Abstract
A paper like synthetic polymer film is a film made up of synthetic polymers and is a synthetic alternate to conventional cellulose paper. These films have good whiteness index. Papers like synthetic polymer films have better resistance to water, oil and grease as compared to conventional papers. In present work paper like synthetic film was prepared by blown film extrusion process with Linear Low Density Polyethylene and coated Calcite, Talc and Titanium oxide as filler. Effect of various filler on Opacity, Whiteness index, Tensile strength, Tear strength and Surface Gloss were studied. Linear low density polyethylene with calcite as filler ( 10%,20%,30%,40%) and mixture of calcite and talc( 45%,50% and 55%) and titanium oxide ( 5% and10%) were compounded. The compounded pellets have been processed to synthetic paper with the help of blown film process. Blown film unit consist of a single screw extruder of size 25mm. The twin screw extruder used for compounding is counter rotating extruder with L/D ratio of 28:1. The size of extruder is 45mm with four zone temperature controller. There was increase in opacity and whiteness index with increase in filler percent with calcite as filler. However surface gloss, tensile strength and tear strength decreases with increase in filler percent with calcite as filler. There was increase in opacity and whiteness index with increase in filler percent with mixture of calcite and Talc and 5% Tio2 as filler. However surface gloss, tensile strength and tear strength decreases with increase in filler percent. There was increase in opacity, whiteness index, surface gloss and tensile strength with increase in filler percent with mixture of calcite and Talc and 10% Tio2 as filler. However tear strength decreases with increase in filler percent. Mathematical modeling and optimization process was carried out.
