100% Identification of Defective Blister Packs by Sepha’s VisionsScan According to New Whitepaper

Belfast, Northern Ireland (PRWEB) March 04, 2013

Four blister pack types of various designs and materials were evaluated by Dr. Dorian Dixon for his latest whitepaper on Sepha’s Visionscan. Laser drilled holes of 15m or 50m were drilled into the foil or paper laminate of 25 of each of the four pack types, creating a total of 200 initial test packs. Only one pocket per pack was laser drilled, leaving the remaining pockets undamaged as control pockets. Scanning Electron Microscopy (SEM) was used to confirm the dimensions of the laser drilled holes.

On SEM inspection of the initial 200 test packs it was shown in a number of blister packs that the laser drilled holes were not drilled correctly or were missing. Data from the pockets identified as having defective holes was not included in subsequent analysis, resulting in a total of 170 test packs for final analysis. Once all such incorrectly drilled pockets were removed from the data, the study showed that VisionScan from Sepha correctly identified 100% of both the 15m and 50m sized defects in a total of 170 test packs across all four of the blister pack types.

Commenting on the results, Dr. Dixon said As VisionScan is a tool-less, non-destructive test using state-of-the-art vision technology, it removes the possibility of human error and subjectivity, whilst allowing valuable product within defective packs to be recovered. This represents a significant improvement over traditional blue-dye testing, which is both subjective and destructive.”

Sepha Ltd. CEO John Haran commented Dr. Dixons study and findings demonstrate the VisionScans ability to offer a technologically advanced, non-destructive alternative for the integrity testing of blister packs, whilst delivering quality improvements and cost savings during production for global pharmaceutical manufacturers.

Sepha serves the needs of the global pharmaceutical blister packing and leak testing markets and is doing business with many of the worlds top pharmaceutical manufacturers including Boots, Bayer, Novartis and GSK. It designs and builds machines at its factory base in Dundonald, Northern Ireland, and exports them to over 60 countries worldwide. For more information visit the Sepha website.
