Phthalate residue in PE resins?

20 December 2019 0 5K Report

I wanted to know how phthalate residues show up in samples of containers/bags made from Polyethylene (chiefly HDPE) . From my understanding, there is no presence of an external or internal donor for the ZN catalysts used to make PE. The donors were phthalate based in the 4,5th generation of catalysts for manufacturing PP.

Please advise.
