Colours Americas launched a range of bio-derived colorants developed for use with PET and biopolymers used in cosmetic and personal care packaging, as well as other applications. “Today’s consumers expect eco- friendly packaging material to break down com- pletely, including the colour components,” says Lydia Swan, Sales & Marketing Manager, Holland Colours Americas. The Natural Collection uses non-petroleum based pigments and a bio-derived carrier that is compatible with resins such as PET, PLA, and PHA. The company’s PET concentrate carrier has traditionally been petroleum-free, but the new line also uses petroleum-free pigments.

Despite the focus on new colours and effects, black retains its attraction and most especially the lacquer-like “piano black” is the latest generation of black
masterbatches from Germany-based Grafe. Designed for use with PE and PP resins, Black3
is said to yield an extremely intense
depth of colour that can be easily adjusted to produce the required depth setting. “In the area of packaging, the colour
black represents exquisite and modern products, symbolising strength and stability. Our new Black³, with its incredible depth of colour, provides a clear contrast to the previous black batch and presents a range of products in an amazing color
intensity“, explains Julia Canzler, Design & Packag- ing at Grafe Group. The Black3
masterbatch is
suitable for injection moulding and extrusion processing and can be used where both matt or high gloss
surfaces are required. The company says the products comply with all relevant standards for cosmetics packaging industry applications.
Options for PVC Clariant’s latest pigment preparation for soft and rigid PVC, Telasperse PVC, is based on organic pigments and incudes white and black grades. The product does not contain phthalates and is available in free-flowing, low-dusting powder or granular forms. Selected grades are compliant with food contact regulations. It is intended for colour- ing of film and sheet, profiles, fences, cables, and toys made of plasticised or unplasticised PVC. Due to the pigment’s good dispersion characteristics, the company says full colour strength can be obtained and processing time is reduced. Low dust levels contribute to a cleaner working environment.
