Basell has launched a new metallocene-based Metocene polypropylene (PP) copolymer, Clyrell EM248U, to target processors of clear, thin-wall, injection-molded (TWIM) food applications in the United States.
According to the company, the grade is produced using an exceptionally clean technology with low levels of volatiles and oligomers. It is a reactor-grade product which does not require vis-breaking or peroxides, and can be used in customer food applications which require low organoleptic properties. At a melt flow rate of 70g/10min, the resin offers processing ease with the potential for cycle time reduction without sacrificing part performance. Metocene resins also offer increased resistance to distortion and warpage in injection molding applications.
Clyrell EM248U has been previously targeted to European customers for food packaging applications requiring refrigeration and/or freezer impact performance. It is anticipated that U.S. customers will use the material for refrigerated packaging applications for products such as soups, salads and cut fruits.
