Physico-Mechanical Properties of Filled Polyethylene Films

Abstract

The mechanical, optical and electrical properties of low density polyethylene (LDPE) and linear low density polyethylene (LLDPE) films with and without fillers have been studied. The variation of properties resulting from the addition of inorganic fillers included an increase in haze, diffusion of light, and tear strength for films made with both LDPE and LLDPE, while increasing the burst strength and elongation of the LDPE films only. The tensile strength, melt flow rate, and usually the seal strength were decreased with the addition of fillers. The coefficient of friction (COF) was decreased when silica or commercial grade mica were added to both LDPE and LLDPE films.

Effect of maleic anhydride grafted polyethylene on engineering properties and morphology of fumed silica filled polyethylene blown films

“…When these materials are processed during film blowing operation, better end-use properties are expected, besides the improvement in the ability to withstand the tensions during blowing. 4 A lot of research work has been published in the past on the structure-property relationship of HDPE-nanoclay-based composites and blown films [4][5][6][7] and LDPE/LLDPE-silica-based blown films 8 but except for few, 9,10 literatures on HDPE-FS-based composites and blown films are limited.…”
