Volumetric Imaging Technology

OptiPac inspection system for multi-cavity blister packaging features tool-less changeover for different blister package formats.

Blister package manufacturing consists of materials such as plastic or foil formed into cavities that house the tablets or capsules, providing the barrier against environmental contaminants for the product’s shelf-life. In the dye ingress test, the package is visually inspected for blue dye penetration after it has been subjected to a vacuum cycle submerged in dye. While the method seems simple, there are several conditional aspects to the method that can contribute to unreliable results and make the method less effective at assuring quality.

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 adult trail including image of blister pack and defect results

The OptiPac One-Touch Tool-less system is designed for non-destructive blister package leak detection. Using principles similar to those applied in a vacuum based dye ingress test, the OptiPac applies controlled inputs and measured outputs without the hassle and reliability issues of the dye ingress method. OptiPac uses a volumetric imaging technology to measure the motion of a blister package under vacuum to detect leaks. The interface is practical and simple to setup with new blister package formats, requiring no tooling changeover or complex parameter adjustments experienced with other non-destructive blister package inspection systems.

The sample is placed on the testing area for vacuum-based measurement. After pressing the start button, vacuum is pulled to a defined vacuum. The blisters expand under vacuum, driving air out of the blister through any leaks present. If there is a leak in the blister, the air escapes into the chamber leaving a collapsed blister package. During the dynamic vacuum test sequence, a volumetric measurement reading is taken which determines which blister cavities are defective. A definitive pass/fail result is displayed as well as the quantitative measurement associated with each package test. Like other VeriPac systems, the OptiPac provides a definitive result based on accurate and measurable quantitative data, reliably detecting leaks down to 5 microns

The universal nature of the system comes from its ability to adapt from one package format to the next. The system captures the volumetric data from each cavity, adapting to different cavity shapes, sizes and arrangements of different blister pack formats. The intelligent measurement adaption allows for testing different package formats with absolutely no change-over, making it the most simple and universal blister package inspection system.
