Benefits of PP in Film ApplicationsBenefits of PP in Film Applications

• HIGH TO LOW CRYSTALLINITY

• LOW DENSITY (0.890 to 0.905 g/cm3) (High Yield m2 / kg)

• OIL & GREASE RESISTANCE

• GOOD WATER VAPOUR BARRIER PROPERTIES

• GOOD HEAT RESISTANCE

• GOOD CHEMICAL RESISTANCE

• GOOD CREEP AND PUNCTURE RESISTANCE
