Meaning
Analytical protocols define this regulatory framework to quantify mass transfer from packaging materials into food stimulants. En 13130 migration governs the testing of plastics intended for contact with foodstuffs by setting concentration limits for individual chemical substances. Specific analytical conditions ensure that potential health hazards remain below safety thresholds during the intended lifespan of a container.
Regulatory Compliance
Producers utilize these procedures to generate data for declaration of compliance documents. The standard mandates extraction tests in solvents that replicate fat or water based food chemistry. Accuracy depends on the calibration of instruments such as gas chromatographs to detect trace residues at the parts per billion range.
Failures occur when internal additive levels exceed the set specific migration limit due to poor manufacturing controls.
Process Variable
Melt temperature and residence time influence the degree of molecule diffusion through the polymer matrix. High thermal exposure during injection moulding degrades stabilizer components and increases the likelihood of leachables forming inside a finished part. Regrind usage requires strict monitoring because degraded chains allow faster mobility of chemical compounds compared to virgin resin structures.
Laboratory results from a thin plaque do not guarantee that a thick wall geometry will pass the same assessment under identical food stimulant exposure.
Economic Consequence
Failure to meet these criteria forces a full recall or the destruction of inventory to avoid legal liabilities. Excessive testing cycles add cost to every design iteration when initial material selection does not account for total additive chemistry. Careful formulation selection allows for compliance while maintaining the structural performance required for high pressure or high temperature applications.
Standardised testing remains a mandatory overhead for any plastic packaging supplier operating within regulated markets.
