Design Inputs for a Backer Card
As mentioned, the main reason a backer card would be the preferred material for a medical device is if the device and all its components need to be locked in place. Medical devices that would work well in a sterile package system using backer cards are coil products, tubing, catheters, and devices containing sharp features that could puncture a pouch.



What is the alternative to Backer Cards?
Backer cards, or die-cut insert cards, are often compared to thermoformed trays because they both have the purpose of containing a device from moving or shifting in the package. A thermoformed tray with a retainer is great for containment but it’s more expensive and would require more time to engineer a solution and then manufacture. - https://pkgcompliance.com/benefits-of-using-a-backer-card-fo...
