Abstract

In this study, two biodegradable polymer(PLA, PBS) emulsions were treated on agricultural packaging paper such as fruit bagging paper. Water-repellency, mechanical properties, and SEM image with thermal aging were measured on the emulsion treated fruit bagging paper. Biodegradable polymers(such as poly lactic acid, poly butylene succinate) emulsion treated fruit bagging paper had higher water-repellency and strength than other water-repellent(such as acrylic repellent, linseed oil and paraffin wax) treated fruit bagging paper. According to FE-SEM results of polymer emulsion coated fruit bagging paper, the colloidal particles of emulsion after thermal treatment (looks like being) were adhered to the fibers. Thus, using biodegradable polymer emulsion is expected to protect a fruit for a long time.
