Research on the Performances of Heat-Sealing BOPP Film

Abstract

Abstract-Heat-sealing BOPP films are used widely as commercial packages in recent years. However, nowadays there are some obstacles in heat-sealing BOPP films producing, for example the heat sealing strength is relatively low, which makes heat-sealing BOPP films not satisfy the increasing demands of the modern packagings with highperformances. Therefore, an effective reseach on the relationship of the performences of BOPP film and its physical parameters is in great need. In this paper, we tested various performance indicators of heat-sealing BOPP films with different surface coating thickness. The results showed that heat-sealing strength and haze of BOPP films significantly changed with different coating thickness, while the friction coefficient did not change obviously.
