EN 14477:2004

Overview

EN 14477:2004 (CEN) defines test methods for the determination of puncture resistance of flexible packaging material. The standard describes validated procedures to assess how well single- and multilayer flexible packaging materials resist penetration by a sharp object under controlled conditions. It is intended for use wherever puncture performance is a relevant quality attribute in packaging design, production and testing.

Key topics

• Scope and applicability - Specifies that the methods apply to flexible packaging materials, including multilayer constructions.
• Test methods - Provides standardized procedures for measuring puncture resistance using laboratory test equipment and defined test sequences.
• Sample preparation and conditioning - Describes requirements for selecting, cutting and conditioning specimens prior to testing to ensure reproducible results.
• Test apparatus and probes - Defines the need for appropriate puncture test fixtures, probes and force-measurement instrumentation (general requirements without prescribing proprietary devices).
• Test procedure and data reporting - Covers how to conduct tests, record puncture force or energy, and report results so they are comparable between laboratories.
• Interpretation and reproducibility - Addresses repeatability and reproducibility considerations to support quality control and material comparisons.

Applications

EN 14477:2004 is used across the packaging supply chain for practical purposes such as:

• Quality control in manufacturing of films, laminates and pouches to verify puncture resistance specifications.
• Material selection in product development where barrier and mechanical integrity under puncture risk are important (e.g., food, medical, industrial packaging).
• Supplier qualification and incoming inspection of flexible packaging materials.
• Comparative testing in R&D to evaluate multilayer constructions, coatings or sealants that affect puncture performance.
• Independent testing in laboratories to provide consistent, comparable puncture-resistance data for contracts and regulatory dossiers.

Who uses this standard

• Packaging manufacturers and converters
• Materials scientists and R&D teams developing flexible laminates
• Quality assurance and compliance professionals
• Independent test laboratories and certification bodies
• Procurement teams specifying performance requirements for packaging materials

Related standards

Complementary EN standards exist for other mechanical and barrier tests on flexible packaging (tensile strength, tear resistance, burst strength, permeation tests). For a complete test program, EN 14477:2004 is typically used alongside those relevant packaging test standards published by CEN.
