PACKFINE’s 202 SOT (Stay-on-Tab) aluminum ends are engineered from high-strength 5182-H19 alloy to ensure maximum seal integrity. Designed for carbonated beverages and craft beers, these lids withstand internal pressures up to 90 PSI (6.2 Bar). Fully compliant with FDA and BPANI (BPA-NI) standards, they provide a 0% leak-rate solution for high-volume B2B supply chains.
Technical Specifications of 202 SOT Aluminum Ends
In the global B2B beverage market, the 202 SOT is the industry standard for 330ml, 355ml, and 500ml aluminum cans. At PACKFINE, we optimize the Score Residual to a precision of ±2 microns to balance ease of opening with transport safety.
- Material: Premium 5182 Aluminum Alloy (H19 Temper).
- Pressure Resistance: Certified to handle up to 90 PSI, ideal for high-carbonation sodas and nitrogen-infused beers.
- Internal Coating: Options include Epoxy or BPANI (BPA-Non-Intent) liners to prevent metal-liquid interaction and preserve flavor profiles.
- Standardization: Compatible with B64, CDL, and ISE high-speed seaming lines.
How Material Choice Affects Product Shelf Life
“Precision in metal chemistry is the difference between a 12-month shelf life and a total inventory loss.” — Christine Wong, Senior Packaging Expert at PACKFINE.
Using the wrong alloy or a substandard lacquer leads to pinhole leaks. Aluminum’s natural oxide layer, combined with our advanced internal coatings, ensures that high-acid beverages do not corrode the container, maintaining a 100% airtight double seam.
Comparison: Aluminum SOT vs. Tinplate EOE
| Feature | 202 SOT (Aluminum) | Tinplate EOE |
|---|---|---|
| Best Use Case | Beer, Soda, Sparkling Water | Canned Vegetables, Soups |
| Pressure Limit | High (90 PSI) | Low/Medium |
| Compliance | FDA, BPANI Available | Standard Food Grade |
The Engineering Behind the “Pop”: Score Line Precision
The “Pop” and “Tear” values are critical for user experience. PACKFINE utilizes high-speed vision inspection systems to monitor every lid. By maintaining a strict Score Residual, we ensure the tab never snaps prematurely during high-temperature pasteurization or long-distance shipping in non-refrigerated containers.
Frequently Asked Questions for B2B Buyers
Q: How does PACKFINE ensure 202 SOT lids are compatible with my seaming machine?A: We provide standardized 202 B64 and CDL profiles that match global seamer settings. Our technical team offers “Double Seam” optimization guidance, measuring body hooks and end hooks to ensure a 100% hermetic seal.
Q: Are your aluminum ends BPA-free?A: Yes, we specialize in BPANI (BPA Non-Intent) coatings that meet the latest European and North American food safety regulations (SGS certified).
