Those are likely PET bottles which are highly recyclable. There are a few plastics that are recyclable in large enough pieces. It's just that so much of our packaging and products are just mixed or thin plastics with a lot of printing which are not in any way recyclable.

Now when I say recyclable I mean plausibly do-able at scale, with a decent quality output material suitable as feedstock for manufacturing, not profitably recyclable. I don't think any plastic recycling is profitable.
