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'm not sure where that part of the post comes from. The source says "The judge said he will apppoint(sic) an independent receiver to manage the dissolution of the corporations whose business certificates he canceled." Which I can only take to mean that the judge is doing the appointing, not Trump.
