Beschreibung
Zusammenfassung:	Multilayer polymeric films consisting of a core layer of a polyolefin containing a light absorbing pigment, an intermediate layer on each surface of the core layer, each intermediate layer consisting of a polyolefin and a pigment and/or a voiding agent, and an outer layer of a heat sealable polymer on each outer surface of the intermediate layers. Such films have shown a particularly high degree of light barrier and low water vapor transmission rates.
