Overview

EN 15421:2021 - Packaging - Flexible aluminium tubes - Determination of the adhesion of the internal and external protective lacquering is a CEN standard that specifies a laboratory method to assess the adhesion of protective lacquers on flexible aluminium tubes. The method applies to tubes used for pharmaceutical, cosmetic, hygiene, food and other household products where internal or external lacquer integrity is critical for product safety and performance.

Key Topics

  • Scope and objective: Defines a repeatable test to detect cracks and delamination of internal and external protective lacquers on aluminium tubes.
  • Principle: A compressing device creates a standardized, sharp-edged deformation (kink) in the tube; the tube is then stretched axially and inspected visually for lacquer failure.
  • Apparatus: Two compressing device types are accepted:
    • Type 1 (uses an internal guide pin - ∅8 mm for tube diameters ≤19 mm; ∅15 mm for >19 mm).
    • Type 2 (uses an external guide ring).
  • Procedure:
    • Type 1: Compress until the tube body is reduced to (15 ± 5) % of original length.
    • Type 2: Compress until the tube body is reduced down to the guide ring.
    • After compression and re-stretching, visually check for cracks or detached lacquer; presence of either is a failure.
  • Test conditions: Standard testing at (23 ± 5) °C. For products stored/used at cold conditions, samples must be conditioned at (5 ± 3) °C for at least 2 hours and tested immediately after removal.
  • Reporting requirements: Test reports must reference EN 15421:2021 and include batch identification, sample description, lacquer nature, test temperature, number of samples, defect description, acceptance decision and testor/date/place.

Applications

  • Quality control and incoming inspection of flexible aluminium tubes used in pharmaceutical, cosmetic, food, and household packaging.
  • Production process validation of internal/external protective lacquering to prevent contamination, corrosion and preserve product shelf life.
  • Supplier qualification, failure analysis and regulatory compliance testing where lacquer adhesion is a critical performance attribute.
  • Used by packaging manufacturers, coating formulators, quality labs, regulatory bodies and R&D teams developing tube coatings.
