METALLIZED FILM: COMPARE BARRIER DATA AND FINISHED-PACKAGE PERFORMANCE Editable planning/verification record — Yenra Updated: October 2, 2026 Article: https://yenra.com/metallized-film/ Purpose: Compare oxygen and moisture transmission data on a common basis and identify what must be tested after converting and sealing. Intended reader: Flexible-packaging engineers and buyers comparing film structures HOW TO USE Save a working copy. Enter the actual specification, units, assumptions and evidence references in each field. Preserve original observations and record changes. Have the responsible reviewer resolve missing or conflicting requirements before release. Examples below are fictional teaching inputs, not process settings or acceptance standards. RECORD 1.

Finished-package transmission, integrity tests and product trial results: ____________________________________________________________ 9. Comparison gaps, retest request and release criteria: ____________________________________________________________ WORKED EXAMPLE AND LIMITS FICTIONAL: Film OTR is 0.50 cm3/(m2 day) under specified test conditions. Uniform exposed area is 0.080 m2. Estimated contribution through that film area is 0.50 x 0.080 = 0.040 cm3/day at those same conditions. This simplified estimate excludes seams, closures, damage and changing conditions; it is not a measured whole-package rate or a shelf-life prediction.
