Some plastics are worse than others. ABS, BPA, BPS, PFAS, etc. are really bad. Polycarbonate releases toxic fumes during manufacturing but it’s considered non-toxic afterwards.

PLA is plant-based and decomposable. Polyethylene is inert/non-reactive and non-toxic. Cellophane is literally made from cellulose.

I don’t really know about polypropylene, polyurethane, polystyrene, or polyester.

Then there’s vinyl and nylon. Fairly certain those are inert and non-toxic, but I’m not 100% certain.

Then you’ve got latex and natural rubber which some people have allergies to but they aren’t intrinsically toxic as far as I’m aware. Synthetic rubbers vary in toxicity. I don’t know about neoprene for instance, but silicon is inert and non-toxic.

The problem is “plastic” is such a broad term, and to a lot of people, all of the above are just “plastic.” The fact is there are a variety of plastics and choosing your material intelligently can make all the difference.

Of course, microplastics are a whole nother issue even aside from toxicity…
