Functional Overview
This chapter contains information that will help you understand the basics of
the Color CVIM BLISTER-PAK

option from the Allen-Bradley Company.
Here is a list of the main information topics:
•
Background information about the BLISTER-PAK option.
•
Comparison of the Color CVIM BLISTER-PAK option to the basic Color
CVIM system.
•
List of the BLISTER-PAK option’s capabilities and typical applications
for it.
•
Differences among the three basic operating modes: The system setup
mode, the blister setup mode, and the run mode.
•
Application considerations, including performance limitations and
suggested methods of detecting specific types of defects.
Blister packaging is presently used almost universally for pharmaceutical
packaging of tablets and capsules in Europe. Its use continues to grow in
North America.
Important: Although the Color CVIM BLISTER–PAK option is designed
primarily for inspecting pharmaceutical tablets and capsules,
blister packaging is suitable also for other products as well.
Throughout this publication, the words “tablet” or “capsule” are
used interchangeably. Instances in which a characteristic unique
to either a capsule or tablet is important are clearly indicated.
A blister package consists of a substrate (usually polyvinyl chloride (PVC) or
aluminum) into which pockets (or alveoli) have been formed, and a foil
backing that forms a seal. Each material begins as a continuous roll, or web.
After the web is filled and sealed, it is cut apart into blisters. A typical blister
consists of from 10 to 36 pockets.
The Color CVIM system with the BLISTER-PAK option can be used to
ensure the security of blister packaging operations by applying a number of
tests, such as the following, to each tablet or capsule:
•
Verify the presence of the correct color tablet in each pocket.
•
Verify the size of each tablet.
•
Verify the position of each tablet.
•
Detect broken or otherwise defective tablets.
•
Detect the presence of extra tablets or foreign material.
