2026 Pharma Guide - Efficient Container Closure System Qualification for Biologics


To accelerate time-to-market for life-saving therapies, manufacturers must move toward data-driven Container Closure System (CCS) qualification. By leveraging high-precision, nondestructive testing, teams can ensure regulatory compliance and patient safety throughout the product lifecycle.

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.

  • Nondestructive Leak Detection: Using vacuum and pressure decay methods, Labthink C690 Nondestructive Leak Detection systems detect micro-leaks in vials and syringes without damaging the sample.


  • Comparative Barrier Analysis: Labthink’s C403 and C406 Oxygen/Water Vapor Transmission Combo Systems allow for simultaneous material testing, ensuring the best material match for moisture-sensitive biologics from day one.


  • Mechanical Stress Testing: The Labthink C610 Series evaluates seal strength and plunger movement force, simulating high-speed filling lines and global transport stresses.
  • Worst-Case Mapping: Identify failure points (e.g., oxygen ingress in pre-filled syringes) early and focus testing on these high-risk scenarios.
  • Accelerated "Snapshots": Pair thermal stress with nondestructive CCI testing to gain early confidence in long-term stability before two-year markers are reached.
  • Platform Transferability: Standardize testing across vials, cartridges, and syringes using shared Labthink platforms to shorten qualification timelines for future pipeline products.

Data-Driven Confidence

Transition from subjective methods to high-precision, traceable platforms. Labthink provides the instrumentation necessary to ensure your qualification data is accurate, repeatable, and ready for regulatory scrutiny.

Comprehensive Quality Control for Stretch Wrap Film Performance

Image
Stretch wrap film has become an indispensable packaging solution globally, used to tightly secure goods for efficient transportation and reliable storage. Its versatility stems from its unique properties: lightweight yet strong, highly elastic, self-adhesive, and capable of conforming to any shape without damaging the contents. Produced through advanced cast film extrusion processes, these films boast excellent tensile performance, tear and puncture resistance, high transparency, superior self-adhesiveness, and impressive retraction rates, ensuring packages remain compact and secure. From chemical raw materials and food products to electromechanical goods and textiles, stretch wrap film provides crucial protection, with specialized types like PE (eco-friendly) and PVC (specific uses) catering to diverse needs. The Imperative of Quality Control Given its critical role in safeguarding products throughout the supply chain, the consistent quality of stretch wrap film is paramount. Manufa...

Case Study: Oxygen Barrier Properties of Recycled PET Bottles

Image
Recycling plastic bottles is vital for environmental protection, but it can affect their oxygen barrier properties, making them less suitable for oxygen-sensitive products. Our case study on PET bottles with varying amounts of recycled material found that increasing the recycled content from 25% to 50% only slightly reduced their oxygen barrier. This suggests that using more recycled material does not significantly compromise the bottles' performance. The Problem The growing trend of recycling waste plastic bottles requires an understanding of how reclaimed materials affect a product's performance. For PET bottles, a crucial metric is their ability to act as an oxygen barrier. High oxygen permeability can compromise the quality of packaged goods, limiting the use of recycled materials in food and beverage containers. This study aims to quantify that effect by testing bottles with varying percentages of recycled content. The Test Two types of PET bottle samples were tested...

How to Test Oxygen Permeability of Food Packaging According to ASTM D3985 Standard

Image
  How to Test Oxygen Permeability of Food Packaging According to ASTM D3985 Standard   Oxygen transmission rate is a crucial indicator for evaluating the barrier properties of packaging materials. For food packaging, excellent oxygen barrier performance is essential to ensure food safety and effectively extend shelf life. ASTM D3985, "Standard Test Method for Oxygen Gas Transmission Rate Through Plastic Film and Sheeting Using a Coulometric Sensor," is a standard test method that employs the coulometric sensor principle to measure the oxygen transmission rate of plastic films, sheeting, laminates, paper-plastic composites, plastic-coated fabrics, and similar materials. This evaluation helps determine the packaging material's ability to block oxygen, ensuring food remains unaffected by oxygen throughout its shelf life. Understanding the Coulometric Sensor Method The coulometric sensor method involves clamping the test specimen (the food packaging material) into a per...
