Studies of printing inks on starch blended and surface grafted polyethylene film for flexible packaging

Abstract

Grafted vinyl acetate surface of starch blended biodegradable polyethylene film was printed with industry standard printing inks based on polyamide resin and organic solvents. Various print and packaging properties were studied to find suitability of the use of such grafted polyethylene film in comparison to ungrafted starch blended polyethylene film and industry standard corona treated polyethylene film. The use of such grafted film was also comparatively studied in polyethylene laminate packaging. Prints and laminates using industrial standard grade polyethylene, starch blended biodegradable polyethylene and grafted starch blended polyethylene film, were put on soil burial test and studied for biodegradable properties.
