Water Based Coatings That Keep a Pack inside the Fibre Stream
Water-based dispersion coatings achieve food barrier requirements while maintaining full fiber repulpability and standard mill recovery yields.
EN 13430 Material Recycling
Recovery Specification
European requirements mandate that packaging components demonstrate physical and chemical capability for conversion into secondary materials. This en 13430 material recycling standard provides the framework for assessing whether a package remains suitable for industrial reclamation systems after its primary use. Manufacturers must account for the presence of adhesives, inks, and barrier coatings that alter the melt flow or pulp quality during mechanical processing.
The regulation demands verifiable proof that a product does not impede the efficient extraction of raw material from a waste stream.
Protocol Applicability
Assessment procedures verify that sorting and separation equipment recognizes the unit as a target fraction rather than a contaminant. Evaluators check the compatibility of combined substrates by measuring how different components behave under heat or aqueous suspension. A package fails this protocol when its structural design prevents the recovery of a sufficient mass fraction to justify the economic cost of the operation.
Laboratory tests quantify the yield of usable material after the article passes through representative grinding or pulping circuits.
Verification Threshold
Certification relies upon documented data regarding the specific weight of non-recoverable materials that remain attached to the primary substrate. Compliance requires that the final output from a recycling run attains a purity level consistent with standard manufacturing inputs for new goods. Mills reject incoming shipments when the weight of hazardous additives or complex laminates exceeds established thresholds defined by the recovery process.
This standard holds that the design of the package itself dictates the feasibility of returning materials to the industrial cycle.
