The Most Common Pitfalls in Medical Device Packaging (And How to Avoid Them)

What are the hidden costs of medical device packaging mistakes?

Beyond regulatory fines, poor packaging can cause product launch delays, slowdowns in product release, and damage to customer trust. Even a minor oversight in validation, labeling, or material selection can have a ripple effect throughout the entire supply chain.

This article reveals the top packaging pitfalls, explains the medical device packaging requirements you need to meet, and highlights strategies to protect both your business and patients. Read on to learn how to safeguard your devices from failure.

What Are Medical Device Packaging Failures?

A medical device packaging failure occurs when the packaging does not maintain integrity throughout its lifecycle. This includes everything from manufacturing and sterilization methods to storage, shipping, handling, and use. Failures can result in:

• Breaches of sterile barrier systems
• Weaknesses in primary packaging such as pouches, trays, or barrier films
• Crushed or compromised secondary packaging like cartons or a cardboard box
• Damaged tertiary packaging during distribution

Ultimately, failures put patient safety at risk and erode customer satisfaction. They also force packaging complaint investigation, root cause analysis, and costly remediation efforts. What begins as a technical problem quickly becomes a business and regulatory issue.

Examples of Packaging Failures

• Seal Strength Failures
  One of the most frequent issues involves weak seals. During routine ASTM F88 testing, packages may show inadequate seal strength, leaving gaps that compromise barrier properties. A failed seal exposes the sterile medical device to microbial ingress, leading to recalls, damaged trust, and potential harm to patient safety.

• Material Degradation Under Sterilization
  Packaging must be compatible with the chosen sterilization process. For example, barrier films may lose flexibility when exposed to ethylene oxide, steam, or gamma radiation. If not addressed, the consequence is often a sterile barrier that splits open months later, long after the device has shipped. The FDA also points manufacturers to these consensus standards when documenting sterilization development, validation, and routine control.

• Labeling and Identification Errors
  FDA requires most device labels and packages to bear Unique Device Identification (UDI) and be listed in the GUDID database; the EU MDR likewise mandates UDI-DI/UDI-PI for traceability. A mislabeled carton or a missing UDI can trigger mix-ups, compliance issues, and safety risks.

• Distribution-Related Damage
  Even when sterile barriers are intact, improper protective packaging or overlooked distribution simulation testing can lead to crushed cardboard box shippers, punctured trays, or compromised tertiary packaging. Such damage results in packaging test failures and costly packaging complaint investigations.

• Inadequate Package Integrity Testing
  Skipping Integrity Tests, such as dye penetration, bubble emissions, or microbial ingress checks, creates blind spots. Without thorough package integrity verification, a sterile barrier system may appear functional but actually fail during storage, shipping, or use.

• Subpar Barrier Protection Against Microbes
  The microbial barrier is the most critical function of sterile packaging. If improper packaging design weakens barrier protection, the sterile device may be exposed to contamination long before reaching the end user. ISO 11607-1 explicitly links materials, sterile barrier systems, and packaging systems to maintaining sterility to the point of use—so barrier selection and process controls must be evidence-based and validated, not assumed.

The Most Common Medical Device Packaging Mistakes

What begins as a small error—such as poor material selection or weak seals—can snowball into:

• Regulatory affairs delays due to noncompliance with ISO 11607 or ISO 13485:2016
• Product launch delays caused by re-validation and re-testing
• Slowdowns in product release due to investigations into failed lots
• Medical device recalls when non-sterile devices reach the market
• Loss of customer confidence and long-term harm to brand reputation.

For manufacturers, the lesson is clear: packaging is not just a box or pouch. It is a critical system that demands careful design, rigorous testing methods, and full alignment with regulatory standards.

The Most Common Medical Device Packaging Mistakes

Now that we’ve explored how packaging failures occur, let’s examine the underlying mistakes that lead to them. Many of these errors stem from overlooked details in the packaging design process, a lack of compliance with standards and medical frameworks, or shortcuts in validation and testing. Understanding these pitfalls is key to building packaging systems that are not only compliant but also paramount to safety and aligned with business needs. 

1. Ignoring Packaging in the Design Phase

In high-risk industries like medical devices, even a very low failure rate is often considered unacceptable. 

