I had just gone back and seen that, too, while you posted. I was trying to go back and delete my post about them after I saw it. Maybe you could ask the seller for clarification, but the pic of it showing the open bottle without a cap DOES look like it's PET...as LDPE isn't totally clear. I'm sorry I didn't read his description toward the bottom sooner.
If you want easy to squeeze, but
not PET, the choices would be LDPE or PP.
