In industrial applications, tinplate plate thickness generally ranges from 0.13 mm to 0.50 mm, with different thicknesses suiting different packaging needs and applications.
1. Tinplate Thickness Range
Tinplate thickness varies depending on its intended use. Generally, thinner tinplate is used for packaging that requires lightness and flexibility, while thicker tinplate is used for product packaging that requires greater strength and durability. Specific thickness ranges are as follows:
• Thin tinplate: 0.13 mm to 0.20 mm
• Medium-thick tinplate: 0.21 mm to 0.30 mm
• Thick tinplate: 0.31 mm to 0.50 mm
2. Thickness Units and Measurement Methods
In industry, tinplate thickness can be accurately measured using a micrometer or precision thickness gauge. Precise thickness control is crucial to ensuring the product's corrosion resistance and mechanical properties. Furthermore, tinplate thickness directly affects its processing ease and molding quality, so careful consideration should be given to the product's design requirements when selecting the tinplate thickness.

1. Thin Tinplate (0.13mm to 0.20mm)
Thin tinplate is primarily used for packaging products that require lightweighting. Due to its thinness, thin tinplate plate is easier to process into complex shapes, while also reducing material consumption and transportation costs during production. Typical applications of thin tinplate plate include:
1.1 Food and Beverage Cans
Thin tinplate sheet is widely used in the manufacture of food and beverage cans, particularly in the beverage industry, such as carbonated drinks and beer cans. Its lightweight and excellent sealing properties make it an ideal choice for beverage packaging. Its lightweight nature not only helps reduce shipping costs but also makes it easier for consumers to carry and use. Furthermore, its surface coating effectively isolates oxygen and moisture, extending the shelf life of food and beverages.
1.2 Biscuit and Candy Packaging
The lightweight and corrosion-resistant nature of thin tinplate sheet makes it ideal for food packaging, such as biscuit and candy boxes. These packaging not only ensures the quality of the contents but also offers a certain aesthetic appeal, often enhanced through printing and decorative techniques. Since biscuits and candies require less mechanical strength, thinner tinplate plate is sufficient.
1.3 Cosmetic and Perfume Containers
Some high-end cosmetic and perfume bottle caps are also made from thin tinplate plate. Thin tinplate plate allows for precise stamping and forming, resulting in a smooth, textured surface, making it ideal for products requiring aesthetically pleasing packaging. Furthermore, tinplate plate's printability allows manufacturers to create intricate designs, enhancing the product's market appeal.
2. Medium-Thickness Tinplate Sheet (0.21 mm to 0.30 mm)
Medium-thickness tinplate sheet is common in industrial applications because it combines strength with good workability. Medium-thickness tinplate sheet allows for complex processing and printing while maintaining sufficient strength. The following are typical uses for medium-thickness tinplate sheet:
2.1 Canned Food Packaging
Canned food packaging is one of the primary applications for medium-thickness tinplate sheet. Canned foods typically require extended storage periods and must withstand temperature fluctuations and external pressure, placing high demands on the packaging material's strength and sealing properties. Medium-thick tinplate sheets provide sufficient strength to withstand the stresses of transportation, storage, and processing, ensuring that the contents remain contaminated during long-term storage.
2.2 Paint Cans and Chemical Packaging
Paints and chemicals are often corrosive, so their packaging materials must possess both excellent corrosion resistance and strength. Medium-thick tinplate sheets excel in this application, as their tin layer effectively prevents corrosive substances from corroding the steel substrate. Compared to thinner tinplate sheets, medium-thick tinplate sheets offer greater impact resistance, providing additional protection during transportation and storage.
2.3 Canned Bottle Caps and Closures
Middle-thick tinplate sheets are commonly used for bottle caps and closures in many canned food or beverage packaging. This is because bottle caps must not only provide a good seal but also possess sufficient strength to maintain deformation during opening and closing. Medium-thick tinplate sheets meet these requirements. Furthermore, their plasticity allows for a variety of bottle cap designs to suit different product packaging needs.
3. Thick Tinplate Sheet (0.31mm to 0.50mm)
Thick tinplate sheet offers high strength and rigidity, making it suitable for industrial packaging that must withstand high forces or harsh environments. Its primary applications are in the chemical, construction, and large container manufacturing industries, where high strength is required. The following are typical uses for thick tinplate sheet:
3.1 Large Paint Cans and Chemical Containers
Thick tinplate sheet is particularly suitable for manufacturing large paint cans, chemical containers, and storage tanks. These products must hold corrosive liquids for extended periods and withstand significant impact and pressure during transportation. Thick tinplate sheet's high strength and excellent corrosion resistance provide reliable protection for their contents in these harsh environments.
3.2 Construction and Decoration Materials

Tinplate sheet's smooth surface and ease of coating complement architectural designs, while its thickness provides strength and durability.
3.3 Industrial Packaging Containers
Some large mechanical parts, tools, or industrial products requiring long-term storage also use thick tinplate sheets as outer packaging. Thick tinplate sheets not only provide excellent pressure resistance but also protect the contents from environmental factors such as moisture and oxidation.
How to Choose the Right Tinplate Sheet Thickness?
When selecting tinplate sheet thickness, manufacturers and designers need to make decisions based on the specific requirements of the product. Choosing the right tinplate sheet thickness ensures both safety and cost-effective packaging. The following factors should be considered:
