Release Liners are carriers of many PSA labeling materials, allowing highly efficient printing, cutting, and application of PSA labels.

Ahlstrom, a global name in combining fibers into sustainable specialty materials, is extending its range of release papers by introducing new products supporting sustainability and circularity in manufacturing pressure-sensitive adhesive (PSA) laminates and labels.

Ahlstrom says it strives to develop sustainable products, support the transition to more renewable, bio-based materials, and enable more efficient use of resources.

Release Liners are carriers of many PSA labeling materials, allowing highly efficient printing, cutting, and application of PSA labels. While performing a sustainable function, as they contribute to reducing product waste, increasing product safety, and moving goods reliably and efficiently through traditional or online distribution, they can also be manufactured with increasingly sustainable components.

In line with these targets, Ahlstrom says it is extending its Acti-V range of high-performance label release liners with new products offering novel options to sustainability-driven laminators, label printers, and end-users, thanks to the use of post-consumer recycled fibers and unbleached cellulose fibers:

  • Acti-V RF Yellow is a supercalendered release paper including at least 15% post-consumer recycled fiber, featuring the typical light-yellow color of paper liners that carry most PSA paper labels in Europe.
  • Acti-V RF Natural is a supercalendered release paper featuring a light creamy color, naturally resulting from the blend of at least 15% post-consumer recycled fiber and unbleached and bleached cellulose fibers.

Both products support circularity by replacing a portion of virgin fibers with post-consumer recycled fibers. Additionally, the new Acti-V RF Natural does not use any dye and is based on components that – according to Ahlstrom’s initial estimates – can allow reduction of at least 15 % in the carbon footprint compared to the standard Acti-V Yellow liner. 

The new release papers maintain the outstanding performance of Ahlstrom’s proprietary Acti-V technology, which allows a highly efficient silicone coating and converting process, showing potential reductions in the consumption of energy, catalysts, and silicone.   

To help increase circularity in the labeling industry, Ahlstrom was one of the founding members of CELAB (Toward a circular economy for labels), the industry coalition dedicated to building a sustainable self-adhesive labeling industry and creating greater circularity by enhancing and promoting matrix and release liner recycling worldwide.

With manufacturing in Europe and the Americas, the proven track record of its Acti-V and trulyNatural  technologies as well as its expertise in the use of post-consumer recycled fibers, Ahlstrom says it continues its pioneering innovation journey in release liners and is well positioned to bring to the market increasingly sustainable products, working side by side with the labeling industry and other sustainability-driven sectors worldwide.

New release liners

Earlier in July, Ahlstrom had introduced new products that support the design of more sustainable double-sided PSA tapes.

An extension of Ahlstrom’s Acti-V® Industrial dedicated range of high-performance release liners, the products offer novel options to support environmentally conscious tape producers, thanks to the use of post-consumer recycled fiber, and unbleached cellulose fibers:

  • Acti-V Industrial RF Brown is a supercalendered release paper including 30% post-consumer recycled fiber, and featuring the typical brown color used in double-sided adhesive tape liners`
  • Acti-V Industrial RF Natural is a supercalendered release paper featuring a natural kraft color, based on a combination of post-consumer recycled cellulose fiber (at least 15%) and unbleached cellulose fibers.

Packaging South Asia — resilient, growing and impactful — daily, monthly — always responsive

The multi-channel B2B in print and digital 17-year-old platform matches the industry’s growth trajectory. The Indian, South Asian, Southeast Asian, and Middle East packaging industries are looking beyond the resilience of the past three years. They are resuming capacity expansion and diversification, with high technology and automation in new plants and projects.

As we present our 2024 publishing plan, India’s real GDP growth for the financial year ending 31 March 2024 will exceed 6%. The packaging industry growth will match the GDP growth in volume terms and surpass it by at least 3% in terms of nominal growth allowing for price inflation in energy, raw materials, consumables, and capital equipment.

The capacity for flexible film manufacturing in India increased by 45% over the past four years. With orders in place, we expect another 20% capacity addition in 2024 and 2025. Capacities in monocartons, corrugation, aseptic liquid packaging, and labels are growing similarly. As the consumption story returns over the next six months, we expect demand to return and exceed the growth trajectory of previous years. The numbers are positive for most of the economies in the region – and as shown by our analytics, our platform increasingly reaches and influences these.

For responsible and sustainable packaging, with its attendant regulations and compliances, there is significant headroom to grow in India and the region. Our coverage includes the entire packaging supply chain – from concept to shelf and to waste collection, sorting, and recycling.

We target brand owners, product managers, raw material suppliers, packaging designers and converters, and recyclers. This is a large and complex canvas – the only thing that can work is your agile thinking and innovation together with our continuous learning and persistence.

The coming year looks to be an up year in this region, and this is the right time to plan your participation and marketing communication – in our rich and highly targeted business platform with human resources on the ground. Share your thoughts and plans to inspire and mobilize our editorial and advertising teams!
