Barrier coating measurement for food and pharmaceutical packaging — adhesives and barrier films.

Focus Areas

Key process windows

Glue layer 5–50 µm — seal strength.

Barrier coating 5–30 µm — shelf life.

Non-destructive thickness for batch consistency.

Metrology Table

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

Lamination Adhesive

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
