RFID Journal Staff asked 8 years ago I have a reel rolled with plastic, the radius of which is about 13 inches. If I place a passive RFID label in the core, will an RFID reader be able to interrogate the tag?

George,
It would be difficult to provide an answer without knowing what kind of plastic is rolled on the reel. The likely answer is yes, as plastic is generally RF-friendly—that is, RF energy penetrates plastic fairly easily. But it would depend on the plastic's density, as well as the material's dielectric constant. If the material had some metallic properties, that would make it more challenging to read the tag.
