The Tinplate Rectangular Tin Bottom is a high-performance container bottom component widely used in industrial and food packaging applications. Made from high-quality tinplate using precision processes such as stamping, hemming, and welding, it is widely suitable for metal packaging containers, including square, rectangular, oblong, and F-style oil tanks. Its greatest advantage lies in combining the sturdiness of tinplate with the space-efficient rectangular structure, resulting in high safety and durability during storage and transportation.

Tinplate Rectangular Tin Bottom Product Features
1. Strong Sealing Performance
The rectangular bottom utilizes a high-precision hemming process with a hemming accuracy of ±0.05mm, ensuring a tight seal between the square, rectangular, or F-style can body and the bottom. Whether used for chemical liquids or edible oil, it effectively prevents leakage and meets industrial-grade sealing standards.
2. High Corrosion Resistance
The tinplate base is ≥0.23mm thick and coated with a gold or white interior finish to resist corrosion from acids, alkalis, salts, and oils. With the paint coating intact, the product lifespan can be extended to over five years, making it suitable for long-term storage and ocean transportation.
3. High Pressure-Bearing Capacity
The rectangular structure offers excellent pressure resistance. When stacked vertically, it can withstand pressures of 300 kg or more without deformation, making it particularly suitable for large-capacity 18L oil tanks and chemical packaging. Compared to round tank bottoms, square and oblong bottoms offer more even force distribution and greater stability during transportation.
4. Optimized Space Utilization
The rectangular and square tank bottom designs increase container space utilization by 12%-15%. For example, a 20-foot container can hold approximately 200 more 18L square tanks than a round one, significantly reducing logistics costs.

Tinplate Rectangular Tin Bottom Applications
1. Edible Oil Packaging
Rectangular tin bottoms are widely used in metal can packaging for edible oils such as olive oil, peanut oil, and sunflower oil. The F-style end design not only provides a strong seal but also prevents oil leakage caused by temperature fluctuations during transportation.
2. Lubricant and Industrial Oil Storage
Square and oblong ends are widely used for packaging industrial oils such as engine oil, hydraulic oil, and gear oil. The rectangular structure ensures efficient stacking during storage and loading and unloading, reducing storage space.
3. Chemical Transportation and Storage
Suitable for chemical liquids such as detergents, solvents, and pesticides. The highly corrosion-resistant coating ensures long-term storage of even acidic or alkaline liquids without leakage or corrosion.
4. Paint and Varnish Packaging
In the packaging of paints, varnishes, and coating materials, the tight seal of the rectangular tin bottom prevents the volatilization of organic solvents, ensuring safe transportation and coating quality.
5. International Export and Long-Distance Ocean Shipping
The F-style bottom is particularly suitable for long-distance export. Its sturdy bottom and corrosion-resistant inner coating can withstand high humidity and salt spray environments. Industrial oils exported in large quantities to Southeast Asia, Africa, and the Middle East all utilize this type of rectangular bottom can.
6. Food and Beverage Auxiliary Packaging
Some coffee powder, syrup, and seasoning liquid packaging also utilize square-bottom tin cans, ensuring shelf stability and a premium appearance.
