Seal Strength

Seal strength, often measured as seal peel strength, is a quantitative measure of the force required to separate the sealed layers of a package. It evaluates the material resistance of the seal itself, indicating how well the fused materials hold together under stress. This property is crucial for ensuring packages can withstand handling, transportation, and stacking forces without the seal peeling open. A package with high seal strength may still have microscopic channels that allow the passage of gases or contaminants, which is a separate concern. Testing for this typically involves using a tensile tester or a specialized leak tester that applies a controlled, peeling force to the seal area. The results are usually expressed in units of force per unit width, such as Newtons per 15mm, providing a clear, numerical value for quality control and comparison against specifications.

Seal Integrity

Seal integrity refers to the continuity and wholeness of a seal, acting as a barrier against the passage of gases, microbes, or other contaminants. It is an assessment of whether the seal is physically complete and free from leaks, channels, or weak spots. A package can possess high seal strength but poor integrity if there are pinholes or inconsistent fusion along the seal’s length. This characteristic is vital for products requiring sterility, modified atmospheres, or protection from moisture and oxygen. Methods to test integrity include bubble emission, dye penetration, and vacuum decay tests. We at Labthink provide instruments designed to detect these minute breaches that strength tests might miss. Maintaining seal integrity is essential for product shelf life, safety, and compliance with industry regulations, ensuring the package performs its primary protective function effectively.

Strength Versus

The core difference lies in what each property assesses: strength measures mechanical resistance to separation, while integrity test ensures there are no micro-leaks, pinholes, or gaps that would allow bacteria or air to compromise the sterile environment. Think of seal strength as the “brawn” of the seal—its ability to resist being pulled apart. In contrast, seal integrity is its “health”—an indication of being fully intact and continuous without any breaches. A robust, strong seal might still fail to protect its contents if integrity is compromised by an invisible micro-leak. Conversely, a seal with perfect integrity might be too weak to survive distribution. Therefore, both parameters are critical and often require separate, dedicated testing protocols for a comprehensive package evaluation. A complete quality control strategy must include assessments for both to guarantee that the package is both durable and hermetically secure throughout its lifecycle.

Conclusion

Seal strength is usually determined via a Peel Test (ASTM F88). A strip of the seal is pulled apart by a (tensile tester. Labthink C610H Auto Tensile Tester is professionally applicable to measurement of tensile, peeling, tearing, heat sealing, adhesive, puncture force, opening force, pulling force of various soft package materials.

Bubble Emission Leak Tests

Bubble emission leak testing is a straightforward, qualitative method used to identify the location of a leak. The package is submerged in a water tank and internally pressurized with air. An inspector then visually observes the package for a steady stream of rising bubbles, which indicates a leak path. This method is effective for detecting larger leaks and is relatively low-cost, but it is operator-dependent and may not be sensitive enough for very small, micron-sized leaks. It is a common manual procedure for finished goods and is often used as a go/no-go test. For more precise and automated quantitative measurements, a dedicated seal tester is typically employed in a laboratory or production environment to provide more reliable and repeatable data.

Vacuum Decay Leak Detection

Vacuum decay leak detection is a non-destructive, quantitative test method ideal for rigid and semi-rigid packages. The package is placed in a sealed test chamber, which is then evacuated to a predetermined vacuum level. The system monitors the vacuum level for a specific duration; a rise in pressure inside the chamber indicates that air has leaked out of the package. This method is highly sensitive and can detect very small leaks. It provides objective pass/fail results and is well-suited for automated production line integration. We at Labthink develop instruments based on this principle, which is widely used for testing vials, ampoules and other sealed containers in the pharmaceutical and food industries to ensure product integrity and compliance with regulatory standards.

Dye Penetration Leak Test

Dye penetration testing is a destructive method used specifically to locate leaks in the seal area of porous and non-porous medical packaging, such as Tyvek pouches. A liquid dye is introduced to the seal area, the leak can be observed by the operator. While highly effective for pinpointing seal defects, this method destroys the test sample and requires manual inspection. It is a recognized standard for validating the sterility barrier of medical device packaging, ensuring that no contaminants can enter through faulty seals during storage and handling.

The Challenge: Biologic Sensitivity

Biologics (vaccines, monoclonal antibodies) are highly sensitive. Infinitesimal ingress of oxygen or microbes can trigger protein aggregation or loss of sterility. A CCS must be qualified with extreme rigor to maintain a robust barrier under all storage conditions.

1. Container Closure Integrity (CCI): Verifying that interfaces (vial/stopper or syringe/plunger) prevent the passage of microorganisms and gases.
2. Barrier Performance: Quantifying how materials limit water vapor and oxygen transmission—vital for lyophilized or liquid-stable drugs.
3. Mechanical Performance: Ensuring components like crimp seals and plunger rods withstand the physical rigors of the supply chain.
4. Stability Integration: Monitoring how aging affects seal integrity through real-time and accelerated stability programs.

Modern testing platforms generate high-fidelity data earlier in the R&D cycle, reducing the risk of late-stage failures.

This article explores how a dual-testing approach, combining qualitative leak detection with quantitative seal strength analysis, provides the rigorous data required for ISO 11607 compliance.

The Integrity Challenge: Why Leak and Seal Strength Tests Matter？

A Sterile Barrier System must remain intact from the point of sterilization until it is opened by a healthcare professional. However, flexible medical packaging faces numerous risks during its lifecycle, including pressure changes during air transport, mechanical shocks during shipping, and compression in storage.

Relying on visual inspection alone is insufficient since micro-leaks or “weak spots” in a seal are often invisible to the naked eye but can compromise the entire sterile field.

