POLYPROPYLENE RESIN COMPOSITIONS |
摘要 |
Polypropylene resin compositions suitable for producing polypropylene films with excellent properties are disclosed. The compositions can provide polypropylene films having very excellent transparency, excellent heat-sealability and good anti-blocking property. Such characteristics are essential requirements for packing films. The polypropylene resin compositions comprise 70 to 99 parts by weight of polypropylene and 1 to 30 parts by weight of a specific hydrogenated petroleum resin. The hydrogenated petroleum resin can easily be prepared industrially from valueless by-products of oil and petrochemical industries, such as C5 fraction and C9 fraction by-produced in naphtha steam cracking process.
