UPM Specialty Papers and partners developed new opportunities for UPM’s packaging papers on standard flexo printing machines

UPM’s barrier and barrier base papers can be enhanced with heat-seal properties while reproducing high-quality images in almost any flexographic print shop under normal production conditions. This was demonstrated in joint co-creation project carried out by UPM Specialty Papers, BOBST, and Siegwerk. The test results verified that it is possible to efficiently print packaging papers and at the same time achieve heat-sealability using flexographic printing techniques.

The project combined a number of UPM’s barrier and barrier base papers with Siegwerk’s water-based ink series UniNATURE, which are formulated with a high Bio Renewable Content (BRC), and two heat-sealing lacquers for paper and board applications from their CIRKIT coatings range. The papers were printed using BOBST MASTER CI, a 10-color wide-web printing press designed for water-based inks and 800 m/min speed.

“Making the transition to fibre-based packaging requires collaboration between packaging value network members. We are eager to explore solutions with partners that support this transition, while taking advantage of existing production methods. Through co-creation with BOBST and Siegwerk, we have successfully developed new opportunities for flexographic printers that can be achieved under normal production conditions,” says Mika Uusikartano, Senior Manager, Product Portfolio Management, UPM Specialty Papers.

Amcor Sustainability Report reflects on landmark year

Amcor released its 2022 Sustainability Report, detailing continued progress against key sustainability metrics and announcing an enhanced target to achieve 30% recycled content across its portfolio by the end of the decade. The new recycled content target, which is three times its previous target of 10%, comes as Amcor reflects on a landmark year for its efforts on sustainability. In fiscal year 2022, the company committed to net zero emissions by 2050, more than doubled post-consumer recycled material purchased since 2019 and achieved a Gold rating from EcoVadis for its industry-leading sustainability practices, placing Amcor among the top 5% of all companies assessed. The Report highlights how Amcor has advanced on its pledge to make all products recyclable, reusable or compostable by 2025, with 74% of total production by weight already designed to be recycled and the number of innovative solutions with more sustainable properties continually growing.

Waddington Europe Starts to Localize ‘Closed Loop’ Packaging in Ireland

Leading European thermoforming packaging specialist Waddington® Europe, a division of Novolex®, has teamed up with Shabra, Ireland’s leading recycler and reprocessor of post-consumer waste (PCW), to purchase food-grade recycled PET (rPET) sourced from bottles, pots, tubs and trays to manufacture new rPET food packaging products at its Arklow production site. Not only does the agreement help to further secure Waddington Europe’s long-term source of rPET, but it also enables the company to expand its line of Eco Blend® products made with post-consumer recycled content sourced domestically in Ireland back into the Irish market. “Collectively, we hope these new agreements will advance our stake in localized plastics circularity in the Irish market,” said Eduardo Gomes, Managing Director of Waddington Europe. “We need to start moving to a more holistic and long-term view when it comes to the lifecycle and environmental impact of food-grade packaging. It’s just as important to consider the carbon footprint at its start of life as the environmental impact at the end of its life.”
