Nine Years of Coating Leadership
Dongke Electric Heating has been operating since 2017. That gives us nine years of manufacturing experience. Our R&D team developed the coating formula and spraying process independently. We own the intellectual property rights. We produce 10,000 cups per day. Our coating line produces zero VOC emissions. Leading brands in China have approved our coating for mass production.
Medical-Grade Steel for Acidic Foods
The stainless steel lunch bento uses a higher-grade material. The body is made of 316L medical-grade stainless steel. Compared with 304 stainless steel, this material provides better resistance to acids and corrosion. This is important for certain foods. Curry, kimchi, and pickled vegetables are acidic and may affect ordinary stainless steel over long-term use. They may also cause metal ions to migrate into food. 316L stainless steel provides better protection in these situations.
The box features our hydrophilic coating on all surfaces. The coating is dense and nearly pore-free. Oil and sauce residues have difficulty adhering to the surface. When you rinse the box, water spreads into a complete film. This water film lifts grease away from the wall. The stainless steel lunch bento stays clean with just one rinse. Even after storing curry or kimchi, it does not retain smells or colors. You can pack lighter foods the next day without unwanted flavors.
Warm Food Until Noon
The coating also helps inhibit bacterial growth. The vacuum insulation layer keeps food warm for several hours. The box is lightweight and easy to carry. This lunch box is suitable for office workers and students. We target the commuter hot food market in North America, Europe, and the Middle East. We offer OEM and ODM services. We support logo customization, packaging customization, and style customization. We provide samples before mass production. The minimum order quantity is 1,000 pieces. We offer a 12-month warranty. Repeat orders have delivery times that are 5 to 10 days shorter than the first order.
