Abstract

Nowadays heat-sealing biaxial oriented polypropylene (BOPP) films are widely used as packages because of its size-stability and nontoxicity. However, the heat sealing strength is relatively low, which makes BOPP films not satisfy the increasing performance as the modern packagings. Therefore, an effective research on the relationship of the properties of BOPP film and its physical parameters is in great need. In this paper, we tested heat-sealing strength of BOPP films with different surface coating thickness and with different compositions. The results showed that the heat sealing strength of BOPP films increased continuously and slowly with increasing temperature. At the same heat sealing temperature, the heat sealing strength significantly changed with the coating thickness. From random copolymer to mixture, the range of suitable heat sealing temperature gradually increased.
