## Food-Grade Recycled Plastic: FDA Compliance, Safety Testing, and Packaging Applications Guide

### Regulatory Framework

**FDA Requirements (USA)**:
– 21 CFR 177: Food contact substances
– NOL (No Objection Letter): Required for PCR
– Challenge testing: Contaminant clearance
– Process description: Detailed documentation

**EU Requirements**:
– Regulation 10/2011: Plastic materials
– EFSA scientific opinion: Safety assessment
– Recycling process registration
– Quality control procedures

**China Requirements**:
– GB 4806.6: Plastic food contact
– Positive list: Approved substances
– Migration testing: Required
– Hygiene certificate: Mandatory

### Safety Testing Protocol

**Challenge Testing**:
– Surrogate contaminants: 3-5 types
– Concentration: 10-100x expected
– Processing: Full scale simulation
– Analysis: GC-MS, LC-MS detection

**Migration Testing**:
– Food simulants: 10% ethanol, 3% acetic acid
– Conditions: Time/temperature accelerated
– Limits: SML (Specific Migration Limit)
– Detection: 0.01 mg/kg sensitivity

### Applications

**Beverage Packaging**:
– PET bottles: 100% recycled content
– HDPE caps: 30-50% recycled
– Labels: Recycled film

**Food Containers**:
– PP trays: 50-100% recycled
– PS foam: Phase-out, alternatives
– Multilayer: Barrier requirements
