* SUBJECT
 -Study on the Properties of Low density polyethylene  blends films
 
 
 * Abstract
 Plastic packaging materials are considered as non- environmental friendly materials because of their slow
degradable natures. In this study, four different types of  low density polyethylene(LDPE) films were prepared
by the additions of degradable master batch(M/B), starch, soybean oil or citric acid to increase degradability
of LDPE.
 
Also this research has been aimed to improve the compatibility of LDPE with degradable M/B or starch by addition
of soybean oil or citric acid.
 
Mechanical properties, oxygen permeability and degradability under UV radiation of films were evaluated.
The addition of degradable M/B and other additives did not significantly altered tensile strength and percent elongation
at break of films except starch added films. The degradability of LDPE films under UV radiation increased with increasing
degradable M/B contents. Under UV irradiation, the reduction of mechanical properties of films occurred faster than that
of permeability values.
