Trivia Question - test strip bottle liners?

Does anyone know what the liner is inside the test strip bottles or what it’s for?

It’s a desiccant.

Yup, as Sarah said, its function is to keep the strips dry as they can be damaged by humidity. That’s why it’s important never to store or transport the strips in a container other than the one they were packaged in.

And to not store pills in said container…due to chemical content!
