Abstract
AbstractA range of LDPE/LLDPE films were manufactured by blown and cast extrusion, which were then uni‐axially stretched at regular intervals. The films were analysed to determine the change of diffusion, solubility and permeation coefficient, and the correlation between crystallinity and molecular orientation. It was found that films exhibited a decrease in permeation coefficient with increased uni‐axial stretch as a result in change in crystal type and higher molecular orientation, resulting in a decrease of diffusion and solubility coefficient. This paper shows how double yield phenomena present in the uni‐axial stretching of the LDPE/LLDPE films affect the permeation properties. Copyright © 2008 John Wiley & Sons, Ltd.
