Black polymer visible to NIR

Additive and masterbatch manufacturer Colour Tone has launched a new generation of near-infrared (NIR) detectable masterbatches to satisfy recyclability concerns for problem single-life black plastic tubs, trays and films.

The first two black masterbatches from this latest colouring system are developed for polypropylene applications, but can be applied to any other polymer.

The 958884 masterbatch satisfies EU food contact legislation and is available at an economic 0.21p per tray. This is said to represent a substantial 60% price saving compared with the costs quoted in WRAP’s first commissioned project to commercialise this technology.

The 95893 masterbatch supports applications required to meet the US Food and Drugs Administration code, benefitting companies that supply to US markets.
