2026-08-10

1. Product Introduction of 502D 127mm Tinplate Bottom Ends

The 502D 127mm tinplate bottom ends are industry-standard, large-diameter metal bases engineered for wide-mouth, large-capacity food cans. Crafted with premium ETP tinplate and TFS tin-free steel, this 127mm specification features a reinforced 502D crimp structure that fits most industrial high-volume canning lines perfectly. Unlike conventional small-sized can bottoms, this model boasts enhanced structural strength to withstand greater pressure and stacking loads, making it a practical, cost-effective choice for bulk food packaging applications.

Every 502D 127mm tinplate bottom end is finished with BPA-free food-grade inner lacquer, with golden coating, white enamel and aluminized lining options available. Fully compliant with international food contact safety standards, these reliable metal bases support long-term safe storage for powdered goods, oily ingredients, cured meat, seafood and pickled produce. They effectively resolve common packaging challenges for large food cans, including poor sealing performance and internal corrosion risks.

2. Core Product Performance & Advantages

2.1 Reinforced Structural Stability for Large-Can Loads

Large-volume food cans demand robust structural support to avoid deformation during stacking, transportation and prolonged storage. Our 502D 127mm tinplate bottom ends adopt an upgraded reinforced ring design and precision stamping craftsmanship, delivering a solid, flat and stable structure. They efficiently resist extrusion distortion and bottom bulging, maintaining complete structural integrity throughout long-haul logistics and high-stack warehousing. This durable design greatly cuts packaging damage rates for large-format food cans in mass production and distribution.

2.2 Multi-Scenario Anti-Corrosion & Barrier Protection

We equip these large tinplate bases with customizable functional inner coatings to deliver targeted protection for different food types. The oil-resistant lining effectively defends against grease erosion for edible oil and fatty food cans; the moisture and oxidation-proof coating preserves dryness and freshness for milk powder, nutritional supplements and grain powder products; the acid and salt-tolerant formula suits canned meat, seafood and pickled vegetable packaging. This tailored protection prevents metal rust, coating peeling and food spoilage caused by long-term ingredient contact.

2.3 Strict Food-Grade & BPA-Free Safety

Food safety stands at the core of HJ GROUP’s product design for 502D 127mm tinplate bottom ends. All raw materials and surface coatings are non-toxic, odor-free and fully BPA-NI compliant, passing authoritative international food safety testing. No harmful substances leach out even after continuous contact with various foods, ranging from infant formula and nutritional powder to edible oil and preserved delicacies. These bases meet the strict packaging criteria of premium food brands and global export regulations.

2.4 Airtight Sealing & Long Shelf-Life Guarantee

Featuring standardized 502D crimping technology and seamless smooth edges, our 127mm tinplate bases fit tightly with matching large can bodies. They create a sturdy protective barrier against external moisture, air, dust and unwanted odors. Whether used for vacuum-packed meat cans, air-sealed powder containers or oil storage tins, these bases deliver consistent airtight performance. This stable sealing capability significantly extends the shelf life of bulk food goods and reduces inventory waste for food manufacturers.

2.5 High Compatibility & Industrial Production Efficiency

As a universally recognized standard large-size specification, 502D 127mm tinplate bottom ends work seamlessly with most mainstream automatic crimping and can sealing equipment on the market. With consistent caliber dimensions and reliable crimping stability, they adapt perfectly to high-speed industrial mass production, minimizing manual adjustments and lowering defective sealing rates. Ideal for standardized batch manufacturing of various large food cans, these efficient packaging components help food factories boost overall productivity and streamline production workflows.

3. Wide Application Scope
