It serves as a compliant exclusive packaging solution for baking factories, food traders, brand gift box enterprises and cross-border e-commerce.

　　The substrate strictly complies with the food-grade tinned tinplate compliance standard to lay a solid foundation for food contact safety. Brand-new primary original tinplate is adopted throughout the process without doped recycled iron or waste materials, fundamentally eliminating hidden dangers of heavy metal residues and impurity pollution. The substrate thickness is stable and uniform with a conventional standard thickness of 0.20mm–0.28mm, featuring compact structure and excellent toughness. The formed box body is flat and square with outstanding compression resistance, which can withstand the extrusion pressure of stacking storage and transportation, avoid deformation and damage of gift boxes during transportation, and prevent cookie moisture deterioration caused by packaging cracking. The original tinplate is processed by professional tin plating technology with uniform and dense tinned layer, no missing plating or pinhole defects, complying with the safety specifications of food contact metal materials. The material has stable inertia and will not chemically react with grease, sugar and dairy products in cookies, with no risk of metal precipitation or food pollution. Meanwhile, the metal substrate has full light-shielding and oxygen-isolating properties, which can effectively block the invasion of light, air and moisture, lock the crispy taste of cookies for a long time, solve the problems of moisture softening, oxidation and rancidity of cookies during long-term storage, and adapt to compliant storage requirements in multiple scenarios such as normal temperature warehousing, supermarket display and long-distance cold chain transportation.

　　The inner wall protective coating adopts food-grade non-toxic environmentally friendly coating, which fully meets the compliance requirements of baked food packaging. Abandoning traditional inferior industrial oil-based coatings, it selects food-contact special water-based protective resin, which is benzene-free, formaldehyde-free, heavy metal-free and harmful solvent-free. It has passed national food packaging safety testing and can be in direct contact with oily and sugary foods such as various cookies and pastries. The coating has strong adhesion and uniform and dense film formation, completely covering the metal surface of the tin box inner wall to form an isolation protective layer. It thoroughly isolates the direct contact between the metal substrate and food, effectively prevents high-oil and high-sugar food from corroding metals, and eliminates hidden compliance risks of coating falling off and debris polluting food. After curing, the coating has no peculiar smell, no volatilization and no penetration, and is resistant to high temperature and normal temperature storage. It is suitable for long-term sealed storage of cookies, fully meets domestic GB food contact standards, and adapts to international food contact compliance requirements such as EU LFGB and US FDA, ensuring qualified safety of domestic and export products.

　　The appearance printing and surface technology fully implementenvironmental protection compliance standards to avoid hidden risks of food packaging printing violations. All patterns, LOGOs, texts and parameter printing adopt food packaging special environmentally friendly soybean ink, replacing traditional chemical ink. It has the advantages of low VOC, no pungent peculiar smell, non-toxic and harmless, no harmful substance precipitation, fully complying with food packaging environmental protection compliance specifications. The ink has uniform color development and strong adhesion, wear-resistant and scratch-resistant, no fading or falling off during long-term display, and will not produce dust to pollute cookies inside the box. High-end processes such as matte film covering, bright coating, hot stamping and embossing are optional for the surface, and all supporting auxiliary materials are food packaging compliant materials without harmful chemical residues or pungent odor. It completely abandons waste ink and inferior film covering materials, thoroughly avoids common food packaging quality inspection problems such as excessive printing, unqualified materials and substandard environmental protection, ensuring that products can successfully pass qualification audits for offline supermarket shelf placement, online platform sales and cross-border export.

　　The structural design and sealing protection take into account use safety compliance and storage and transportation specifications. The tin box adopts rounded corner passivation technology, with finely polished and burr-free edges, avoiding hand scratches and outer bag damage caused by sharp corners, complying with consumer product safety protection specifications. The box cover and box body have moderate tightness and smooth opening and closing, adapting to automatic packaging production lines and manual operation without jamming, loosening or falling off hidden dangers. Food-grade silica gel sealing strips are optional. Made of special food-contact materials, the strips are non-toxic and tasteless, aging-resistant and temperature-resistant, no deformation or cracking after repeated opening and closing. They can effectively improve the box tightness, block the invasion of dust, moisture, mosquitoes and peculiar smell, and keep the stored cookies clean and dry. The regular rectangular structure has high space utilization rate, and the standardized size adapts to the conventional warehousing, stacking and packaging transportation specifications of the food industry. It is stable in stacking and not easy to pour, reducing storage and transportation losses and complying with the warehousing safety management standards of food enterprises.

　　The whole-process quality control testing builds acomplete compliance qualification system with traceability, verifiability and customs clearance availability. Before warehousing, raw materials are sampled and inspected batch by batch for compliance indicators of materials, coatings and inks to prevent unqualified raw materials from being put into production. The production process strictly implements dust-free workshop production standards to avoid food packaging pollution by dust and impurities during production. Before factory delivery, finished products complete air tightness testing, material safety testing, heavy metal content testing and volatile substance testing. Each batch of products can provide corresponding food contact test reports, material compliance certificates and environmental protection qualification documents. The complete set of qualifications adapts to various scenarios such as domestic market quality inspection random inspection, supermarket entry audit, brand factory inspection and cross-border customs clearance, thoroughly solving the industry pain points of food packaging such as no qualification, non-compliance, failure to clear customs and failure to shelf. Meanwhile, the reusable and recyclable tin box features low carbon and environmental protection with no solid waste pollution, complying with domestic and foreign food packaging environmental protection policies and sustainable development compliance requirements.
