Inspection Technologies for Tablets & Capsules Packaging

Non-destructive seal and leak testing equipment for Tablets & Capsules in multi-cavity blister packs, sachets, and induction sealed bottles


Blister packaging is one of the most practical and convenient packaging formats for tablets and capsules. Blister packaging is specifically used for tablets and capsules to pack them in a convenient and controlled way for easy patient use.

Blister packaging is designed for long and tamper-proof shelf life by eliminating moisture ingress and contamination. In today’s drug delivery systems where certain drugs are extremely sensitive to moisture and Oxygen, it is critical to ensure the package integrity of blister packs to ensure that product quality is not compromised.

Vacuum decay is a non-destructive container closure integrity testing method for blister packaging. PTI offers two technologies for integrity testing of multi-cavity blister packaging.

OptiPac One-touch Tool-less Blister Package Leak Testing
Non-destructive package testing of multi-cavity blisters

The OptiPac One-Touch Tool-less Leak Detection System is a deterministic non-destructive technology designed specifically for multi-cavity blister packs. OptiPac utilizes volumetric imaging under vacuum with topographic imaging to detect the presence and location of leaks. The OptiPac is engineered and designed with One-Touch Technology to achieve a rapid test cycle requiring no changeover or sample preparation. Operators simply place the blister package on the test plate and press the START button. Blister packs can also be placed in any orientation or position. Within seconds, the operator sees a definitive pass/fail result, and a visual identification of blister cavity defects. OptiPac technology is unique in that it can provide rapid detection of sub-5-micron defects depending on blister cavity volume. OptiPac requires no tools for different blister formats.

OptiPac Benefits:

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

Inspection Criteria

  • Leak detection and seal integrity testing of entire package
  • Test sensitivity down to 5 microns


VeriPac 410 for All Low Headspace Packaging

The VeriPac 410 inspection system offers non-destructive seal and leak detection for blister packs, sachets, and pouches with low headspace (suture packs, transdermal product packaging).

  • Applications include blisters, sachets, transdermal patch packaging, suture packs
  • Vacuum decay and force decay measurement technology

Multi-cavity blister packs and low headspace packaging use a variety of test methods to determine package integrity, with most being destructive, subjective, and unreliable.

The VeriPac 410 utilizes a combination of vacuum decay technology and force decay measurement to identify defective packages. Multiple packages can be tested in a single test cycle, and the 410 identifies which package or cavity is defective. Test results are quantitative and provide operators with a definitive pass/fail, eliminating the subjective and destructive nature of current test methods.

Package quality assurance is achieved by deploying accurate, reliable non-destructive inspection methods, removing subjectivity from the testing process while reducing waste. The VeriPac 410 allows the tested product to be returned to the production line and eliminates the significant costs and waste associated with destructive leak test methods.
