Study the Effect of Surface Treatment of Polyethylene Bottles using Flame and Comparing it with Chemical Treatment
Due to inherent poor adhesion properties of untreated polyolefin, attributed to its low surface free energy and lack of polar groups, the adhesion behavior with respect to ink has to be enhanced. To achieve this, wide range of surface treatment techniques including chemical, flame, corona discharge and plasma are available. In this study we had polyethylene bottles which are used for packaging and they are usually printed to be informative for consumers. Some of the PE bottles were treated by chemical etching and some by flame. In flame method, conveyor belt speed, and flame distance were variable. Screen method was used to print the treated bottles. Adhesion of these bottles was measured by tape test and cross-cut. At lowest distance (3cm) by reducing the speed, the adhesion was increased. Adhesion reached an optimum for 6cm and 12cm and then it decreased because of the over treatment.
