Barrier coating measurement for food and pharmaceutical packaging
  • Lamination Adhesive

    Adhesive / glue layer: 5 um - 50 um, Measures adhesive between board/foil; affects seal strength and stiffness

  • Barrier Enhancement

    Barrier coating (e.g. PVAC): 5 um - 30 um, Controls moisture/O₂ barrier; determines food shelf life

Frequently Asked Questions

Which packaging films affect seal strength and shelf life?

Lamination adhesive between board and foil is typically 5–50 µm and controls seal strength and stiffness. Barrier coatings such as PVAC at 5–30 µm set moisture and oxygen barrier performance, which determines food shelf life.

Why replace sampling inspection with 100% in-line monitoring?

Meter-by-meter sensing covers the full web so defective coating cannot ship. Sampling leaves gaps; 100% in-line monitoring is used to drive quality risk toward zero and to generate tamper-proof e-batch records for audits.

How does closed-loop thickness control cut packaging cost?

A monitor–analyze–feedback loop corrects deviations in seconds. Matching barrier thickness to the required performance avoids over-coating. Sites using this approach report material-utilization gains on the order of 5%–15%.

How does film-thickness data support food and pharma compliance?

Automated inspection writes electronic batch records that cannot be tampered with. Thickness and barrier data stay traceable for the lot, which simplifies quality audits when a shelf-life or seal-strength incident is investigated.
