Poly means many. Ester refers to the specific chemical bond. What makes it a plastic is the specific monomers, the individual parts that get bonded together to make the chain.
Look up, if you're curious, the 7 most common plastics in the US, the ones in the numbered recycle symbols. Only 2 of them are actually recyclable. The labeling is deliberately deceptive. The plastic industry did that specifically to give people the impression it was recyclable, even though it wasn't. They told regulators that a universal symbol was necessary and that industry could work out waste disposal processes for plastics as long as they were numbered and identified. True, but deceptive.
Anyway, if you look at the names, you'll see they're all "poly" something. They're all chains of the various alkanes (the chemical name for the base links in that chain).
