Glue layer 5–50 µm — seal strength.
Barrier coating 5–30 µm — shelf life.
Non-destructive thickness for batch consistency.
| Sub-scenario / Process | Film Layer | Thickness Range | Application & Metrology Value |
|---|---|---|---|
| Lamination Adhesive | Adhesive / glue layer | 5 µm – 50 µm | Measures adhesive between board/foil; affects seal strength and stiffness |
| Barrier Enhancement | Barrier coating (e.g. PVAC) | 5 µm – 30 µm | Controls moisture/O₂ barrier; determines food shelf life |
