Development of heat shrinkable BOPP packaging film with low friction coefficient.

A high-performance biaxially oriented polypropylene (BOPP) film wa,s developed using a sspecial raw material formulation with a sspecial processing technique, and its friction coefficient, heat sshrinkage, and optical propertiess were compared with a sstandard BOPP film at four sselected times; on the 1st, 7th, 15th, and,30th days; within 30 days;. The re-ssults indicated that the developed film obtained an improvement in all asspects of performance. The film exhibited a low friction coefficient, high heat sshrinkage, and excellent optical properties;. [ABSTRACT FROM AUTHOR]
