The newest grade in the Vistamaxx metallocene-catalyzed specialty olefinic TPEs from ExxonMobil Chemical is designed for high-performance cast power pre-stretch (PPS) films and makes its debut here at NPE.


            When used in the functional layer of cast PPS films, Vistamaxx 6000 is said to provide outstanding ultimate stretch, excellent holding force and tear propagation resistance even at thin gauge. This reportedly contributes to the secure transportation of goods, while helping to reduce waste and cost from damaged products.


            “Although the functional layer of stretch film comprises only about 10-15 percent of the total film composition, the intrinsic properties of the material used in that layer are key to performance. Vistamaxx 6000 has been designed to improve stretch film performance in response to market trends,” says global development manager Bill Ramsey. One such trend is the emergence of more mechanized and automated logistics chains, and the growing use of pallets to transport goods. Cost-efficient logistics operation can be made possible by combining the advantage of high-performance films and high-speed wrapping equipment,


            End-users are also moving to higher stretch or thinner gauge high-performance films, which can ultimately result in less film weight for the same pallet stability. “In the functional layer of cast PPS films, Vistamaxx combines high stretch with high holding force, exceptional toughness and easy processability for high output. It creates a very versatile film that adds value for both the extrusion and wrapping operation,” says Ramsey.


            European stretch film producer Ergis S.A., with a market presence in the PPS segment, has been running Vistamaxx 6000 in the functional layer of a high-performance PPS film. “We are impressed by the film’s excellent processability. Vistamaxx 6000 demonstrates flow right to the edges of the die resulting in excellent web stability and film roll appearance. Also, the film’s properties—ultimate stretch, stretch force and puncture—measured at 300% pre-stretch, were outstanding. The excellent tear propagation resistance provided by Vistamaxx 6000 clearly enables smooth, high-speed wrapping operations,” says Ergis’ managing director Grzegorz Kedzierski.
