Delamination after the job looked fine
Delayed delamination is a bond that looked fine at the laminator and let go hours or days later. The usual causes are ink that was still soft, stock that took on moisture, or an adhesive that needed more time.
Checks
- Peel a sample the next day, not only at the end of the run. Some adhesives keep building bond for hours.
- If the film lifts and takes ink with it, the ink was not anchored. If it lifts clean, the adhesive never grabbed the surface.
- Check storage. A warm, damp pile can swell the sheet and pull a marginal bond apart.
- Leave a sealed edge where the job allows it, and avoid folding or trimming until the bond has set.
