this can impact corporate decision making. We’ve seen instances of supermarkets reducing their use of plastic, even if evidence suggests that the alternative solutions aren’t actually greener.” For some time now, Broadway Colours has been
asking if recycling compatibility should take precedence over brand consistency, particularly for products with a short lifecycle, Barber says. “We know that highly loaded colours can impede the recycling process. Sometimes the greenest thing to do is make compromises on colour in order to support sustainability. Less pigment and higher amounts of PCR won’t lend themselves to perfect- looking packaging. However brands that are happy to feature imperfections have a great opportunity to communicate this positively. They’ll rightly be seen by consumers as leading the sustainability movement in plastic packaging.” He says Broadway Colours’ colour matching suite will be enhanced as part of site upgrades. “It’s perfect for allowing us to educate customers as we can demonstrate our process to them. It works really well when colouring materials with high levels of PCR.”
Natural colours are providing another trend.
“Lately we have seen a lot of demand for granite, and other natural effects,” says Avient’s Reboux. The company has responded with a collection of ten special effects colourants that she says will enable brand owners to create artisanal looks in plastic. Replicating rocks and fibres as well as floral hues, they are formulated using a proprietary process with organic waste materials such as almond shells, glitter flakes, and synthetic fibres. The colourants can be customised in virgin or recycled resins of various types and are said to provide good alternatives to increase a product’s perceived value across many applications including toys, outdoor goods, furniture, and household appliances. The colourants do not impact polyole- fin recycling streams. Ampacet, another major masterbatch maker,
has introduced the Dallol Collection, which it describes as “a masterbatch designed to impart a modern, dynamic vibrancy to injection moulded parts.” The new colour palette is designed for polyolefin applications. “The collection reflects colours emanating from
Africa, offering visual excursions into the fiery depths of volcanos that produce the unique colours indigenous to Dallol, the hottest place on earth inhabited by humans,” says Philippe Hugele, Strategic Business Manager Rigid Packaging. “In the mysterious acid lakes, a colour spectrum can be found that transitions from glacial blue to emerald green, muddy red to mysterious blacks. The fine ash particles dispersed and embodied within the indigenous colours are captured in this collection.” The colours can be customised to support brand messaging.
