  1. Pouch Seal Inspection — Airborne Ultrasound Technology For Better Process And Quality Control

    A pouch seal is a structural element that joins flat film material and a component designed to close a pouch airtight. Traditional test methods (e.g. peel strength or burst), can measure the joint strength of the pouch seal using destructive methods that are often unreliable. Submitted by PTI Inspection Systems

  2. How Important Is The Physical Integrity Of The Blister Package?

    Untold millions of medicinal tablets and capsules are produced every year, and many of the over-the-counter varieties are encased in blister packs for protection. Existing manual methods for inspecting these packages are subjective and lack repeatability, while electronic techniques have to date been stymied by the great variation in blister packages.

  3. Technology Overview: How To Leak Test Blister Packaging

    Most current test methods for blister packages are destructive, time consuming, not sensitive, unreliable, and dependent on the properties of the package lidding material. Small semi-rigid, flexible, and multi-cavity blister packages do not have enough air inside the package to reliably detect defects by simple vacuum decay methods.
