Development of heat shrinkable BOPP packaging film with low friction coefficient
A high-performance biaxially oriented polypropylene(BOPP)film was developed using a special raw material formulation with a special processing technique,and its friction coefficient,heat shrinkage,and optical properties were compared with a standard BOPP film at four selected times on the 1st,7th,15th,and 30th days within 30 days.The re-sults indicated that the developed film obtained an improvement in all aspects of performance.The film exhibited a low friction coefficient,high heat shrinkage,and excellent optical properties.
