The Hidden Challenges of Serialization: Substrate Material

Part II of a three-part series looks at the importance of substrate materials in serialization.

Before the Drug Supply Chain Security Act (DSCSA), European Falsified Medicines, and other global legislation, if a label convertor or a carton manufacturer could find ways to remove cost out of their packaging and pass savings along to customers, it was usually considered a major positive.

In a world where serialized content is now the norm, and where—as we learned in part 1 of Exploring the Hidden Challenges of Serialization—codes aren’t just read, but are graded, which are two very different applications.

A small change to the surface area of a plastic label could have a drastic effect on a thermal-transfer ribbon printer’s ability to adhere ribbon to the surface of a package. Changing a ribbon could be an option, but does that mean a line should be revalidated—all because of a seemingly innocuous change to a label?

How about a carton manufacturer that attempts to do you a favor by changing the mineral layer to save costs? An incorrect mineral layer can cause a bad code, so that one-tenth of a cent savings might mean that now the laser being used can’t get the energy to absorb correctly, and now a distributor or wholesaler won’t accept your cartons. (See Substrate Materials Composition image.)

These are all changes that happen sometimes without a customer being advised, and almost always the first thing to do is blame the printer because, after all, it’s just a printer. Right?

The positive thing to take away is that as serialization becomes a larger part of the world, most label and carton manufacturers are learning that changes including the ones mentioned above—and others—can’t be done without alerting the customer anymore. Even better is that some suppliers are investing heavily into learning about material science, and imparting that knowledge on to account managers and sample lab personnel.
