Film Properties and Applications for Lldpe and High Pressure Ldpe Blends

Abstract

Many papers have been written presenting properties expected from different blends of linear low density polyethylene (LLDPE) and high pressure low density polyethylene (LDPE) [1-3]. This paper attempts to corre late the properties obtained from blends with specific end-use markets (i.e., gar ment bags, shrink wrap, ice bags, and general purpose bags). The effect on ex trusion rate, bubble stability and draw down are discussed for blends of butene and hexene LLDPE with fractional melt index (MI), 2 MI, and 6 MI LDPE homopolymers as well as 3% vinyl acetate (VA)-LDPE copolymers.
