This provides the packaging engineer strong visual acuity as to the nature of basic seal integrity. With a gentle tap of the seal inspection switch on top of the unit, the light source is activated. The LED cluster provides a finely tuned light wash over the seal area. This light wash is angled in order to invoke shadows over the topography of the pouch seal area. As the operator views the seal area through the 3x lens, seal anomalies are exaggerated. The Viú® is designed to allow the operator to pull a flexible pouch from either the left or right side, allowing the complete inspection of pouches of any size. As many packaging engineers develop dialogue within their SOPs that utilize visual pass/fail inspection, it is becoming increasingly more important that a more repeatable system be implemented.
