It happens to all of us from time to time, we make mistakes.........

One of the most frequent recoverable errors is the coding of blister packs.
For small quantities, these are either destroyed or the product recovered and re-packaged.

When the volumes are larger, or for H&S/GMP reasons the tablets or capsules cannot be recovered it is necessary to securely remove the embossed or printed code/date.

One solution, is the cropping of the blister, allowing for the offending text to be removed and the packs ink-jet coded with the correct information, prior to being released to market.

There are three hurdles to overcome:  

• Volume, the process needs to be quick enough to justify the time spent recovering the product.
• Accuracy, all blisters must look identical, blister packs are rarely flat, and this causes mechanical handling issues.
• Finally, the blister must appear as good as the first, therefore the radius must blend perfectly so as to not leave any sharp edges or "tell-tale" marks.
  

Over the last 18 months Toolrite has prepared 3 such units, recovering as many as 8 blister packs per cycle. Two were designed for removing the incorrect code, one on one edge, the other on both edges. The third was modified to re-introduce a "full-cross" perforation to a blister which had been omitted in production.

The basic design principle allows for future modification of specific components, and to allow for a series of change parts to be assembled if needed.

Toolrite's design and manufacturing process bring effective initiatives quickly to our clients.
