ISO 11607 Packaging Validation

ISO 11607 addresses packaging for terminally sterilized medical devices, including both the sterile barrier system itself and validation of the processes used to form, seal, and assemble it. For manufacturers, this creates two related questions: does the packaging system protect the device and maintain the sterile barrier, and can the packaging process consistently produce that result?

A robust validation program needs to answer both. Pathway supports the development and execution of medical device packaging validation programs, including testing of package integrity, seal performance, aging, distribution, and the packaging process itself.

This becomes particularly important during design verification and commercialization because the process being validated needs to reflect the manufacturing conditions that will actually be used.

Seal Strength and Package Integrity Testing

A package may look acceptable without actually providing adequate evidence of performance. Validation therefore depends on objective testing.

Pathway’s packaging testing capabilities include ASTM F88 seal strength testing, which evaluates the force required to separate sealed package materials. Seal strength data can help evaluate whether a sealing process is producing repeatable package performance and can be used alongside other testing when establishing appropriate sealing parameters.

Pathway also supports ASTM F1929 dye penetration testing, used to evaluate certain package seals for channels or other seal defects. For packages requiring burst or pressure testing, Pathway supports testing associated with ASTM F1140 and ASTM F2054. These methods provide additional ways to evaluate package integrity and seal behavior under pressure.

The appropriate test strategy depends on the packaging configuration and the requirements of the program. The important point is that packaging performance has to be demonstrated through evidence, not visual appearance alone.

Accelerated Aging and Real-Time Aging

Shelf life is another major component of a medical device packaging program. A package that performs correctly immediately after manufacturing still has to maintain the required characteristics over the period in which the finished device may be stored.

Pathway supports accelerated aging and real-time aging, including accelerated aging work associated with ASTM F1980. Accelerated aging allows companies to evaluate package performance after simulated aging conditions while real-time aging continues in parallel. Packaging can then be evaluated after aging to determine whether the system continues to meet defined requirements.

Shelf-life planning becomes especially important when companies are preparing for verification, regulatory submissions, or commercial launch because aging studies introduce real calendar time into a development program. Waiting until the end of development to think about packaging and shelf life can create unnecessary scheduling pressure. Incorporating them into the manufacturing and validation plan earlier creates a clearer path toward commercialization.

Distribution Simulation

A medical device package does not remain stationary after it leaves production. Finished product may experience shipping, vibration, handling, compression, and other transportation conditions before reaching the point of use. Packaging therefore has to be evaluated with distribution in mind.

Pathway supports distribution simulation using ISTA protocols as part of packaging validation. Distribution testing can be combined with subsequent packaging evaluation so teams can understand whether transportation conditions have affected package integrity or performance.

This connects another part of commercialization back to packaging design. Package dimensions, internal support, device movement, sterile barrier materials, and the overall packaging configuration can all influence how the product performs during distribution.

Sterilization Compatibility and Coordination

Packaging and sterilization should not be developed independently. Packaging materials and configurations need to be considered in relation to the intended sterilization method, and finished packaging must continue to perform after sterilization.

Pathway supports packaging programs involving ethylene oxide, gamma, and electron-beam sterilization, including packaging-material compatibility evaluation and sterilization coordination. Pathway also has access to a validated two-pallet EO family cycle through STERIS in Temecula that has been used across multiple customer programs.

For emerging medtech companies, having manufacturing, packaging, and sterilization coordination connected within the same broader program can remove a significant amount of vendor management. Instead of treating sterilization as an isolated event after packaging is complete, the sterilization strategy can be considered as packaging and manufacturing decisions are made.

Packaging Process Validation: IQ, OQ, and PQ

Designing an appropriate sterile barrier system is only part of the work. The manufacturing process used to create that package also has to be controlled.

Pathway supports packaging process validation through Installation Qualification, Operational Qualification, and Performance Qualification, commonly referred to as IQ, OQ, and PQ. IQ confirms that packaging equipment and associated setup have been installed appropriately and meet defined specifications. OQ evaluates the process across defined operating ranges and helps establish parameters under which the equipment can repeatedly produce acceptable packaging. For sealing processes, variables such as time, temperature, and pressure may need to be evaluated and controlled.

PQ demonstrates that the packaging process can perform consistently under actual production conditions. Pathway’s packaging process validation capabilities also include worst-case seal parameter testing and process capability studies to evaluate repeatability.

The result is not simply a package that passed a test once. The objective is a packaging process capable of repeatedly producing acceptable output during manufacturing.

Packaging for Design Verification and Clinical Builds

One of the most important transitions in a medical device program occurs when engineering prototypes give way to design verification units. The question changes from “Can we build it?” to “Can we build it in a controlled and repeatable way that represents the product moving toward commercialization?”

