Migration of Chemical Compounds from Packaging …
The highest migration of fatty acid amides occurred from polyolefins (LDPE) to olive oil. Additive migrations from LDPE were as follows: 88%, 98%, and 95% for oleamide, erucamide, and stearamide, respectively. Slip additive migration was highest from 65 μm LDPE film, compared to PVC or PS films (<1% of the total compounds).

Three concentrates were chosen to be incorporated into the film for the study: 1. 20% DE in an LDPE carrier. 2. 50% talc in an LLDPE carrier. 3. 70% CaCO3 in an LLDPE carrier. Films were blown on a Killion lab-sized film line adding these masterbatches at a rate to yield 2500, 5000, 7500, and 10,000 ppm of the antiblock in the final film.
