ISO 11607 is the international standard that defines requirements for packaging used with terminally sterilized medical devices. Split into two parts, it covers the design and materials of sterile barrier systems (Part 1) and the validation of forming, sealing, and assembly processes (Part 2), so a device stays sterile from the manufacturing line to the point of use.
What is ISO 11607?
ISO 11607 governs the packaging system that protects a device sterilized in its final pack. A terminally sterilized device is sterilized after it is sealed inside its packaging, so the package itself becomes a controlled part of the sterility assurance chain.
The standard has two parts. Part 1 sets requirements for materials, the sterile barrier system (SBS), and the wider packaging system. Part 2 sets validation requirements for the forming, sealing, and assembly processes that build it. Each part carries a 2023 amendment that adds risk management aligned with ISO 14971. The SBS is the minimum package that blocks microorganisms and allows aseptic presentation.
Why ISO 11607 Matters in Medical Device Development
If the sterile barrier fails, the device is no longer sterile, regardless of how well the sterilization cycle ran. A breached seal, a pinhole, or material that degrades on the shelf can put a non-sterile product in a clinician’s hands. That is a direct patient safety risk and a common source of recalls.
ISO 11607 is recognized by the FDA and harmonized under the EU Medical Device Regulation (EU MDR 2017/745) as EN ISO 11607, so packaging evidence is included in your design history file and technical documentation. Auditors and notified bodies expect SBS design rationale, validated sealing processes, and stability and performance data. Gaps delay 510(k) clearance and CE marking, and surface fast in MDSAP audits. Packaging is also a cost lever: an over-engineered pack wastes material, while an under-validated one triggers expensive revalidation late in the program.
How ISO 11607 Works
The standard splits the work between design (Part 1) and process validation (Part 2). A typical path looks like this:
- Define the packaging system: the sterile barrier system plus any protective packaging that shields it during distribution.
- Select and qualify materials for the chosen sterilization method (ethylene oxide, gamma, e-beam, or steam), since the method affects material choice and seal behavior.
- Demonstrate stability through real-time aging and accelerated aging studies (commonly per ASTM F1980) to support shelf-life claims.
- Demonstrate performance by simulating distribution stresses (per ASTM D4169) to confirm the SBS survives transport.
- Validate the forming, sealing, and assembly processes with IQ, OQ, and PQ, setting measurable windows for seal temperature, pressure, and dwell time.
- Confirm seal strength and seal integrity using methods such as ASTM F88 (seal strength), ASTM F1929 (dye penetration), and bubble leak testing (ASTM F2096).
- Verify aseptic presentation so a user can open the pack and remove the device without contaminating it.
Risk management runs through all of it. The 2023 amendments tie packaging decisions to ISO 14971, and the work is conducted within an ISO 13485 quality system with documented change control.
Common Challenges and Best Practices
Teams often treat packaging as an afterthought near design transfer, then scramble when aging studies have not started. Real-time aging takes the full claimed shelf life, so start it early and run accelerated aging in parallel for an interim release.
Worst-case selection trips up many submissions. Group your products and packaging into families, then justify a defensible worst-case configuration rather than testing every possible combination. Underpowered sample sizes are another frequent finding; tie them to a stated confidence and reliability target.
Keep records consistent. Settings cited in routine production (sealer parameters, sample plans, acceptance limits) must match the validated windows from your PQ. Lock re-qualification triggers a change control review, so a new material, sealer, or layout prompts a documented review rather than a silent drift.
How SJML Helps with ISO 11607
SJML supports sterile and non-sterile packaging and labeling with validation as part of its end-to-end CDMO services. That includes process validation through IQ, OQ, and PQ for forming and sealing operations, packaging design aligned with risk management under ISO 14971, and a quality framework aligned with ISO 13485. Its manufacturing footprint covers ISO Class 7 and 8 cleanrooms suited to sterile barrier work, and its QARA team can fold packaging evidence into the design history file, technical documentation, and submissions for FDA and EU MDR pathways.

Frequently Asked Questions
ISO 11607-1 covers the design aspects: requirements for packaging materials, the sterile barrier system, and the packaging system, including evidence of stability and performance. ISO 11607-2 covers process validation: the forming, sealing, and assembly operations that produce the packaging, validated through IQ, OQ, and PQ. Part 1 states what the package must achieve; Part 2 demonstrates the process that keeps it under control.
The FDA recognizes ISO 11607 as a consensus standard, so a manufacturer can declare conformity to support a 510(k) or other submission. It is not a regulation in itself, but packaging that meets ISO 11607 satisfies the design control and process validation expectations of 21 CFR Part 820 for terminally sterilized devices. Most regulators worldwide expect the same evidence.
A sterile barrier system (SBS) is the minimum packaging required to prevent microorganisms from entering and to allow the device to be presented aseptically at the point of use. Common examples include sealed pouches, lidded trays, and header bags. Protective packaging may surround the SBS to guard it during transport, but only the SBS provides the microbial barrier.
Shelf life under ISO 11607 is supported by stability testing demonstrating that the sterile barrier system and its seals remain intact throughout the claimed storage period. Manufacturers run real-time aging for the full claimed duration and accelerated aging to support earlier product release. Performance testing through simulated distribution confirms the package survives handling without losing integrity.
