Shandong Sino New Material Co., Ltd. specializes in manufacturing premium electrolytic tinplate coils specifically engineered for food packaging applications. Our factory-direct supply model ensures cost-effective solutions without compromising on the stringent quality standards required for food safety. With ISO-certified production processes and customizable specifications, we provide reliable material for creating durable, corrosion-resistant food containers that meet global regulatory requirements.
Electrolytic tinplate combines the strength of steel with the protective qualities of tin, creating an ideal substrate for food preservation. The electrolytic deposition process allows precise control over coating thickness, resulting in uniform coverage that prevents metal exposure and ensures consistent performance during can forming and sealing operations.
Key Technical Specifications:
| Parameter | Standard Range | Custom Options |
|---|---|---|
| Base Hardness | T2.5-T3.5 | T1-T5 available |
| Coating Structure | Differential or Equal | Per customer request |
| Passivation Type | Chromium-based | Custom formulations |
| Oil Content | 2-5 mg/m² | DOS or ATBC oils |
Manufacturing Advantages:
Advanced Production Control: Continuous monitoring of coating uniformity through X-ray fluorescence gauges
Enhanced Corrosion Resistance: Chromium passivation layer prevents sulfide staining
Superior Formability: Optimized temper grades for seamless can body forming
Consistent Welding Performance: Low surface roughness enables reliable seam welding
Eco-Friendly Processing: Lead-free and heavy metal-free composition
Our manufacturing capabilities include specialized annealing treatments that optimize the microstructure for deep drawing applications. The recrystallization process enhances ductility while maintaining adequate strength for stacking and transportation. Each coil undergoes rigorous inspection including:
Coating weight verification at multiple points
Adhesion testing via bending and impact tests
Surface defect detection through automated scanning
Chemical composition analysis
Mechanical property validation
Packaging and Logistics:
Coils are protected with:
Inner moisture-proof barrier
Steel edge guards
Weather-resistant outer wrapping
Custom labeling per shipment requirements
Available shipment through Qingdao, Tianjin, or Shanghai ports with flexible incoterms including FOB, CFR, and CIF.

Frequently Asked Questions:
Q: What's the typical lead time for orders?
A: Standard specifications ship within 20-30 days after order confirmation. Custom requirements may extend lead time by 7-10 days.
Q: Can you provide material certification documents?
A: Yes, we supply Mill Test Certificates with each shipment, including chemical composition, mechanical properties, and coating measurements.
Q: Do your products meet FDA requirements for food contact?
A: Our tinplate coils comply with FDA CFR 21.175.300 for food contact applications.
Q: What's your quality control process?
A> We implement 4-stage quality checks: raw material inspection, in-process monitoring, pre-shipment testing, and final lot verification.
Q: Can I request specific tin coating distribution?
A: Yes, we can produce differential coatings (different thickness on each side) or equal coatings per your specifications.
Q: How do you prevent corrosion during ocean transit?
A: We use VCI (Vapor Corrosion Inhibitor) packaging and desiccant units for extended sea voyage protection.
Q: What file formats do you provide for technical drawings?
A> We can supply specifications in PDF, DWG, or DXF formats upon request.
Q: Do you offer technical support for can production troubleshooting?
A: Our metallurgy team provides complimentary technical consultation for material-related forming or welding issues.
