Leak Testing Blister Packages Using OptiPac Technology

Leak Testing Blister Packages Using OptiPac Technology

Blister packaging is a popular form of packaging used in the pharmaceutical, medical device, and consumer goods industries. It consists of a cavity or pocket made from a formable web of plastic or aluminum, which securely holds the product (such as tablets, capsules, or small devices) and is sealed with a lidding material.

Ensuring the integrity of blister packages is of utmost importance, especially for products that are sensitive to moisture, air, or contaminants. A leak in the blister package can compromise the quality, efficacy, and shelf life of the enclosed product, leading to potential safety risks for consumers and financial losses for manufacturers.

Leak testing is a critical quality control process that assesses the seal integrity of blister packages to identify potential leaks or weak seals. By performing leak testing, manufacturers can identify defective packages and take corrective action before products reach the market.

OptiPac Technology for Blister Package Leak Detection

The OptiPac One-Touch Tool-less system is designed for non-destructive Container Closure Integrity Testing (CCIT) of blister packages. It is a deterministic technique that utilizes volumetric imaging in vacuum together with topographic imaging to identify leaks and where they are located. The OptiPac employs controlled inputs and measured outputs using concepts similar to those used in a vacuum-based dye ingress test, but without the inconvenience and reliability difficulties of the dye ingress approach. By utilizing One-Touch Technology, OptiPac provides a quick test cycle without the need for complicated parameter modifications or changeovers, as seen with other non-destructive blister package inspection systems.

OptiPac Blister Package Inspection System which makes use of volumetric imaging technology provides high levels of sensitivity and reliability. The volumetric imaging method uses many imaging techniques with a complex deep algorithm. The test operator selects a recipe for the blister package using the HMI touch screen, then arranges it in any direction on the test plate. Vacuum is drawn to a predetermined vacuum as soon as he presses the start button. Under vacuum, the blisters enlarge, and any air leaks cause the air to be forced out of the blister. If the blister has a leak, air enters the chamber and collapses the blister cavity. To identify which blister cavities are defective, volumetric images and measurements can be acquired during the test technique. Additionally, the system shows the quantitative measurement for each product tested along with a clear pass/fail result.

OptiPac’s insightful technology offers a suite of advanced functions:

  • Auto configuration for easy recipe setup and validation of new blister formats.
  • Auto orientation of blister packs (test blister packs in any position –no specific orientation).
  • Auto calibration is an integrated one-touch function.
  • Advanced batch reporting with audit trail including image of blister pack and defect results.

OptiPac Benefits

  • Non-destructive technology - Pass/Fail results backed by quantitative test data.
  • No changeover to test different blister formats.
  • Pre-loaded recipe library with easy recipe setup and validation of new blister formats.
  • Completely tool-less.
  • Identifies defective cavity.

Proper leak testing can improve production efficiency and reduce waste by identifying and resolving issues in the packaging process promptly. It enhances overall product quality and increases consumer confidence, which are essential factors for maintaining a competitive edge in the market.

As technology advances, we can expect further developments in leak testing methods, leading to even more accurate, efficient, and cost-effective solutions. Manufacturers should stay updated on these advancements and continuously improve their testing procedures to stay at the forefront of quality assurance.

Understanding Airborne Ultrasound Technology

Understanding Airborne Ultrasound Technology

Since many years ago, manufacturers have tested the quality of container closures, and their perceived value has constantly grown. Companies that once relied on probabilistic techniques like the blue dye test are now aiming to use a more reliable and predictable procedure for integrity testing of various package formats. The pharmaceutical industry is getting ready to adapt to the deterministic testing world in order to enhance quality, increase efficiency, and comply with changing regulatory standards.

Overview of Airborne Ultrasound Technology

Airborne ultrasound technology is a seal quality inspection technique. It is an ASTM test method F3004, the FDA approved standard for seal quality testing. Such tests are mainly performed to provide enhanced seal quality testing of pouches, flexible packages and tray seals. Airborne ultrasound technology ensures in-depth seal quality analysis and applies to multiple packaging materials including Tyvek, paper, foil, film, aluminum, plastic and poly.

In this technique, sound waves are reflected when ultrasound waves pass through the package seal. Signal strength is reduced or eliminated in the presence of leakage / fault. Such deviations are closely monitored to detect leakage. The inability to detect non-leak defects is a common challenge faced by most leak test methods. However, with Airborne ultrasound technology, users can identify various types of seal defects; visible and invisible, leaky and non-leaky, process-related and random.

Seal-Scan and Seal-Sensor Technology

Seal-Scan and Seal-Sensor are the two variants of Airborne ultrasound technology that utilizes non-contact airborne ultrasonic testing technology. With advancements in the form of seal-scans and seal-sensors, Airborne ultrasound technology has proven to be the most effective method for non-destructive seal integrity testing in both offline laboratory testing for seal quality analysis and 100% inline testing on the production line.

Seal-Scan® is a non-destructive offline technology that is highly effective in inspecting and analyzing pouch seal defects. It is a deterministic, quantitative, high-resolution package integrity testing method for identifying defects and sealing integrity for consistency. What makes this technique unique is that it is a non-invasive technique and requires no sample preparation. Seal-Scan® provides advanced digital imaging software tools for process control, offering in-depth seal quality analysis. This technology is capable of producing opto-acoustic images and detailed statistical analysis using L-scan and C-scan modes. An L-scan is a single linear scan along the x-axis of the seal that provides a line graph of seal integrity and simulates an online inspection. A C-scan produces multiple scans (in the X and Y-axis of the seal area) that provide a high-resolution ultrasonic image of the seal structure.

Seal-Sensor™ is an Airborne ultrasonic technology (ABUS) that non-destructively inspects the final pouch seal 100% online. The seal sensor detects incomplete seals, partial or weak areas of the seal, and many other common defects in a seal that are visually acceptable, but have that affect product quality, value, and shelf life. A pass/fail result and quantitative, traceable data are produced in less than a second by a single linear scan (L-scan) of the pouch seal. The Seal-Sensor is a definitive, quantitative, rapid and reliable approach to inspecting pouch seals for defects.

Benefits of Airborne Ultrasound Technology

  • Non-destructive, non-subjective, no sample preparation.
  • Accurate and reliable results.
  • Can accommodate a number of packaging formats and materials.
  • Eliminates subjective manual inspection methods.
  • Deterministic inspection method producing quantitative results.
