Colour meets sustainability
Finke Hall A4 – Booth 4208
Karl Finke GmbH & Co. KG, a leading producer of high-quality masterbatches and colour solutions, is focusing on sustainability, especially in products with high recycled content and support for design-for-recycling. The company’s latest developments aim to help plastics processors achieve sustainability goals while maintaining vibrant colours.
Finke’s proprietary process allows its Fibaplast masterbatches to be used in polyolefins with a high proportion of recycled material. By encasing recycled cores in a thin layer of virgin material, the full colour spectrum is maintained. The Fibafekt range enables interference colours on dark substrates. The company’s Fibasol liquid colourants are suitable for colouring plastics with high recyclate content. They are claimed to provide independence from carrier materials, high efficiency, and are compatible with most thermoplastics, including those with significant recycled content.
New products from the Fibaplast masterbatch series for laser marking, the Fibatec uncoloured additive batch series with special functions and the Fibaplast NIR detectable black masterbatches help to meet design-for-recycling requirements for plastic packaging. An expansion of the range for laser markings enables dark markings within transparent plastics such as PET, PC or PMMA and coloured laser markings in many colours and shades on black, carbon black-coloured plastics.
Fibatec is a new uncoloured additive batch series with special functions based on various carrier polymers. The Fibatec UVA additive batches is claimed to provide plastic products with UV protection. This enables the production of colourless bottles for the food and cosmetics sectors. The additive batches are free of benzotriazoles, PAAs and PAHs and contain neither CMR substances nor SVHCs and comply with the regulations for food contact plastics in the EU, the USA and China. They are approved for packaging and registered according to REACH and in the corresponding chemical inventories in the USA and China. The Fibatec UVA additive batches are available on the basis of bottle-grade PET or rPET, among others.
Finke also has developed a Fibaplast NIR detectable black masterbatche to improve the sortability of packaging waste using NIR systems. The formulation contains no carbon black pigments so that even black plastics are easily detected during sorting in NIR systems.
