Industry News Clariant helps packaging customers improve quality of recycled polymers
Recognising that recycling is the foundation of a circular economy, Clariant Masterbatches and its packaging market group, is mobilising considerable resources to help ensure that a high percentage of plastic packaging is recycled. Alessandro Dulli, Clariant Masterbatches global head of packaging says, “We can
recover – we must recover – much, much greater volumes and turn the vast amount of packaging waste into new raw material. To do that, we need to overcome major challenges around the capabilities of proper sorting of waste to produce a high-quality PCR [post-consumer recyclate], and around issues related to coloration, stabilisation, product safety and process stability.” Clariant has begun establishing a dedicated team to understand these dynamics and
reduce these risks, to remain at the forefront of products and technologies that increase the quality of PCR. Already, substantial resources are available in the form of new and existing additive and colorant technologies that include products that prevent damage or loss of performance properties during recycling and others that actually repair damage that inevitably occurs as polymers are processed, used and then reprocessed. This includes antioxidants – The combination of heat and exposure to oxygen can cause plastics to lose
mechanical properties or become discoloured, and black spots can form. Any of these can render the material unsuitable for re-use. Clariant CESA-nox antioxidants, added during PCR compounding or the production of new packaging made from recycled material, prevent these problems. The other damage preventions are the new processing aids – The melt behaviour of PCR polymers differs from that of virgin material, which leads to a higher
risk of build-up around the die, where it can degrade and become discoloured. CESA-process additive master-batches effectively reduce this effect and provide for smoother processing.
DTM Group to cooperate with OKI
Graham Packaging receives sustainability award
Graham Packaging, a leader in the design and manufacturing of innovative and sustainable plastic packaging solutions, was recently honoured with a 2019 Sustainability Award from the Business Intelligence Group in the Sustainability Leadership (Organization) category. Graham was the only packaging company to receive an award in this category. Other recipients included Bridgestone Americas, Gulfstream Aerospace Corporation and The Johns Hopkins University, School of Medicine. “Since its founding nearly a half century ago, Graham Packaging has consistently looked for
ways to be more sustainable through innovative packaging solutions and industry-leading recycling efforts,” said Mike King, chief executive officer, Graham Packaging. “This award shines a light on our ongoing efforts in supporting a circular economy.”
DTM Group has added OKI’s Pro1050 digital LED five colour label printer to its product portfolio to be distributed through its subsidiary DTM Print (formerly Primera Europe). Working closely with OKI Europe, DTM Group will make the device available through its distribution channels in Germany, Switzerland, Austria, Spain, Portugal, Ireland and the CEE region. With its expertise and experience in the range
of digital label printers, the company has contributed significantly to the success of Primera Technology's LX- and CX-Series Color Label Printers in the EMEA region. OKI’s Pro1050 Label Printer is based on LED
technology, can print in five colours (CMYK + W) and handles medium to large runs of colour labels on demand. With the unique fifth colour option “white”, the Pro1050 sets new standards in creativity in its class. In addition to the roll-to-roll printing option, the integrated cutter allows the output of handy label stacks.
Metsä Board’s FBB printed samples highlight recent packaging trends
To demonstrate how paperboard can boost brand appeal, Metsä Board has launched a new set of packaging samples. The samples demonstrate the various finishing effects and how the paperboard surface can enhance them and create impressive visual and tactile effects. The samples have been designed to inspire end-users in sectors such as food, beautycare, pharmaceuticals, luxury packaging and graphic applications. The samples are produced using the enhanced Metsä Board folding boxboard portfolio. The organic cosmetics sample has an uncoated surface with a multilayer embossing that give a special touch and feel. White and gold hot foil stamping adds a luxurious finish to the packaging. The chocolate sample also uses a multilayer embossing with a metallic appearance added to the CMYK printing on silver PE laminate in the text area. The most demanding sample is the headset packaging that combines various effects requiring
many features from the paperboard. The cover of the box is first hot-foiled, then printed with white and CMYK, and finally a multilayer embossing were added to give touch and feel. On the front of the packaging there are tone changes made with grey drop shadows. On the side of the box there is a silver hot-foil in the background with CMYK printing combining micro-embossing, a multilayer embossing and a debossing.
