When a major pharmaceutical company had 500,000 sterile blister packs recalled last year due to non-compliant sealing, the $2.3M loss could have been prevented with one thorough pre-production review. For medical device and drug manufacturers, FDA approval isn't just paperwork—it's a critical safeguard. Use this actionable checklist to ensure your medical-grade blister packaging meets every requirement.
1. Material Compliance: Start with the Basics
- USP Class VI certification for plastics contacting drugs (essential for PVC-free blister foils)
- 21 CFR 177.1630 approval for PETG/PVC in direct food/drug contact
- Documented resin history proving no recycled content in primary blister packaging
Red Flag: Using non-approved colorants that migrate into drug products
2. Critical Seal Integrity Tests
Your blister sealing films must pass:
- ASTM D3078 bubble leak testing (≤0.5mL/min leakage rate)
-ISO 11607 validation for sterile barrier systems
- Peel strength verification (minimum 1N/15mm for child-resistant blisters)
3. Labeling Pitfalls That Trigger Rejections
- Missing "Rx Only" markings on prescription drug blisters
- Incorrect NDC number formatting (must match FDA database)
- Non-compliant Braille requirements for Schedule II-V drugs
Pro Tip: RFID-enabled blister cards help automate tracking compliance
4. Stability & Aging Validation
- 40°C/75% RH accelerated aging tests for 90-day equivalent
- Photostability reports if using clear blister packaging for light-sensitive drugs
- Extractables/leachables data for novel high-barrier blister materials
5. Submission-Ready Documentation
Ensure your blister packaging manufacturer provides:
- DMF Type III references for materials
- Process validation reports (IQ/OQ/PQ)
- Full migration study results
Non-compliance costs more than just FDA rejection—it erodes patient trust. Partner with ISO 13485-certified blister suppliers who speak FDA's language fluently.
