211# Tinplate Easy Open Lid: Sizes, Uses & Sourcing Guide
A 211# tinplate easy open lid is a 65mm-diameter can end made from tin-coated steel, featuring a pre-scored opening with a pull tab for hand-opening without a can opener. The "211" refers to the nominal can diameter code (2 11/16 inches), and it is a standard closure for many small food and beverage cans.
What sizes and materials are used for 211# tinplate easy open lids?
The 211# lid typically has a 65mm diameter and fits cans with a 211 body diameter. It is made from electrolytic tinplate, often with a lacquer lining for food contact. Coatings may be epoxy-phenolic or organosol, depending on the product's acidity and processing method.
Common tinplate thicknesses
- 0.16–0.18mm for standard food cans
- 0.18–0.20mm for carbonated or pressurized products
- Higher temper (T4–T5) for better scoreability
Which products use a 211# tinplate easy open lid?
These lids are widely used for canned fish, pet food, sauces, fruits, vegetables, and some dairy products. They are also found on small paint and chemical cans where a secure, easy-open seal is needed. The easy-open feature improves convenience for consumers and reduces the need for tools.
How do you choose the right 211# easy open lid?
Match the lid's diameter and seaming profile to your can body, and select the coating based on the product's pH and sterilization process. Consider the pull-tab design (ring or non-ring) and the required score residual for safe opening. For consistent quality, verify the supplier's tinplate grade and food-contact certifications.
If you need bulk quantities, you can order tinplate to Guangda factory in China, which supplies 211# tinplate easy open lids and other can components. Always request samples to test seaming and opening performance before full production.
