxes, oval luxury gift boxes, special-shaped creative packaging boxes, double-layer thickened fresh-keeping tin boxes, and separate storage boxes with inner trays. According to customers' caviar products of different capacities such as 10g, 20g, 30g, 50g, 100g and 250g, we can customize the inner diameter, depth and overall size accurately to achieve a perfect fit between the box and the product, avoiding ingredient loss caused by shaking during transportation.

　　Meanwhile, we support diversified functional structure upgrades. We can customize flip-top, heaven and earth cover, screw cap and buckle lock opening and closing structures; install anti-theft buckles and one-time anti-counterfeiting seals to prevent product replacement and counterfeiting and protect the genuine attributes of high-end products; equip with food-grade sponge inner trays, EVA shockproof liners and separate clamping grooves to fix products and prevent shock and scratch; reserve exclusive label positions and traceability code pasting positions to adapt to brand traceability and product information display needs, realizing dual upgrading of practicality and professionalism.

　　3. High-End Appearance Craft Customization, Create Brand Luxury Texture

　　4. Full-Process Quality Control System, Ensure Stable Batch Quality

　　High-end food packaging has extremely high requirements for quality stability, safety and fineness. We have established a full-link standardized quality control system from raw material warehousing to finished product delivery, strictly controlling every production process to guarantee the quality of each batch of custom caviar tin boxes. Before raw material warehousing, material testing, food safety testing and thickness screening are carried out one by one to eliminate unqualified raw materials from production. During production, the precision of cutting, forming, bonding, printing and sealing processes is monitored in real time to strictly control process problems such as dimensional errors, color difference, burrs and poor sealing.

　　Free sampling is provided before mass production. We accurately confirm the size, structure, color, process and sealing effect, and start mass production only after the customer confirms the sample is correct, avoiding batch defects and customization deviations from the source. Before delivery, finished products undergo full inspection, including appearance defect detection, dimensional accuracy verification, sealing performance test, low-temperature weather resistance test and food safety re-inspection, ensuring that each product has tight sealing, exquisite appearance, accurate size and compliant safety, fully meeting the strict standards of high-end food export, supermarket shelf display and gift box sales.
