Normative Standard
European harmonized packaging standards define requirements for packaging optimization through source reduction and the minimization of hazardous substances in packaging materials. As part of the essential requirements supporting European packaging and packaging waste legislation, standard en 13428 establishes a formal methodology to verify that a package uses the minimum mass and volume necessary to maintain functionality, safety, and consumer acceptance. The standard also mandates the systematic identification and minimization of noxious and hazardous substances throughout packaging manufacturing and converting.
It applies to all primary, secondary, and tertiary packaging formats across paper, corrugated board, plastic, and composite structures. The standard does not evaluate end-of-life recycling, composting, or energy recovery capabilities, which are governed by companion standards.
Source Optimization
Compliance verification requires a documented two-part assessment analyzing design optimization and chemical composition. Under standard en 13428, packaging designers must conduct a source reduction audit evaluating functional performance parameters including product protection, filling line runnability, logistics stacking strength, and hygiene requirements. Material mass cannot be reduced beyond the critical limit where package functionality fails.
Designers document minimum wall thicknesses, flute profiles, and board grammages required to prevent supply chain damage. Concurrently, manufacturers execute a hazardous substance audit, identifying raw materials and processing aids containing heavy metals or substances of very high concern. Chemical inputs must be evaluated to ensure that hazardous constituents are minimized at the source, preventing toxic emissions during eventual waste incineration or composting.
Technical Documentation
Packaging manufacturers assemble formal conformity declarations and assessment records to satisfy customer procurement policies and national regulatory audits. Packaging converters use standard en 13428 to guide lightweighting initiatives, replacing heavy solid board with optimized fluted board or high-strength virgin kraftliners without sacrificing protective performance. Sourcing teams verify supplier compliance dossiers to prove that delivered packaging satisfies European market access rules.
Auditable reduction records confirm that packaging solutions minimize material usage while maintaining commercial distribution integrity.
