Blister Package Inspection Solution from PTI

Blister Package Inspection Solution from PTI

Blister packs are pre-formed packaging that are commonly used for tablets, capsules and certain consumer goods. They are made up of two primary components - a cavity made from a form of plastic or aluminum and a covering made from aluminum, paper or a lamination of soft foil. The cavity holds the product while the covering seals the product in the package.

While filling tablets into blister packs, the product is first fed into the desired cavities followed by sealing the cavity covering. Manufacturers of sterile pharmaceuticals highly depend on package integrity testing to verify product quality and safety.

Package Inspection Techniques

1. OptiPac Leak Detection System

OptiPac Leak Detection System is a non-destructive container closure integrity testing method developed specifically for multi-cavity blister packs. This leak detection method uses One-Touch Technology to achieve a rapid test cycle without requiring any changeover or sample preparation. Practical operation, sensitivity and reliability are the key features that make OptiPac technology ideal for blister package inspection.

To conduct the test, the operator places the blister pack on the test plate and presses the start button. The next step involves pulling vacuum to the desired vacuum level. The blisters expand under vacuum, driving air out of the blister through any leaks present. If the pack is defective, the air escapes into the chamber leaving a collapsed blister cavity. Depending on the blister cavity, OptiPac technology provides rapid detection of upto sub-5-micron defects. Additionaally, the technology displays a definitive pass/fail result along with quantitative measurement for each package tested.

2. VeriPac 410 Series

The VeriPac 410 inspection system utilizes a combination of Vacuum Decay technology and differential force measurement for container closure integrity test (CCIT) and leak detection of blister packs, sachets, and pouches with low headspace, such as transdermal patch packaging and suture packs. This technology can be used to test multiple packages in a single test cycle based on the package specifications. Additionally, it can also precisely identify which package or blister cavity is defective. VeriPac 410 inspection systems are proven to provide quantitative test results with a definitive pass/fail result. Being a non-destructive technique, VeriPac 410 allows tested products to be returned to the production line. This eliminates the cost and waste associated with destructive leak test methods. The ROI for the VeriPac 410 makes this a powerful solution for the pharmaceutical industry.

Benefits of VeriPac 410 Series
