I make PVC and PE for a living, mainly PVC. Someday I need to take pictures of some real steel mirrors. I can probably see out for 10 feet off an extruder die.
Here is a great flow chart for identifying what type of plastic you have.

Here is a thumbnail of the chart as clickbait, yet oddly not clickable.
Short version to make sure something is NOT PVC.
1. Does it float in water? If it does, it is not PVC. An air bubble under your item may float it. Shake them out.
2. Light it on fire (safety first though). PVC will have a green tint to the flame. PVC is generally self extinguishing, as in if you remove the flame it will stop burning. PVC will char and become brittle and black when burned. PVC will give off the smell of hydrochloric acid when burned.
