New Plastic for Injection Moulded Packaging Launched in US

Basell is to launch a new resin suitable for use in thin-walled injection moulded (TWIM) food packaging applications.

The metallocene-based Metocene polypropylene copolymer, dubbed Clyrell EM248U, is produced using an exceptionally clean technology with low levels of volatiles and oligomers, Basell says.

The resin is reactor-grade and does not require vis-breaking or peroxides, and can be used in customer food applications which require low organoleptic properties.

Basell's customer project manager of Metocene Amit Gupta says in the past processors have relied on adding plastomers to conventional polypropylene to achieve the required impact and clarity for TWIM applications.

"Although these blends were capable of meeting performance requirements, the use of the plastomer increased costs and added an extra production step," Gupta says.

"On top of that, inconsistencies in impact strength from batch to batch increased the chances of having part breakages."

Gupta says Clyrell EM249U removes the need to add an additional plastomer without reducing the quality of the finished product.

The resin, which was introduced in Europe last year under the name Clyrell EM1791, will be targeted at the US packaging market.