ISO 11607-1/2 standards mandate that manufacturers provide documented, quantitative evidence that the SBS maintains its integrity. Therefore, verifying seal performance after simulated environmental stresses (such as drop or compression tests) is a critical component of any medical device packaging validation program.

Rapid Screening with the Labthink C660B Vacuum Leak Tester

The Labthink C660B is a reliable, water-bath vacuum leak tester. It is primarily utilized to screen packaged SBS products for gross leaks, identifying breaches that could lead to immediate contamination.

Application and Methodology

The C660B is particularly effective for testing packs after they have undergone line trials or physical stress simulations. By placing the package in the water-filled vacuum chamber, operators can observe the formation of bubbles, which clearly indicates the location of a leak.

Key Capabilities:

l  Multiple Test Modes: It supports various vacuum levels and hold times to match specific pouch or blister requirements.

l  Standardized Testing: The instrument aligns with standards such as ASTM D3078, providing a repeatable method to screen for seal failures and material punctures across different production batches.

Quantitative Validation with the C660M Leak and Seal Strength Tester

Performance and Precision

The C660M is designed for flexible SBS packs, closures, and tubes. It allows engineers to pinpoint exactly where a seal might be weakening under internal pressure.

Strategic Use of C660M:

l  Burst Testing: Measures the maximum pressure the SBS can handle before a catastrophic failure occurs.

l  Creep and Creep-to-Failure: Evaluates the seal’s ability to hold a specific pressure over time, simulating long-term storage or high-altitude transport.

l  Numeric Data for Validation: Unlike qualitative “pass/fail” tests, the C660M generates precise pressure and time data, which is essential for establishing “worst-case” limits in a sterile barrier system validation study.

Setting Acceptance Criteria and Supporting ISO Validation

C660M helps to establish a numeric baseline for burst strength, allowing manufacturers to set scientific acceptance criteria for their production lines. Meanwhile, the C660B serves as an efficient, daily tool for routine monitoring and post-distribution simulation checks.

Trending this data over time allows for proactive quality control.

For example, if burst strength data from the C660M begin to trend downward, even if the packs still “pass” a gross leak test, engineers can intervene to adjust sealing parameters on the production line before a failure occurs. This data-driven approach is the cornerstone of ISO-driven sterile barrier validation and ongoing requalification.

Deterministic & Nondestructive CCIT

To learn more about optimizing your SBS integrity testing, visit the Labthink website or contact their technical support team for a consultation on ISO 11607 compliance.

Leak Detection Method Sensitivity

The sensitivity of leak detection is dictated by the chosen method’s Lower Detection Limit (LDL). Techniques range from qualitative bubble emission tests, suitable for identifying gross leaks, to quantitative vacuum decay or tracer gas methods capable of identifying minute defects. The required sensitivity is determined by the product’s Maximum Allowable Leakage Limit (MALL);for instance, sterile medical devices demand validated gas-tight seal integrity, while some dry goods may tolerate a higher threshold. Selecting the appropriate method involves balancing detection limits with throughput requirements. For definitive results, many rely on specialized package testing services to validate their chosen approach against industry standards, ensuring the method’s accuracy aligns with the product’s critical requirements.

Technology Limitations in Leak Detection

All leak detection technologies have inherent limitations that affect their accuracy. Factors such as package material, geometry, and the type of contents can interfere with a method’s sensitivity. For example, vacuum decay is highly effective for rigid vials but requires specialized restrictive chambers for flexible pouches. Internal environmental variables, such as the moisture content of the gas inside the package, can affect the pressure changes used for detection.Understanding these constraints is crucial for interpreting results correctly. Organizations like Labthink contribute to the field by researching these variables, helping to define the practical boundaries and capabilities of different testing instruments, which guides users in applying the most effective technology for their specific application.

Conclusion

Vacuum Leak Test Definition

A vacuum leak test is a non-destructive quality control procedure used to identify and locate leaks in sealed packages or containers. The test involves placing the packaged item inside a sealed chamber and evacuating the air to create a vacuum. If a leak is present, air or gas will escape from the package into the chamber. This is detected either by a pressure rise in the evacuated chamber in the Vacuum Decay method setup,  or by observing bubbles escaping from the package while submerged in a water bath in the Bubble Emission method setup. This method is essential for verifying the seal integrity of packaging, ensuring it protects the contents from environmental factors. The reliability of this test depends on the use of calibrated precision test instruments to apply and monitor the vacuum level accurately. It is widely applied in industries like food, pharmaceuticals, and medical devices to prevent contamination and preserve product shelf life.

Vacuum Leak Test Procedure

The standard vacuum leak test procedure begins by placing the package into the vacuum chamber, which is then securely sealed. The air is evacuated from the chamber to a predetermined vacuum level, which is held for a specified time. During this period, the vacuum chamber is monitored for pressure change, indicating a leak. In bubble emission method setup,  the package can be submerged in water, where a stream of bubbles will emanate from any leak path. The entire process must be carefully controlled, with parameters like vacuum level and dwell time set according to the package’s material and design specifications. We at Labthink provide equipment that automates much of this process, ensuring consistent and repeatable results. Proper procedure execution is critical for accurate pass/fail determinations and maintaining product quality.

Vacuum Leak Test Results

The test result is determined by comparing the observed pressure increase  during the measurement cycle against a validated threshold. A result is considered a ‘Pass’ only if the pressure rise remains within the statistical limits of a non-leaking reference sample.

A pass result indicates that the package seal is intact and provides an effective barrier, which is critical for product safety and longevity. A fail result means a leakage in the packaging and the integrity of the container is compromised. These results are quantitative, allowing for comparison against established acceptance criteria and quality standards.

Accurate results help manufacturers identify flaws in their packaging processes, enabling corrective actions to be taken prevent non-conforming products from reaching the market.

Conclusion
