Slip agents are added to polyethylene (PE) films because of their ability to modulate film surface properties such as coefficient of friction (COF) that are critical in film processing. Certain storage conditions such as elevated temperature impact the levels of slip agent present at the film surface during subsequent processing. The migration of erucamide in heat aged polyolefin films will be discussed as studied using Atomic force microscopy (AFM), X-ray photoelectron spectroscopy (XPS), secondary ion mass spectroscopy (SIMS) and infrared spectroscopy (IR). Examples showing surface chemistry and morphology of PE films containing erucamide that were heat aged at different temperatures will be discussed.<br/>
