Once all of the BFS containers in a strip are filled and sealed, they may be taken through an engraver that laser-etches the date, drug product, and batch number into the label tab.
If engraving is not done at this stage, the BFS containers will go through a label machine later in the process.
The filled strip is then automatically moved to a punching machine that removes all the excess plastic. The result is a clean strip of BFS containers.
Depending on the number of units on a strip, the product may then move to a separation machine that breaks up the strip into cards.
In this example, a card is made up of 5 BFS containers.
Cards will usually remain intact throughout the remainder of the process.
