Sinopec is the largest BOPP resin supplier in China. The company has made a breakthrough in the theoretical research on BOPP. Starting with the design and control of the molecular structure of polypropylene, Sinopec has overcome a series of technical challenges such as tensile and thermal stability, and significantly improved the quality of its BOPP resin. The linear velocity could exceed 400 meters per minute during film processing.
BOPP is mainly used in the production of high-stiffness, high-transparence packaging film. It is also widely used in the production of printing and laminated film, Matt film, pearlized film, synthetic paper, cigarette film, etc.
