Can seams
Can seam measurement for carbonated filling projects.
Define how seam checks will be made before accepting a carbonated can filling and seaming line.
The buyer, can supplier, end supplier and seamer information should define what checks are required and what measurements are acceptable. Carbonated products add pressure and foam factors, so the filler-to-seamer handoff and final seam quality need to be reviewed together.
| Can and end specification | Supplier drawings, material, size and end type. |
|---|---|
| Seamer setup | Change parts, chuck/roll tooling, seamer adjustment and operator access. |
| Inspection method | Visual checks, leak checks, destructive seam teardown or external seam measurements as required by the process. |
| Acceptance evidence | How many samples are checked, who records the result and when checks are repeated. |
Excessive foam, product on the can lip, unstable transfer, overfilled cans or delayed handoff can all interfere with a smooth seam process. A line review should include fill height, foam, lid placement, can handling and reject strategy rather than treating the seamer as a separate purchase.
Buyer questions
Questions buyers ask about this topic.
Can Lancing publish generic seam tolerances?
No. Seam tolerances should come from the can, end and seamer requirements for the actual package and tooling.
Does the filler affect seam quality?
Yes. Fill level, foam, can handling and transfer time can all affect how reliably a can reaches the seamer.
What samples are needed for a canning project?
Provide can bodies, ends, product information, target output, decoration route and any existing seam inspection requirements.
