In addition, its Sicolen Eco and Sicoversal Eco
grades also have bio-based carriers. They are made from renewable resources, offering an eco-friendly alternative to fossil-based products without compromising on performance. The company also offers Sicolen R with a

UV barrier for food Ampacet has introduced a new UV barrier master- batch for food and industrial packaging. It says that UVBlock 1496 offers a sustainable
alternative to conventional UV solutions based on benzotriazole additives. Light exposure, especially UVA and UVB, can damage food components such as fats, proteins and vitamins. Photo degradation can cause discoloration, off-flavours and odours and, ulti- mately, food waste. Non-food products can also degrade under UV exposure. To protect these products from UV degradation, UV barrier additives are often added to packaging. Ampacet says that UVBlock 1496 is formulated without the intentional addition of substances of very high concern (SVHCs). It offers superior optical properties and good UV barrier performance in the low UVA and UVB wavelength range. In addition, it is approved for food contact applications in Europe and the U.S. Conventional UV additives containing phenolic benzotriazoles have faced regulatory pressure due to environmental concerns, with some grades added to the European ECHA candidate list of SVHCs.
Green masterbatch At Fakuma last year, Sun Chemical showed a number of its sustainable masterbatches. Its Sicoveral B biodegradable masterbatches are designed to reduce environmental impact, with bio-degradable carrier systems that are aimed at applications requiring a shorter lifecycle.
recycled carrier. These masterbatches maximise the recycling content in the final product, contributing to a circular economy, it says. “Our range of technologies and our ability to
innovate in response to market trends sets us apart,” said Kai Sörensen, director of business management for colour materials at Sun Chemical. “This, combined with our broad portfolio capabili- ties, makes us the ideal technological partner.” More recently, the company showed a range of
grades for plastics recycling at Chinaplas. These included Sicopal Black K 0098 FK, which has heat stability, global food contact compliance (including China GB 9685). It has been adopted in food packaging in place of carbon black to enable thorough waste-sorting. It also displayed Microlen Blue 7460 Eco, which is certified by EN 13432 and designed for bio-compostable plastics – adding to colouring options between PCN green and blue.
Film star Film producer Charter Next Generation (CNG) has expanded its GreenArrow portfolio with a new line of cavitated polyethylene (PE) films – which were developed using a masterbatch from Void Technologies. The new films, which meet growing demand for
flow wrap and confectionery applications, use Void’s patented VO+ PE voiding agent masterbatch combined with machine direction orientation (MDO) film processing. The film structures are opaque yet compatible
with existing PE recycling streams, making the packaging suitable for recycling. Using VO+ masterbatch, CNG can produce
