I just had a look at two of my non-Tetley teabags. They appear to be stitched closed with the end of the string. Why does it need plastic? Edit: The quote from the FAQ mentions the bags being biodegradable, and this page [1] about their "new biodegradable bags" shows a photo of bags without strings. So maybe it's just these stringless (and presumably cheaper to manufacture?) bags that contain plastic? The Twinings FAQ [2] doesn't mention plastic: "Our teabags are biodegradable, plant-based teabags and will break down within 6 months if placed into a local authority compost caddy, though it may not compost as quickly if left in garden compost (as typically these are not sufficiently hot)."