Too often, teams focus on device innovation while postponing packaging decisions until later stages. This leads to unnecessary time for revisions, increased lead times, and higher costs when validation failures force redesigns.

• Example: A new surgical instrument is finalized before packaging engineers are consulted. Once testing begins, the trays fail Burst Test evaluations, forcing the team back into redesign—delaying market release by months. That’s not just a delay. That’s millions lost.

2. Improper Packaging and Weak Barrier Protection

Improper packaging design is one of the leading causes of packaging failure rates. In one review of packaging failure modes, 36 out of 60 observed failure types (i.e. 60%) were related to pouch defects (holes, seal defects, delamination) in recalled devices. 

Weak seals, poor barrier films, or inconsistent seal strength undermine sterile barrier systems and increase the risk of ingress. 

• Protective packaging decisions must factor in barrier protection, tensile strength, and distribution stresses.
• Failing to validate primary packaging, secondary packaging, and tertiary packaging together can create gaps that compromise patient safety.

3. Overlooking Validation of Packaging Processes

Skipping or cutting corners on installation qualification (IQ), operational qualification (OQ), and performance qualification (PQ) is a costly mistake. These steps are essential categories of package validation and must be documented in a validation report.

• Without full IQ/OQ/PQ evidence, regulatory authorities may reject or flag packaging systems as nonconforming, delaying product approval.
• Regulatory agencies may reject packaging if validation of packaging processes is incomplete, leading to product launch delays and slowdowns in product release.

4. Neglecting Compatibility with Sterilization Methods

Packaging must withstand the rigors of sterilization methods such as ethylene oxide, gamma, or steam. Weak raw materials or incorrect manufacturing methods can result in compromised sterile barriers.

• Under ISO 11607-1, stability (i.e. shelf-life) testing must use real-time aging (which can take five years or more) but may initially rely on accelerated aging models (e.g. ASTM F1980) to infer long-term integrity.
• If packaging materials are not compatible, sterilization may cause embrittlement, delamination, cracking, or loss of seal strength. These defects may not manifest until later in shelf life or after distribution.

5. Weak Labeling and Identification Systems

Errors in package labeling, Automatic identification, or Unique Device Identification (UDI) aren’t just administrative lapses — they’re traceability failures. Inadequate user labeling or missing user instructional information can confuse the prospective user, disrupt hospital inventory systems, and lead to misuse or delayed care.

The FDA’s UDI Final Rule and the EU MDR both demand that each device carry a traceable identifier linked to a centralized database entry. A missing or mismatched identifier can trigger an immediate field correction or recall. 

It’s also common for labeling artwork or barcodes to be created late in the design phase, often after packaging validation. This sequencing is risky; when label materials or printing methods differ from validated conditions, ink adhesion, print legibility, or seal interference can all jeopardize compliance. Integrating labeling design early within the packaging validation process avoids last-minute rework and regulatory holds.

6. Skipping or Shortening Testing Methods

Testing is where many mistakes surface—and where shortcuts cause the greatest damage. Requirements for testing include primary tests, Integrity Tests, and Strength Tests. Beyond these, manufacturers must also perform distribution testing, distribution simulation testing, and additional testing such as tensile strength or visual inspection (ASTM F1886).

• Overlooking package validation testing is a common mistake. Even packaging that passes initial tests may fail under real-world shipping and handling.
• Skipping tests not only increases the risk of noncompliance but also sets the stage for medical device recalls.

7. Mismanaging Packaging Materials and Traceability

The wrong material selection or failure to use traceable materials introduces avoidable risks. Many companies make the mistake of substituting suppliers without revalidating packaging, assuming previously-validated packaging materials will remain compliant.

• Such substitutions often fail performance standard checks.
• Proper traceability ensures full compliance with quality management system requirements such as ISO 13485:2016 and ISO 9001:2015.

8. Underestimating Supply Chain and Distribution Requirements

Packaging is often validated under ideal conditions but fails to account for the realities of the supply chain. Long-distance transport, temperature fluctuations, and handling stress all create risks.

• Skipping distribution requirements testing can result in crushed cartons, damaged trays, or compromised sterile barriers.
• These issues cause packaging complaint investigations, root cause analysis, and unnecessary delays.

