Milliken’s clarifier-colourant combo gets the thumbs up from Thumbs Up

One of Thumbs Up’s prime requirements has always been the clarity of the finished product which is being achieved by working with Milliken and the major resin producers. But it was the trials using an innovative range of random copolymers formulated with Millad NX8000 at Enhanced Quality that, he says, “gave us not only further enhancements in clarity, but also production cost savings.”

Explaining Thumbs Up’s decision to use ClearTint together with Millad NX8000, John McGuinness says: “Our own consumer research and discussions with major retailers related to our ‘in mould’ decoration process indicated that we needed to look at tints that would not negatively affect the advantages of the new clarified material, but would help further increase the consumer appeal of the containers.”

ClearTint polymeric dyes are the perfect complement to Millad NX8000. Unlike more conventional dyes, they are non-extractable and suitable for food contact applications. Nor do they affect part shrinkage, which can be a problem with pigments often used in polyolefins.

John McGuinness says the positive reaction from his potential customers when they saw prototype containers meant that choosing the new PP/NX8000/ClearTint combination was a simple process. The company has since begun production of containers ranging from 0.6 to 150 liters in a variety of colours for one major retailer. Strong interest from others is likely to be turned into hard orders for the domestic storage boxes and towers in the next few months.

John McGuinness concludes: “I am certain that our cooperation with Milliken will help create a new market for us and enable the major retailers to see the commercial advantages that come with offering consumer design-led merchandise incorporating the latest colour trends. We envisage that demand for random-copolymer containing Millad NX8000 coupled with the Milliken ClearTint colours will grow substantially in the next twelve months.”

A new line of food and domestic storage containers in coloured polypropylene random copolymer compounds that provide unparalleled clarity. The compounds contain Milliken’s ground-breaking Millad NX8000 clarifying agent, used in combination with the company’s ClearTint polymeric dyes.
