    Out of context, it means nothing at all. – Janus Bahs Jacquet Sep 8 '14 at 7:17

Welcome to the site. Best guess given lack of context is that this is is form an audiologist's order or a hearing assist device. Polypropylene is the material from which the exterior of the device is to be made, and ear right / left is for the audiologist to specify whether the device is for use in the right or left ear.

  • I work in the field of polymers—"ear right/left" definitely has no connection to the materials themselves. So this seems as likely an explanation as any. – aeismail Sep 8 '14 at 9:25
