Welcome black! Clariant launches NIR-detectable black colorants for a wide range of recyclable polymers at K 2019

(Photo: Clariant)Clariant gives the recycling potential of black plastics a much-needed boost. At K 2019, it will launch the first range of near infrared (NIR)-detectable black pigments and dyes applicable to a wide variety of recyclable plastics. The extension adds another step in the right direction addressing the sorting challenge of high-appeal black packaging for recovery and recycling facilities.

Clariant partners with Merck & SABIC to perfect laser marking of flexible packaging

Clariant partners with Merck & SABIC to perfect laser marking of flexible packaging. 
(Photo: Clariant)Clariant has teamed up with pigment supplier Merck KGaA and resin producer SABIC to develop laser-marking technology and materials to ease the recycling process for flexible polyethylene (LDPE, LLDPE) packaging film. The results of the collaboration will be presented at K 2019, the international plastics trade fair being held on October 16 to 23 at Messe Dusseldorf in Germany.

ChemCycling™ sources feedstock from post-consumer plastic waste to produce virgin grade material for food contact approved quality.

Together they produced a stand-up pouch that is safe for food contact partly made with raw material which was derived from chemically recycled plastic. Until now, recycling plastic has chiefly been mechanical, limiting the scope of plastics that can be recycled and limiting the number of products that can be created with recycled material, in particular for the strict legal European regulations in place for food packaging.

Clariant advances a colorful future for biodegradable plastics

A colorful future is in reach for biodegradable plastics. Clariant brings it even closer with the launch of a range of 25 organic pigments for biodegradable and compostable polymers which are compliant with the European Norm 13432 opening up color options and the appeal of organically recyclable packaging.

Clariant HYDROCEROL® CFA Masterbatches Cut Plastics Content in Packaging by 10%

Clariant HYDROCEROL CFA Masterbatches Cut Plastics Content in Packaging by 10%. (Photo: Clariant)Packaging manufacturers and brand owners trying to reach sustainability goals and reduce costs are expressing keen interest in the newest HYDROCEROL chemical foaming agents (CFAs) from Clariant’s Masterbatches. The finer and more durable foam-cell structures make it possible to cut resin use and reduce part weight – without significant loss in mechanical properties.

Clariant Additive Masterbatch Makes Black Plastic Packaging ‘Visible’ to Sorting Systems

Tests on high-density polyethylene (HDPE) also showed positive results (see graph). HDPE with CESA-IR shows a curve similar to the uncolored HDPE curve and distinct from the LDPE curve and allowing for easy separation. PET and C-PET sheet and film were also tested by TOMRA Sorting Recycling, with similarly positive results. 
(Graph: Clariant)New Clariant CESA®-IR additive masterbatches are now available to make dark-colored plastics visible to the near-infrared (NIR) sensors used in automated polymer sorting systems. While many companies use black packaging to brand their prestige products, the problems it poses in recycling systems has led to calls for black to be phased out of the palette. The new masterbatches help to resolve that issue and allows increased recycling rates in Europe and elsewhere.
