Research on the Performances of Heat-Sealing BOPP Film: Influence of coating thickness

摘要

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 high-performances. Therefore, an effective research 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.
