Polyolefin Plastomer films formulated with slip and antiblock were blown on a wide die gap with and without two
DynamarÔ polymer processing additives (PPAs). A wide die gap was used so that melt fracture-free film could be
obtained with no PPA present for comparison purposes. The films were analyzed for the following properties:
surface tension (on treated films), gloss, haze, clarity, transmittance, hot tack, heat seal, COF and block. In
addition, the surface of films was examined using ESCA (Electron Spectroscopy for Chemical Analysis) and SSIMS (Static Secondary Ion Mass Spectrometry) to determine the surface chemical composition.
