Abstract
The objective of this work is to demonstrate the usefulness of short fibers dispersed films over the conventional films. Composite films based on dispersion of PET short fibers and LDPE were prepared by melt extrusion. The fibers / LDPE weight ratios amounted to 5/95, 10/90, 15/ 85, 20/80, 30/70, respectively. Specimen films were processed in two roll mill. Samples of each stage of composite films’ manufacturing and processing were characterized by means of scanning electron microscopy (SEM), wide-angle X-ray diffraction (WAXD), oxygen permeability, mechanical testing, dart impact and heat seal strength.
