THE CRITICAL GUIDE TO CAN & LID SPECS
 
 

Why submitting can samples matters

You switch lids unknowingly and suddenly product is leaking and seams are failing. The root cause? An end that’s just 0.002" different. It’s thinner than a sheet of paper but big enough to ruin a batch. These tiny folds of aluminum are your product’s last line of defense, and they’re measured in thousandths of an inch. When your seams are off by even a fraction, it can mean shelf instability, leakage, recalls and reputation damage.

Sending can samples for setting up your seamer is a critical precision step that ensures your seamer is set up to match your exact can and lid specifications. Just because a lid says “202 B64” doesn’t mean they’re all the same - they’re not.

CHECK IT OUT

3D scans of widely used B64 lids show variances across manufacturers. Each have proprietary product specifications, and every body/end combo can require unique setup and tooling.

WHY IT MATTERS

Every manufacturer - Ball, Crown & Ardagh included - have minor but meaningful variances in their can and lid dimensions. That variability is a seam failure waiting to happen.

Here's how you can protect your seams

SUBMIT YOUR SPECS

  • Submit Specs: Upload technical docs to help us verify fit and compatibility with your seamer.
  • Send Can Samples: Send the exact cans and lids you'll be using. This lets us dial in your seamer tooling precisely.

KNOW YOUR SOURCE

  • Know Your Source: Buy from a trusted, consistent supplier. If you’re not sure where your ends are coming from, ask.
  • Single-Source: Whenever you can, source cans and ends from the same manufacturer.

*FOR NEW EQUIPMENT PURCHASES
 
 

To ensure your equipment is production-ready and runs smoothly, Cask cannot commit to a confirmed lead time until Can & Lid samples are received. Some formats may require custom parts or seam tooling, which can take additional time to source.
