　　In terms of core materials and production technology, custom lunch tin boxes with handles adopt food-grade high-quality tinplate (tinned steel sheet) as the main raw material. The base material features uniform thickness and excellent toughness, contains no harmful substances such as lead and mercury, and fully complies with international food contact safety standards. It can directly carry various ingredients such as cooked food, snacks, dried fruits and baked food with safety and no peculiar smell. The dense tin plating protective layer on the tinplate surface delivers excellent rust prevention, corrosion resistance and oxidation resistance, which can effectively isolate air, water vapor, dust and bacteria, preventing food from moisture deterioration and oxidative mildew. Compared with plastic lunch boxes, it is more suitable for long-term storage and repeated use. In terms of production technology, the product adopts an integral stamping forming process with seamless splicing and compact structure. All edges are polished and rounded for multiple times with smooth and burr-free surface, avoiding hand scratching and bag tearing. The handle adopts reinforced welding, integral bending or buckle fixing technology, which is closely fitted with the box body with strong bearing capacity, preventing falling and deformation during long-term frequent carrying. Meanwhile, the box cover adopts a precision occlusive sealing design with smooth opening and closing and excellent sealing performance, which can effectively lock food freshness, realizing outstanding dustproof, moisture-proof and leak-proof fresh-keeping effects.

　　Customized design is the core competitiveness of custom lunch tin boxes with handles and the key advantage to adapt to full-industry scenarios.
