A laminated mat almost never fails because the print wore out. It fails at the edge, and then it goes in the bin.
The cut edge is a raw sandwich
Two films around a printed sheet, sliced open at the perimeter.
Water gets in there and travels between the layers.
Sharp corners lift first
A square corner catches on a stack, a cloth or a sleeve.
A radius removes the thing that catches.
Heat is the other killer
Laminate marks and bubbles under a hot plate, permanently.
No amount of edge sealing changes that.
What to specify
Sealed or radiused edge, bonded margin beyond the print, radiused corners — or skip laminate entirely and take vinyl.
Three questions, answered in samples rather than adjectives.
