Chemical tin cans are customized for the storage and transportation of industrial chemical materials. This article elaborates on substrate specifications, physical parameters, tolerance indicators and industrial compliance standards purely from the parameter perspective. Made of national standard customized tinplate, the regular substrate thickness ranges from 0.23mm to 0.32mm, which can be adjusted according to material density. The tensile strength remains stably above 320MPa with qualified deformation resistance. Standardized dimensional parameters cover volumes from 50ml to 5000ml. The dimensional tolerance is strictly controlled within ±0.5mm to adapt to automatic filling lines and standardized storage shelves.

　　The sealing structure adopts a 2.8mm overlapping edge and four-fold crimping technology, achieving zero leakage within 24 hours under normal pressure. The built-in sealing ring withstands temperatures from -30℃ to 70℃ with an aging resistance test duration of over 800 hours. The static compression load capacity reaches 120kg, and the side impact resistance meets industrial transportation standards to avoid damage during transit. The seamless welding seam has a higher pressure resistance threshold to resist acid and alkali penetration without tiny pores.

　　The inner anti-corrosion coating has a dry film thickness of 25μm to 35μm, resisting acid, alkali and organic solvents for storing liquid reagents and chemical powders. The outer baking paint with a uniform thickness of 40μm passes a 48-hour salt spray test without oxidation, adapting to humid warehouses and sea transportation. All cans comply with chemical packaging safety standards without heavy metal precipitation. Physical indicators such as plate thickness, volume and coating material support personalized customization. With controllable physical parameters, strict detection indicators and standardized specifications, these chemical tin cans deliver stable performance, serving as professional metal containers for industrial chemical packaging and cross-border transportation.
