摘要： New C2C3 random copolymer (RACO), which shows improved sealing behaviour due to low sealing initiation temperature (SIT) and high hot tack force. In addition, the inventive C2C3 random copolymer (RACO) shows an excellent sterilization behaviour, i.e. retention of low haze level after sterilization. The present invention is furthermore related to the manufacture of said C2C3 random copolymer (RACO) and to its use.
