Customization as You Wish, Data as Proof — Custom lunch tin box, with "precise data, customized adaptation, safety and practicality" as the core, focuses on diverse scenarios such as home use, office, campus and enterprise customization, breaking the limitation of ordinary lunch boxes that are "vague in data, poor in adaptability and uneven in quality". It defines the quality standard of custom lunch tin boxes with detailed and accurate core data indicators, balancing customization flexibility and performance stability, adapting to different customization needs of individuals, enterprises and institutions. Each custom lunch tin box can match the use needs with precise data, show quality with data, and convey sincerity with customization, becoming a high-quality lunch storage choice that combines practicality, safety and personalization.

　　Strict material data, double compliance with safety and durability. The custom lunch tin box is made of food-grade thickened tinplate, with a thickness accurately controlled between 0.22mm and 0.3mm, an error of ≤±0.02mm, a tensile strength of ≥270MPa and an elongation of ≥11%. It has passed strict detection of metal materials in contact with food, complying with the national food safety standard GB 4806.9-2016 and international certifications such as FDA and CE. The heavy metal content is ≤0.005mg/kg, without peculiar smell or harmful substances, and can directly contact various foods such as rice, vegetables and meat, protecting food safety from the source. The can body is treated with electrostatic spraying + high-temperature curing process, with a coating thickness of 18μm-22μm, adhesion reaching grade 4B, not easy to fall off or scratch, no rust after 48 hours of salt spray test, and no obvious scratches after 500 times of friction test. The service life can reach 3-5 years, far exceeding ordinary plastic lunch boxes, adapting to long-term repeated use scenarios.

　　Size and capacity data, customized to adapt to diverse needs. Full-specification customization is supported, with sizes covering 15cm-25cm in length, 10cm-18cm in width and 6cm-12cm in height, with an error controlled within ±0.1cm. The length, width and height can be flexibly adjusted according to needs, adapting to the use needs of different groups and scenarios. The capacity range is 300ml-1200ml, accurately matching the needs of single-person meals, two-person meals and multi-person sharing meals: 300ml-500ml is suitable for children's meals and light meals, 500ml-800ml is suitable for adults' daily lunch, and 800ml-1200ml is suitable for family sharing, outdoor picnics and other scenarios. The partition design of the box body can be customized, and the proportion of partition capacity can be flexibly adjusted. For example, the double partition can be set with a 6:4 or 5:5 capacity ratio, and the triple partition can be set with a 4:3:3 capacity ratio, meeting the needs of classified storage of ingredients, avoiding taste mixing, and balancing practicality and convenience.

　　Outstanding performance data, adapting to daily use scenarios. The sealing performance meets the standard. The can mouth is equipped with a food-grade silicone sealing ring, with a sealing ring thickness of 3mm-5mm, a sealing pressure of ≥0.3MPa and an air leakage rate of ≤0.008%, which can effectively prevent moisture, leakage and taste mixing. Even if it contains liquid food such as soup and sauce, there will be no leakage, adapting to carrying scenarios such as commuting and outdoor activities. The thermal insulation performance is excellent, which can maintain the food temperature for 4-6 hours at room temperature, and can be extended to 8-10 hours with an insulation bag, keeping warm in winter and fresh in summer, meeting the use needs of different seasons. The compression resistance is outstanding, with a compressive strength of ≥280N, which can bear 5 layers of stacking without deformation, facilitating storage and carrying. At the same time, the temperature resistance range is -20℃ to 120℃, which can be directly put into the refrigerator for cold storage and microwave heating (the metal model needs to remove the sealing cover), adapting to various use scenarios and improving the convenience of use.

　　Customization and safety data, balancing personality and compliance. Customization parameters can be accurately controlled, with a printing precision of ≥300dpi. Logos, patterns, texts and other contents can be customized, with printing adhesion reaching grade 3B, no fading or falling off after long-term use. The minimum order quantity for customization can be as low as 100 pieces, supporting small-batch personalized customization, meeting diverse needs such as enterprise employee benefits, campus customization and gift customization. The safety test data is complete. Each batch of products has passed multiple tests such as physical and chemical testing, sealing testing and heavy metal testing, with a qualification rate of 99.9%, no formaldehyde and no harmful volatile substances, complying with national food safety standards, and suitable for all groups such as children, the elderly and office workers. At the same time, the product degradation rate is ≥90%, which can be naturally degraded after disposal, green and environmentally friendly, balancing practicality and environmental protection needs, and interpreting the quality and value of custom lunch tin boxes with precise data.
