Meaning
Statutory directives set authorization standards, decontamination efficiency thresholds and challenge test protocols for post-consumer resins used in food contact packaging. Compliance with recycled plastic contact rules requires recyclers to validate that super-clean recycling processes remove volatile surrogates to non-detectable levels. The framework governs post-consumer resin inclusion limits, functional barrier layer designs and input waste stream purity criteria.
It ceases to apply to industrial pallets, non-food crates or automotive components where human ingestion risks do not exist.
Decontamination Testing
Recycling technology providers prove process decontamination capability by intentionally spiking recycled flake with surrogate chemical contaminants. Applying high temperature vacuum stripping cleans the resin before final pelletization and testing. Under recycled plastic contact rules, testing laboratories analyze output pellets to confirm that residual contaminant levels fall below calculated human exposure limits.
Virgin resin bypasses these challenge tests because synthesis chemical purity is documented directly by raw material producers.
Source Control
Input waste streams must originate from food grade collection loops to limit hazardous industrial compound contamination risks.
Migration Thresholds
Finished food packaging structures must prevent chemical migration into food contents across expected shelf life durations. Adding functional barriers, such as virgin polymer skin layers in co-extruded structures, helps packaging converters meet strict regulatory standards while incorporating post-consumer content. Regulatory agencies issue explicit authorization letters defining maximum permitted blend ratios and temperature limits for end use.
Continuous batch verification ensures that food contact safety remains uncompromised.
