Why Clean Packaging Foam Matters for Single-Use System Transport
Single-use systems (SUS)—including filter assemblies, tubing, and complex manifolds—are essential in biopharmaceutical, cell therapy, and gene therapy manufacturing. They streamline production, improve sterility assurance, and reduce cross-contamination risks.
However, safely transporting and unpacking these assemblies into ISO Class 5–8 GMP cleanroom environments presents unique challenges:
- Sharp components: Connectors and filter housings can pierce sterile barrier bags, leading to leaks and sterility breaches.
- Heavy parts under stress: Large or weighted manifolds can shift in transit, straining packaging and causing tears.
- Mechanical shock: Drops or vibration during shipment can damage components and compromise performance.
- Particulate release on unpacking: Packaging foams must meet ISO 5 cleanroom particle requirements (<3,520 particles/m³ ≥0.5 µm) to prevent contamination in Grade A/B suites.
- Chemical compatibility: Packaging must resist gamma sterilization (25–40 kGy) without degrading, releasing fibers, or generating extractables such as NVR, chloride, nitrate, or sulfate.
Without adequate packaging protection, filter assemblies and manifolds risk sterility failures, product loss, and non-compliance with USP <797>, USP <800>, and EU GMP Annex 1.
Key Requirements for Single-Use System Packaging Foam
To ensure integrity during transport and unpacking, protective foam should provide:
- Ultra-low particle shedding – Tested to IEST-RP-CC004.3 to safeguard cleanroom classifications (ISO 5–8).
- Gamma sterilization stability – Maintains structural integrity, cushioning, and cleanliness after 25–40 kGy irradiation (per ISO 11137).
- Low extractables and anions – Prevents chloride, nitrate, sulfate, or other residues that could compromise drug safety or cause corrosion.
- Mechanical shock absorption – Cushions heavy, delicate, or sharp components against damage during shipping and handling.
- Custom fit – Precision-cut foam that immobilizes assemblies, preventing movement and bag punctures.
- ISO 5 cleanroom packaging – Ensures foams are washed and packaged to ISO 14644-1 Class 5 and ISO 11607 standards to eliminate contamination transfer during critical cleanroom introduction.
Foamtec’s Ultra Clean Foam: A Validated Solution
| Before | After |
 |
 |
Foamtec’s Ultra Clean Foam Packaging is engineered for the highest standards of GMP manufacturing. Two validated formulations meet diverse requirements:
CleanWIPE® – 2 lb/ft³ Density for Lightweight Assemblies
- Particle Control: 52 particles/cm² ≥0.5 µm after gamma sterilization (Pass, well below 800 spec).
- Residue Control: NVR in DI water <100 µg/g (Pass), chloride/nitrate/sulfate well below USP <797> limits.
- Integrity: Retains flexibility and cushioning for tubing and small filter assemblies.
- Benefit: Prevents punctures while enabling safe unpacking in ISO 5 Grade A/B environments.
FirmWIPE® – 5 lb/ft³ Density for Heavier Manifolds
- Particle Reduction: 172 particles/cm² pre-sterilization reduced to 90 post-sterilization (−47.7%).
- Residue Control: Ultra-low NVR (77 µg/g post-sterilization) and negligible anion levels.
- Mechanical Protection: Dense foam structure absorbs shocks and supports heavy or sharp-edged components.
- Benefit: Eliminates bag punctures and protects sterile barrier integrity during transit and handling.
Both foams are manufactured, washed, and packaged in ISO Class 5 cleanrooms, ensuring the lowest possible particle and fiber release during unpacking in critical GMP areas.
