The charm of a vintage metal lunch box lies not only in its nostalgic design that evokes warm memories, but also in the absolute safety and reliability backed by authoritative safety certifications. In an era where food safety and product quality are highly valued, a vintage metal lunch box without recognized safety certifications can never truly win the trust of users. As a professional manufacturer specializing in vintage metal lunch boxes, we take safety as our top priority, and every product we launch has passed a series of rigorous international and national safety certifications. These certifications are not just labels, but tangible guarantees of our commitment to safety, ensuring that every vintage metal lunch box is non-toxic, harmless, and safe for long-term use, allowing users to enjoy their meals with peace of mind while embracing the nostalgic charm of the vintage design.

　　Our vintage metal lunch boxes have obtained the ISO 22000 food safety management system certification, a globally recognized benchmark for food safety. This certification covers every link from raw material procurement, production processing to finished product delivery, ensuring that our entire production process complies with international food safety standards. It requires strict control of food contact materials, production environment hygiene, and process standardization, eliminating any potential hazards that may affect food safety. In addition, we have obtained the FDA (Food and Drug Administration) certification from the United States, which is one of the most authoritative food safety certifications in the world. This certification confirms that our vintage metal lunch boxes are made of food-grade materials that are non-toxic, odorless, and free of harmful substances, and can be safely in direct contact with food, even for long-term use.

　　For the European market, our vintage metal lunch boxes have passed the EU REACH certification and LFGB certification, two core safety certifications for food contact materials. The REACH certification strictly restricts the use of harmful chemicals, ensuring that our products do not contain any substances that are harmful to human health or the environment. The LFGB certification, known as the "gold standard" for food contact materials in the EU, requires strict testing of material safety, including heavy metal residues, harmful substance release, and odor. Our vintage metal lunch boxes have passed all these tests with excellent results, with heavy metal residue content ≤0.0008mg/kg, far below the EU limit of ≤0.01mg/kg, and no harmful substances released even when in contact with high-temperature food, fully meeting the strict safety requirements of the European market.

　　In addition to international certifications, our products also comply with national safety standards and have obtained relevant domestic certifications, including the national food contact metal material safety standard (GB 4806.9-2016) certification. This certification ensures that our vintage metal lunch boxes meet the safety requirements of the domestic market, with materials, craftsmanship, and performance all up to standard. We also conduct regular third-party testing, inviting authoritative testing institutions to conduct random inspections on our products to ensure that the safety performance of each batch of products is consistent with the certification standards. Every vintage metal lunch box is marked with clear certification logos, allowing users to check and verify at any time. From the selection of food-grade metal materials to the strict control of the production process, and the recognition of various authoritative certifications, we use professional strength to build a solid safety barrier for our vintage metal lunch boxes. These safety certifications not only prove our product quality, but also let every user feel that while enjoying the nostalgic charm of the vintage design, they can also have absolute peace of mind about food safety, making our vintage metal lunch boxes the perfect combination of nostalgia and safety.
