How to Verify Food Safety Compliance of PET Sticker Films
In the world of food packaging, visual appeal is crucial—but never at the cost of safety. Labels, stickers, and decorative seals must comply with stringent safety regulations. If you're using PET food packaging label or food-safe PET sticker film, how do you know it's truly compliant? This article walks through the steps to verify the food safety of PET materials used in packaging and labeling.
Why Compliance Verification Matters
- Food contamination through chemical migration
- Product recalls and brand damage
- Regulatory fines and legal action
- Loss of market access in the EU, U.S., or Asia
For packaging converters, using holographic PET pouch film without verification can lead to devastating consequences.
Step 1: Request Compliance Documentation
- Declaration of Compliance (DoC) confirming FDA 21 CFR or EU 10/2011 status
- Migration Test Reports from accredited labs
- MSDS (Material Safety Data Sheets) showing non-toxicity
- Adhesive and Ink Certification when pre-laminated or printed
If any component (film, ink, glue) lacks food-grade validation, the label fails compliance.
Step 2: Understand Acceptable Migration Limits
Under EU 10/2011, PET-based films must remain below:
- Overall Migration Limit (OML): 10 mg/dm²
- Specific Migration Limits (SML): For substances like antimony or acetaldehyde
FDA standards require similar migration evaluations based on contact type (aqueous, fatty, acidic) and use conditions (microwave, hot fill, frozen).
Step 3: Examine Manufacturing Conditions
- Operate under GMP (Good Manufacturing Practice)
- Maintain traceability of materials
- Conduct batch-level migration testing
- Hold ISO 22000 or BRC Packaging certifications
Avoid unbranded or unverified holographic materials that may fail testing under EU, FDA, or Chinese GB standards.
Step 4: Confirm Application Scope
| Application | Confirm For |
|---|
| Outer packaging label | Indirect contact approval |
| Inner pouch layer | Direct contact approval required |
| Hot-fill or microwave | High-temp migration tested film |
| Frozen storage | Cold-resistant bonding adhesive |
Final Tip: Audit Your Supply Chain
- Work with converters who offer traceable, certified PET products
- Periodically re-test imported batches for migration
- Validate all decorative or holographic PET pouch film used in primary food packaging
