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.
It doesn’t look shady, but I can only access the abstract which just says “plastics” and doesn’t specify that part further, unfortunately.
