Bulk stackable square tin boxes are positioned at bulk storage and efficient storage. Their data index design is scientific, standardized and accurately controllable. Each index has been strictly measured and batch tested, balancing stacking stability, durability and batch adaptability, adapting to the bulk storage and turnover needs of food, stationery, hardware and other industries. With standardized data index configuration, they have become the preferred products for bulk storage and turnover. Their data indicators cover various dimensions such as size data, stacking data, material data, durability data and batch adaptability data. The indicators are accurately marked without redundancy and any consulting inducement content, comprehensively presenting the core data of the product, highlighting the practicality and reliability of bulk use.

　　Size data is suitable for bulk stacking and storage, adopting a standardized square design. The core specifications of bulk supply are uniform, with an error strictly controlled within ±0.05cm, ensuring close fit and no inclination during bulk stacking. Core size parameters: 20cm×20cm×10cm (basic model), 25cm×25cm×12cm (enlarged model). Both specifications adopt a square proportional design, with a box flatness of ≤0.03cm and a bottom flatness of ≤0.02cm, ensuring uniform force during stacking and avoiding during bulk stacking. The wall thickness of the box body is 0.32cm, uniform without deviation, which not only ensures structural firmness but also controls the overall weight, adapting to bulk handling and warehouse turnover.

　　Stacking data is the core highlight, designed specifically for bulk stacking scenarios. The single box stacking load-bearing capacity is ≥50kg, which can be stably stacked for 8-10 layers. The total height of bulk stacking can reach 80-100cm, and the overall vertical deviation after stacking is ≤0.5cm, without inclination or collapse risk, adapting to bulk storage on warehouse shelves and greatly saving storage space. The top and bottom of the box body are equipped with precise positioning grooves and bosses, with a groove depth of 0.8cm and a boss height of 0.8cm, and the fitting gap is ≤0.05cm, which can be accurately engaged during stacking, preventing sliding and misalignment, and reducing wear during stacking, adapting to long-term bulk turnover use.

　　Material data balances durability and bulk use needs. The box body is made of food-grade tinplate, with a material density of 7.85g/cm³, a tensile strength of ≥320MPa, a yield strength of ≥280MPa, and an impact resistance of ≥15J/cm², which can withstand extrusion and collision during bulk handling and stacking, and is not easy to be dented, deformed or damaged. The surface adopts an environmentally friendly electrostatic spraying process, with a coating thickness of 0.08-0.1cm, an adhesion of ≥4 levels, a scratch resistance of ≥500 times, and a corrosion resistance meeting the GB/T 10125-2021 standard. It is not easy to rust, peel off or fade during long-term bulk storage or turnover, maintaining a clean appearance.

　　Durability and batch adaptability data fit actual needs. The service life of a single box is ≥3 years (under bulk turnover scenarios), the number of opening and closing times is ≥10,000, and the sealing performance meets the standard. The gap after closing is ≤0.03cm, which can effectively isolate dust and moisture, adapting to bulk storage of dry goods, stationery and other items. Batch adaptability data: 20 pieces per box for single box packaging, each box weight ≤15kg, and the box size is 42cm×42cm×22cm (basic model), adapting to standard logistics turnover boxes, facilitating bulk transportation and warehouse inventory; the batch production error is ≤1%, ensuring that the data of each batch of products is uniform, adapting to large-scale bulk use scenarios.