Packaging becomes part of that transition. Pathway supports design verification and clinical builds alongside manufacturing, cleanroom assembly, packaging, validation, quality, and regulatory activities. Packaging requirements can therefore be developed within the larger manufacturing program rather than being added after the device has already moved through verification.

For emerging device companies, this can be particularly valuable when the existing manufacturing process still depends heavily on engineering knowledge, prototype vendors, or manual operations that have not yet been formalized for production. The same principle applies to packaging. A package used to transport prototypes between engineering teams is not necessarily the sterile barrier system or production process required for a commercial medical device.

Clinical production introduces another set of operational requirements. Devices need to be manufactured, handled, packaged, documented, and processed in a controlled manner consistent with the requirements of the program. Pathway’s ISO 13485 manufacturing environment allows packaging to remain closely connected to the clinical manufacturing operation, including work performed within its ISO Class 7 cleanroom.

Labeling, Traceability, and Design Controls

Packaging does not stop at the sterile barrier. Finished medical devices also require labeling and traceability appropriate to their regulatory and commercial requirements.

Pathway’s packaging capabilities include support for Unique Device Identifier implementation and verification, FDA labeling requirements, EU MDR labeling requirements, barcode durability and scannability testing, and integration of labeling into packaging validation activities.

A technically successful package is also not enough if the work supporting it cannot be documented. Packaging requirements should connect back to the device’s design inputs, risk analysis, verification and validation work, process controls, and manufacturing records.

Pathway supports integration of packaging activities into design controls, including defining packaging-related requirements, evaluating risks, developing verification and validation protocols, and maintaining traceability for regulatory documentation. Packaging validation results can support the documentation required as companies prepare for regulatory submissions including 510(k), De Novo, or PMA pathways.

Cleanroom Packaging and Assembly Under One Manufacturing Program

For devices requiring controlled-environment manufacturing, separating assembly and packaging across multiple suppliers can introduce additional handling, scheduling, documentation, and logistics.

Pathway supports both medical device assembly and packaging within its ISO 13485 manufacturing operation, including approximately 1,600 square feet of ISO Class 7 cleanroom space. That creates the ability to manage more of the product flow within one manufacturing organization, from component and subassembly work through cleanroom assembly, packaging, sterilization coordination, and production support.

For companies moving from development into recurring manufacturing, reducing unnecessary handoffs can make the overall production process easier to control.

From Manual Packaging to Scalable Production

Early commercial production rarely looks exactly like mature commercial manufacturing. A company preparing its first verification units, clinical builds, or commercial lots may not need a highly automated packaging operation. The immediate priority is typically establishing the process, understanding its critical variables, documenting it, validating it, and proving that it can be repeated.

As volumes increase, the economics begin to change. Pathway’s broader manufacturing model allows programs to progress from manual operations into semi-automated and more highly automated processes where the production requirements justify it.

Pathway has developed custom manufacturing equipment, heat-sealing systems, test fixtures, vision inspection systems, leak-testing equipment, coating systems, and other process-specific automation for medical device manufacturing programs. This allows packaging and manufacturing processes to evolve rather than forcing a company to build its final high-volume production system before the commercial demand exists.

The process can be established first. Automation can follow where it creates a measurable benefit.

One Program From Packaging Development to Commercial Production

Medical device companies often reach a point where packaging, manufacturing, sterilization, regulatory documentation, supply chain, and validation all begin moving at the same time. Managing each through a separate organization can work, but it creates more interfaces for the internal team to coordinate.

Pathway’s model brings many of those activities into a single medical device manufacturing program. That can include sterile barrier system development, pouch sealing, thermoformed tray development and sealing, backer card prototyping, packaging material and sterilization compatibility evaluation, cleanroom assembly and packaging, ISO 11607 packaging validation, ASTM seal and package integrity testing, accelerated and real-time aging, distribution simulation, post-sterilization package testing, IQ/OQ/PQ, worst-case process evaluation, process capability studies, labeling and traceability support, EO/gamma/e-beam sterilization coordination, design verification and clinical builds, quality and regulatory support, supply chain coordination, and commercial production support.

Those capabilities allow the packaging process to remain connected to the device as it progresses through development and into manufacturing.

Medical Device Packaging Is a Commercialization Decision

The best time to discover a packaging problem is not immediately before a regulatory submission or commercial launch.

Packaging affects sterilization, validation, shelf life, distribution, manufacturing, labeling, quality documentation, and the eventual production process. Treating it as part of commercialization earlier gives engineering and operations teams more room to develop a packaging system that can actually move with the product.

For Pathway, that is the larger role packaging plays. We are not only packaging a finished device after development has ended. We support the transition from development into controlled manufacturing, helping establish the sterile barrier system, validate the packaging process, coordinate sterilization, complete required testing, and continue supporting the product as production grows.
