Two More LLDPE Families for High-Performance Blown Film
Two new families of “enhanced” hexene-copolymer LLDPE resins for blown film are said to offer excellent impact resistance and outstanding hot-tack and heat-seal properties. One resin family reportedly can replace high-end octene LLDPE while the other is said to equal or surpass the performance of VLDPE or metallocene LLDPE (mLLDPE).
