      My knowledge of polymers is sufficient (university degree in related
      chemistry field + working experience), maybe little rusty, but I'm
      absolutely sure, at least, that LDPE is nizkohustotni polyethylen. More,
      the same (LDPE) polyTHethylene sold on amazon is called only
      polyethylene on the webpages of its manufacturer.

      As for University of Delewere - we don't know who wrote it and from
      which sources ... Maybe he was misled in the same way (because there is
      several type of polyethylene (low and high density, linear and crosslinked).

      So, in my opinion, somebody made mistake and others are spreading it
      throughout Internet. We can call it polyTHethylene virus.

        nejen polyethylenova folie, ale treba i polypropylenova nebo jina,
        zkratka jakykoli pruhledny foliovity plast.

        A taky by slovo polythene mohl byt zdroj zkomoleniny polythethylenu.

                The problem was more insidious than a mere typing error (however frequent).
                In quite a few sites the two words appear together. To make matters worst,
                this also was found to be the case in a single sentence: "The outer
                polyethylene shell was then finished, and an inner circular sleeve of
                polythethylene was slid into each column of lead".
                PolyTHethylene also was offered for sale as such on Amazon.com.

                As Jan Kordac put it "We can call it polyTHethylene virus."
                Not easy to recognise unless you are a chemist!

                I find Google an invaluable tool for our profession but I must admit that
                for me this was quite a humbling experience and an eye-opener.
