Corrosion Resistance Empowerment, Long-Term Durability — Small Oval Tin Box, with super corrosion resistance as the core highlight, relies on professional craftsmanship and high-quality materials to resist various corrosion hazards, combining a small and exquisite appearance with long-lasting durability, becoming the preferred item for storage, gifts, food packaging and other scenarios. We specialize in the R&D and production of small oval tin boxes, and deeply understand that corrosion resistance is the key to determining the service life of products. Aiming at the corrosion risks of different use scenarios, we have built a comprehensive corrosion resistance protection system, strictly controlling every link from material selection to process upgrading, so that each small oval tin box can resist corrosion tests such as moisture, acid and alkali, oxidation, and effectively protect the internal items intact for a long time.

　　The core corrosion resistance guarantee comes from the strict selection of high-quality base materials. High-specification corrosion-resistant cold-rolled iron plate is selected, which has undergone special alloy ratio treatment with an impurity content ≤0.01% and a dense and uniform texture, improving the corrosion resistance of the base material itself from the source. Compared with ordinary iron plates, the corrosion resistance is improved by more than 60%, which can effectively resist the erosion of water vapor and oxygen in the air, avoiding rust, oxidation and other problems. At the same time, the thickness of the base material is accurately adjusted to 0.25-0.32mm, which not only ensures the small and exquisite texture of the product, but also enhances the corrosion resistance and toughness of the material, making it not easy to be damaged or deformed due to corrosion, and adapting to long-term use and various storage scenarios.

　　Supported by multiple professional corrosion-resistant processes, a comprehensive protective barrier is built. The chrome-free passivation corrosion-resistant process is adopted to form a dense protective film on the surface of the base material, which is closely attached to the base material, effectively isolating corrosive media such as water vapor, acid and alkali substances, and salt, eliminating corrosion hazards. At the same time, it meets environmental protection standards with no harmful residues, suitable for the storage of various items such as food and jewelry. An additional environmental protection corrosion-resistant film is added on the surface, selecting high-adhesion PET corrosion-resistant film, which is high-temperature and acid-alkali resistant, further improving the corrosion resistance of the product, and at the same time playing a role in scratch and wear resistance, allowing the appearance of the tin box to remain intact for a long time, not easy to fade, film peeling, rust and other situations.

　　The corrosion resistance is suitable for various scenarios. Whether it is a humid kitchen, a stuffy storage room, or food storage and outdoor carrying in contact with slight acid and alkali, the small oval tin box can stably exert its corrosion resistance advantage and effectively protect internal items for a long time. Each batch of products has undergone professional corrosion resistance testing, simulating different corrosion environments for aging tests, ensuring that the products still maintain excellent corrosion resistance during long-term use, with a qualification rate of more than 99.9%. The small and exquisite oval shape combined with super corrosion resistance makes this tin box not only have the advantage of appearance, but also have durable strength, suitable for various scenarios such as gift customization, daily storage, and food packaging, showing product quality and practicality with corrosion resistance hard power.
