GB 4806 Testing against the EU Plastics Regulation Limits
Testing plastic food contact articles under China GB 4806 and EU Regulation 10/2011 requires harmonizing simulant choices, thresholds, and batch trace files.
GB 4806 6 2023
Meaning
Mandatory national standards established by Chinese regulatory authorities define positive monomer lists, usage restrictions and migration testing protocols for food contact plastics. Compliance with gb 4806 6 2023 dictates which synthetic resin grades may be legally imported, processed or sold within the Chinese market. Polymer producers consult these regulatory tables to verify legal additive allowances for food packaging formulations.
The standard governs raw plastic resin polymers, stopping short of regulating finalized article manufacturing tolerances.
Resinous Scope
Positive lists published within the standard categorize permitted polymer families and comonomer blend proportions. Formulating resin to align with gb 4806 6 2023 requires verifying that every base polymer and copolymer component appears in approved schedules. Unlisted synthetic polymers remain strictly prohibited from direct food contact applications regardless of overall purity level.
Material suppliers provide official conformity declarations to confirm raw resin registration status.
Migration Limit
Overall migration limits set boundaries on total non-volatile substance transfer from plastic into food simulants. Testing compliance under gb 4806 6 2023 demands exposing polymer specimens to specific solvent media, thermal conditions and exposure durations. Specific migration limits apply to residual monomers like acrylonitrile and vinyl chloride.
Industrial moulders must ensure process additives do not elevate overall migration values.
Compliance Verification
Analytical testing labs verify compliance. Official certificates confirm product legal status.
