I’m not sure food blogs are the best choice for this. The article goes on to talk about BPA and phthlates, but neither of those exist in pure HDPE or PP.
BPA is found in polycarbonate plastics (acrylic) (Edit: brain lapse, acrylic is PMMA) and epoxy resins. Phthalates are in PVC (vinyl). Using the word ‘plastic’ as a monomer mononym (Edit: lol wrong mono) is dangerous for many reasons, and causation vs correlation is one reason why.
I mean, definitely go with glass if you have the choice, sure, but let’s also actually try to be accurate if we invoke the scientific method.
I would also love for there to be really robust testing of food containers of all varieties direct at the manufacturers, with heavy fines involved if they’re using additives but claiming it’s a food-safe plastic.
For me, it has a picture where it specifies a “polypropylene container”.
There’s also this bit from near the end of the abstract:
Additionally, the polyethylene-based food pouch released more particles than polypropylene-based plastic containers. Exposure modeling results suggested that the highest estimated daily intake was 20.3 ng/kg·day for infants drinking microwaved water and 22.1 ng/kg·day for toddlers consuming microwaved dairy products from polypropylene containers.
So, they’re, at least, discussing polypropylene and polyethylene.
I try to keep it honest and accurate, I would hate to spread more misinformation accidentally. If only my long-covid memory were a little more cooperative!

Here’s the study in question. Can’t speak to the authenticity of it but off the top I don’t see anything shady
It doesn’t look shady, but I can only access the abstract which just says “plastics” and doesn’t specify that part further, unfortunately.

Polycarbonate (BPA monomer) is a very different polymer to acrylic/PMMA (methyl methacrylate monomer).
Oops, my mistake. I’ve been looking at too many acrylics and polycarbonates for use in a non-food setting. Thanks for the correction!
Love all the edits. Thanks for the informative comment.
