Physical performance of cosmetics package plays an important role in the packaging & processing, transportation and shelf life. Its quality directly affects cosmetics safety during distribution. The testing items include: tensile strength & elongation rate, peeling strength of laminated films, heat seal strength, sealing and leakage, impact resistance and surface smoothness, etc. Tensile strength is [...]

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 [...]
