UPM Specialty Papers and Henkel create a sustainable heat-sealable packaging concept delivering unrivalled levels of grease resistance

Working closely with partners from across the food packaging value network, UPM Specialty Papers is co-creating transformative solutions that reimagine the future of sustainable packaging. A long-standing relationship with Henkel, a worldwide leader in industrial and consumer businesses, has now resulted in a recyclable, heat-sealable packaging material compatible with existing packaging lines. Pushing the performance of barrier papers to an unsurpassed level of grease resistance, it offers a tried and tested concept for converters.

Reinventing the seal
The plastic coating traditionally required for protection and heat-sealing renders the final product difficult to recycle. Inspired by a shared focus on creating sustainable alternatives, UPM Specialty Papers and Henkel have reinvented the concept to help brand owners and converters meet ever growing consumer and regulatory demands for easy to recycle packaging.

“In line with our 2030 sustainability ambitions, our water-based LOCTITE LIOFOL HS 2809-22 RE heat seal and AQUENCE EPIX BC 6134 grease barrier coatings are easy to recycle, helping to recover more fibres and supporting a more circular economy. Together with UPM Specialty Papers, we have moved one step closer to bridging the gap between sustainable fibre-based packaging and traditional plastic packaging to support brand owners and converters in the transition to paper,” says Christin Noack, Market Strategy Manager Paper Solutions at Henkel.

Progress through partnership
Existing UPM Asendo™ and UPM Asendo™ Pro barrier papers provided the starting point. These recyclable barrier papers are produced with fibres from sustainably managed forests and offer grease and moisture resistance without the need for a plastic coating.

The partnership then set out to push the limits of performance to create food-safe, heat-sealed, paper-based packaging that can be recycled in existing fibre recycling streams. This is where Henkel’s expertise came into play with the optimization of its pioneering coatings specifically for the UPM papers, reinforcing their original barrier properties to offer unmatched levels of grease resistance.

SPLASHBAG on World Tour – sustainable, water-repellent paper bag receives global recognition

Mondi Industrial Bags, in collaboration with its customer and cement producer LafargeHolcim, has created SPLASHBAG – a paper-based solution designed to satisfy the need of dealing with materials that are often exposed to wet conditions or environments. The product has been developed as a direct response to the customer’s packaging needs in this area, and is suitable for the protection of moisture-sensitive filling goods, including building materials, chemicals and pharmaceuticals. Having successfully launched in Europe, the product is now gaining traction in many other markets around the world. Based on Mondi`s Advantage Protect sack kraft paper – a grade that offers both a water-repellent surface and high wet tensile strength – the bag maintains high strength even in wet environments. Thanks to its bespoke benefits, within the last year SPLASHBAG has quickly gained global recognition – from Azerbaijan and Bulgaria to France and La Réunion. The key to SPLASHBAG‘s success lies in its enhanced sack kraft paper properties – absorbing less moisture than conventional paper bags and maintaining both integrity and product quality.

UPM Raflatac announces further progress towards the Ellen MacArthur Foundation and UNEP’s New Plastics Economy Global Commitment

UPM Raflatac announces great progress toward a more circular economy for plastics and a future beyond fossils. This progress is detailed in the New Plastics Economy Global Commitment 2021 Progress Report by the Ellen MacArthur Foundation and the UN Environment Programme (UNEP). As highlighted in the report, UPM Raflatac has continued to develop its SmartChoice™ and SmartCircle™ product ranges and increased the sales volumes of these products. SmartChoice label materials are designed to reduce material usage and promote the use of recycled content and renewable materials. SmartCircle label materials support packaging recyclability and reuse and so promote the circular economy. Reducing unnecessary plastic packaging is a priority for UPM Raflatac, and through raw material optimization, it has reduced more than 450 tonnes of plastic film raw materials. UPM Raflatac has signature products, e.g., PP Lite, that have a strong reduce element, but it is also applying the reduced principle to its standard films. In addition, the company supports the switch to renewable materials by enlarging and promoting its RAFNXT+ product range, as well as bio-based plastic product range.
