Technical Note on Standard Can End Nomenclature
In global metal packaging terminology, trade dimensions like 200, 202, 307, 401 represent the nominal diameter in inches and sixteenths of an inch. For example, 202 signifies 2 inches plus 2/16ths of an inch (approx. 52.5mm). As an experienced easy open end manufacturer, we ensure exact tolerance compliance (within ±0.10mm) to avoid chuck slippage or double-seamer jams during high-speed filling operations exceeding 1,500 cans per minute.
Beverage Can Ends & Food Can Ends Categorization
Discover our specialized range of beverage can lids, food can ends, stay-on tabs, and peel-off foil mechanisms designed for optimal consumer convenience and seal security.
SOT Can Ends (Stay-On Tab)
Stay-On Tab (SOT) lids are the global standard for carbonated soft drinks, beer, and sparkling waters. The tab remains permanently attached to the can body after opening, eliminating environmental litter while ensuring smooth pourability.
- 200 SOT Can End: Engineered for slim and sleek aluminum cans, maximizing shelf aesthetic.
- 202 SOT Can End: The world's most utilized beverage end size for standard 335ml, 355ml, and 500ml cans.
- Pressure Resistance: Capable of withstanding internal buckle pressures exceeding 620 kPa (90 psi).
RPT Can Ends (Ring Pull Tab)
Ring Pull Tab (RPT) can ends allow the entire tear strip to detach completely from the top opening. Highly favored for non-carbonated beverages, juices, ready-to-drink coffee, and specialized liquid food items.
- 200 RPT Can End & 202 RPT Can End: Provides a wider aperture for easy liquid dispensing.

- Custom Embossing: Foil membrane can be custom embossed or printed with brand logos.
Seaming Profiles, Lining Compounds & Quality Parameters
Achieving a hermetic, leak-proof double seam requires precise alignment between the can end curl profile, seamer chuck geometry, and internal sealant distribution.
Seaming Profile Integrity
Our aluminum can lids and tin can lids are designed with optimized countersink depth and outer curl radii (CDL and B64 options) to fit standard Angelus, Ferrum, and CODMAC double seamers.
Key Seam Metrics: Overlap length, Cover Hook, Body Hook, and Seam Thickness are continuously monitored via optical seam analyzers.
Liquid Compound Lining
Every easy open end features a automated water-based or solvent-based rubber lining compound injected into the curl channel to guarantee a 100% airtight seal against micro-leakage.
Option Availability: High-temp retort compounds, PVC-free linings, and organosol gaskets formulated for aggressive acidic contents.
Score Line Residual Control
The score line depth is engineered down to micron precision. This ensures low pop-and-tear opening forces while maintaining high structural resistance to transportation shock and drops.
Tested via automatic burst pressure testers and micro-sectioning score measurement gauges.
High-Tech Customization: Printed, Embossed & QR Code Can Ends
Transform standard easy open can lids into interactive digital marketing assets and high-end brand differentiators with advanced decorative and smart manufacturing techniques.
Printed Can Ends
High-resolution offset lithographic printing applied directly to the metal surface. Color-matched tab anodizing and top-lid graphics elevate brand identity on retail shelves.
