used at 100%, it affects the colour of the packaged article,” he says. Colour and effect additives can be used to help
correct aesthetic issues in recycled plastics. For example, Cotton says the company’s “aged glass” effect masterbatches used in rPET can “upcycle the polymer, making it appear cleaner, albeit translu- cent instead of transparent.”. Natural materials can also be used to create a
recognisable, sustainable effect. In 2021, Colloids launched its patented line of BeaNused master- batches, which contain up to 30% used coffee grounds. “The R&D team developed a range of colours that are enhanced by the different colour flecks from the larger coffee flakes. Using these materials adds sustainability to plastic products and it is easily identified by consumers as being made with recycled content,” says Cotton. The New Aesthetix initiative at Avient involves a
team working on specific projects intended to meet industry needs for aesthetic effects in thermoplastics that cannot be met by the conven- tional development route, says Daniele Conti, Polymer Scientist, New Aesthetix. The company says the team, which is part of Avient’s global ColorWorks network, combines polymer science with “creativity and unconventional ways to look at processing and formulation.” An example New Aesthetix development is the

Toukelín effect, which creates natural-looking gold or black speckles in virgin and recycled polyolefins and styrenics. Another is the Tschùmbia! effect, which is a discrete multicoloured confetti effect for injection moulding of polyolefin or TPO parts. “Tschùmbia! can contribute to answer the growing demand of the product designers for non-homo- geneous colouration solution, which traditionally poses multiple challenges to converters,” says Conti. The team is currently studying applicability of the effect in styrenic polymers and PC.
Effective forecasting Two of the confetti effects are featured in Avient’s latest colour forecasting guide for the plastics industry — ColorForward 2023. Created by the Avient ColorWorks team, Conti says the guide presents “four global trend stories that capture the emotions that can be expected to influence consumers’ response to colour over the next few years … to help plastic product designers and marketing professionals make more informed colour choices for new products and packaging.” One of the colours in ColorForward 2023
incorporating the Tschùmbia! effect is Todes nosotres, a transparent pink/red combined with multicoloured particles. The colour represents “equality and unicity”and is one of the five colours belonging to the theme Catalyst. This puts the focus on Generation Z and other young genera- tions, on their acute fears for the future and on their push for action on a whole range of issues that will shape the world,” according to Conti. The Cybertschumbia effect is a plain white colour that changes to speckles of light under UV light. It is part of the theme “Meet-your-verse, which opens the doors to the exploration of the unchart- ed metaverse,” says Conti.
