Tinplate Strip Overview
What Is Tinplate Steel Strip
Steel Base
You start with a strong steel base when you choose tinplate strip for packaging. This steel base gives the material its strength and formability. Manufacturers use high-quality steel that meets strict standards, such as JIS G 3303-2002 and ASTM A623M-2002. These standards ensure that the steel base remains consistent and reliable for food packaging.
- Grades available include MR, SPCC, SPHC, and Q195.
- The steel base provides the foundation for the tin coating, supporting the structure of cans and containers.
Tin Coating
A thin layer of pure tin covers both sides of the steel strip. This tin coating acts as a protective barrier against moisture and air. You benefit from this layer because it prevents rust and oxidation, which can spoil food. Tin is non-toxic, so it is safe for direct contact with food and beverages. The tin layer also gives the packaging a shiny, attractive finish that appeals to consumers.
Tip: The dense tin coating keeps the steel from corroding, which is essential for preserving the freshness and taste of packaged foods.
Key Properties
Strength
You need packaging that can withstand handling, shipping, and storage. Tinplate steel strip delivers excellent strength and durability. The combination of steel and tin creates a material that resists dents and deformation. This strength protects your food from physical damage and keeps it safe until you open the package.
| Temper | EN10202 | ASTM 623 | JIS G3303 | Yield Strength (Mpa) | Tensile Strength (Mpa) | Allow Tolerance (Mpa) ± |
|---|---|---|---|---|---|---|
| TH340 | TH340 | T3 | T3 | 340 | 360 | 40 |
| TH360 | TH360 | T3.5 | T3.5 | 360 | 380 | 40 |
| TH380 | TH380 | T3.5 | T3.5 | 380 | 400 | 40 |
| TH415 | TH415 | T4 | T4 | 415 | 415 | 40 |
Corrosion Resistance
You want your food to stay fresh for as long as possible. The tin coating on tinplate strip provides outstanding corrosion resistance. This property keeps air and moisture out, which helps maintain the quality and flavor of your food. The non-toxic nature of tin makes it ideal for food packaging. You can trust that your food remains safe and uncontaminated.

Preserving Freshness & Taste
Barrier Protection
Moisture Block
You need packaging that keeps moisture away from your food. Tinplate strip forms a tight seal that blocks water vapor from entering the container. This barrier helps prevent sogginess and spoilage, especially for products like crackers, dried fruits, and powdered foods. The high contact angle of the tin coating reduces the adhesion of water and salt particles, which means your food stays dry and fresh even in humid environments.
| Parameter | Value | Significance |
|---|---|---|
| Corrosion inhibition efficiency | >99.8% | Strong protection against corrosion |
| Z | 0.01 Hz after 144h | |
| Z | 0.01 Hz after wet-dry cycles | |
| Contact angle | High | Reduces adhesion of sodium chloride particles |
| Ice inhibition effect | Good | Enhances performance under cold conditions |
Note: The moisture-blocking ability of tinplate steel strip helps maintain the texture and quality of your food from the factory to your table.
Oxygen Block
Oxygen can cause food to lose flavor and spoil quickly. You want packaging that keeps oxygen out. Tinplate steel strip acts as a powerful shield, preventing oxygen from reaching the food inside. This protection is especially important for products like juices, teas, and canned vegetables, where preserving original taste and nutrients matters most.
- Tinplate cans block light and oxygen, making them ideal for beverages that need to retain their original flavor.
- The tin coating prevents the contents from reacting with the steel, preserving both flavor and nutritional value.
- Effective packaging solutions like tinplate steel strip help food items keep their taste, nutritional value, and safety from production to pantry.
Corrosion Resistance
Rust Prevention
You expect your food packaging to resist rust and keep your food safe. The tin coating on tinplate steel strip provides outstanding corrosion resistance. Laboratory research shows that steel strips with protective coatings, like tin or chromium, resist corrosion and staining, even in challenging environments. This means your food stays uncontaminated and fresh, even after long periods in storage.
Long-Term Storage
You want your food to last as long as possible without losing quality. Tinplate steel strip offers superior long-term corrosion inhibition compared to bare tinplate. The high resistance to corrosion, even after wet-dry cycles, ensures that your food remains safe and tasty over time. This makes tinplate steel strip a reliable choice for products that require extended shelf life, such as canned meats, fruits, and ready-to-eat meals.
Tip: The ice inhibition effect of tinplate steel strip enhances its performance in cold storage, making it suitable for a wide range of food products.
Contamination Prevention
Food Safety
You need packaging that protects your food from contamination. Tinplate steel strip creates a robust barrier against bacteria, pests, and environmental hazards. This strong protection ensures that your food remains safe for consumption throughout storage and transport.
- Tinplate cans provide a strong barrier against oxygen, moisture, and light, which helps keep food fresh and reduces spoilage.
- The robust nature of tinplate packaging protects food from contamination by bacteria and pests, ensuring safe consumption.
- Tinplate cans are stackable and compact, minimizing space requirements and reducing the risk of damage during transit.
Bacterial Inhibition
You want to avoid bacterial growth in your packaged food. The non-porous surface of tinplate strip makes it difficult for bacteria to penetrate or multiply. This property, combined with the airtight seal, helps inhibit the growth of harmful microorganisms. As a result, your food stays safer for longer, giving you peace of mind every time you open a can or container.
Tinplate Steel Strip vs. Other Materials
Plastic Comparison
Taste Retention
When you choose packaging, taste retention matters. Plastic containers can sometimes allow air and odors to seep in, which may affect the flavor of your food. In contrast, tinplate steel strip forms a complete barrier against air, moisture, and light. This barrier helps preserve the original taste and aroma of your food, making it a preferred choice for products where flavor is critical.
Environmental Impact
You want packaging that supports a healthier planet. Tinplate strip stands out with a recycling rate exceeding 90% in countries like Germany.