Each of these mistakes—whether in design, validation, sterilization, labeling, or testing—leads to increased packaging complaint investigations, recalls, and lost business opportunities. In the next section, we’ll explore the medical device packaging requirements you must meet to ensure compliance, protect patients, and achieve successful product development efforts without costly setbacks.

Medical Device Packaging Requirements

Meeting medical device packaging requirements is not optional—it is the foundation of patient safety, regulatory compliance, and market success. These requirements establish the framework for how packaging must be designed, tested, validated, and monitored throughout the entire product development process.

When manufacturers cut corners or overlook these standards, the consequences can be severe: medical device recalls, slowdowns in product release, or even harm to public health. Below, we outline the essential requirements every medical device manufacturer must address.

1. Standards and Regulatory Requirements

Medical device packaging is governed by strict frameworks:

• ISO 11607-1 and ISO 11607-2 outline the basic standards for sterile barrier systems.
• ISO 13485:2016 and ISO 9001:2015 define requirements for a quality management system (QMS).
• Regulatory affairs teams ensure compliance with FDA and EU MDR requirements for labeling, package integrity, and distribution requirements.

Noncompliance doesn’t just slow you down—it can shut you out of markets entirely.

2. Validation of Packaging Processes

Validation requires multiple stages:

• Installation Qualification (IQ): Ensures equipment is installed properly.
• Operational Qualification (OQ): Verifies packaging machines perform within specified limits.
• Performance Qualification (PQ): Confirms packaging maintains integrity under simulated conditions.

Each of these stages must be documented in a validation report and linked to the control of activities defined within the Quality Management System (QMS). Every skipped step today becomes a failure point tomorrow.

3. Testing Methods and Package Validation Testing

Testing is at the heart of packaging compliance. Requirements for testing go far beyond basic inspections and must include a wide spectrum of package validation testing:

• Integrity Tests: Detect leaks or seal failures.
• Strength Tests: Evaluate tensile strength and seal strength.
• Distribution Testing: Simulates transportation stresses.
• Comprehensive packaging validation: Incorporates microbial barrier testing, sterile barrier verification, and visual inspection.

4. Material Selection and Traceability

Material selection plays a critical role in sterile barrier success. Packaging must withstand sterilization, distribution, and long-term storage without compromising performance.

• Using traceable materials ensures that every component of the packaging system can be linked back to verified suppliers and processes.
• Substituting non-validated or previously validated packaging materials without proper revalidation often causes packaging test failures.
• Materials must provide barrier properties, barrier protection, and microbial barrier functions while maintaining durability.

Manufacturers must document these choices in their quality management system, ensuring transparency and compliance during audits or inspections.

4. Labeling and Identification

Correct and compliant labeling is essential to patient safety and regulatory approval.

• Unique Device Identification (UDI): Provides traceability across the product lifecycle.
• Automatic identification: Helps streamline scanning and inventory control in hospitals.
• User labeling & user instructional guides: Provide essential directions for the prospective user.
• Package labeling: Must meet strict requirements for labeling, including languages, warnings, and instructions per regulatory region.

Failure here can result in quality events, regulatory affairs delays, and serious risks for patients in clinical environments.

6. Alignment with Manufacturing Methods and Quality Systems

Packaging is only as strong as the processes that create it. Manufacturers must align manufacturing methods with QMS oversight, ensuring:

• Subsequent inspection verifies package quality after production runs.
• Detection of design flaws is addressed early through cross-functional kinds of discussions involving engineers, regulatory experts, and quality specialists.
• Discussions around packaging validation are ongoing, reducing common misconceptions and reinforcing compliance.

By adopting an all-in-one QMS solution, companies can unify documentation, reduce errors, and streamline their packaging quality processes.

Conclusion

Medical device packaging operates at the intersection of engineering, science, and regulation. From the sterile pouch to the pallet crossing oceans, every layer must meet strict engineering, scientific, and regulatory standards. Every packaging process decision, whether in material selection, labeling, or validation, represents a choice with consequences for patient safety, regulatory standing, and business performance.

True leaders in the field go beyond compliance checklists. They engage in careful considerations at the design stage, integrate comprehensive packaging validation into their quality management system, and treat every inspection as an opportunity to refine—rather than just confirm—performance. This approach transforms packaging from a regulatory obligation into a competitive advantage.
