For reducing the breakage during transmission process, BOPP cigarette packaging requires perfect tensile strength. Generally, 140N/mm2 vertically and 200N/mm2 crosswise are required. Elongation rate is for analysis of incision easiness of films. Cigarette packaging industry is different from other industries. Higher elongation rate is not better. Max. limitations of 200% vertically and 80% crosswise can [...]
