| Abstract | The objective of this study was to determine the effect of variables on the property of low density polyethylene (LDPE)/bagasse f ilm. Two variables are focused and studied. These two variables are the bagasse content and the stretching ratio during the f ilm forming. The proportion of bagasse in the range of 0-20% (by weight) was mixed with LDPE, and then it was processed to be a thin f ilm by blowing film extruder with various stretching ratio (i.e. 100, 135, 150 and 170%). Properties of these f ilms such as mechanical property, water vapor and oxygen permeation rate and fractured surface of the f ilm under scanning electron microscope (SEM) were determined and analyzed. The results showed that as the bagasse content is increased, both the tensile strength and elongation at break of the f ilm decreased. An increase in stretching ratio during the f ilm forming caused an increase in tensile strength but it caused a decrease of elongation at break of the f ilm. Increasing of both stretching ratio during the f ilm forming and the bagasse content enhanced the water vapor transmission rate (WVTR) and oxygen transmission rate (OTR) of the film. |
