Non-destructive seal seam inspection for PS trays

[erdal88]

Hello together,

Do you know any non-destructive seal seam inspection methodology for polystyrene-tyvek welding as specified below? (Normally we take the first 5 samples and perform peeling test(destructive) to be sure sealing is adequate.) But I would like to inspect all welded trays as non-destructive. I appreciate it if anyone could suggest some solutions.


Thanks in advance
