Ahlstrom, a global frontrunner in sustainable fiber-based solutions, has expanded its well-regarded LamiBak™ portfolio with the launch of LamiBak™ Flex — a new base paper specifically engineered for flexible food packaging. This addition marks a strategic development for converters and brand owners looking to move away from plastic- and foil-based substrates without compromising on performance, regulatory compliance, or consumer appeal.
The global shift toward more circular packaging systems has intensified pressure on the food packaging industry to deliver materials that support both environmental targets and functional requirements. Ahlstrom’s LamiBak™ Flex addresses this dual challenge by offering a high-performance paper-based solution that enables sustainability from sourcing through end-of-life, while maintaining the versatility required for complex packaging applications such as pouches, sachets, and flow wraps.
Sustainability at the core
LamiBak™ Flex builds on Ahlstrom’s deep-rooted commitment to environmental responsibility. The base paper is made from 100% responsibly sourced wood pulp, holding either FSC® or PEFC™ certifications, which guarantees that raw materials are derived from sustainably managed forests.
This product complies with paper recyclability standards in Europe under EN 13430 and CEPI protocols, and it is designed to be compatible with U.S. recycling standards and has specifically passed Part 1 of Western Michigan’s repulpability test method Additionally, it meets the criteria for industrial compostability in several regions, offering further flexibility in waste management strategies.
A key feature that sets LamiBak™ Flex apart is its PFAS-free composition. As regulatory bodies across the globe move to restrict the use of the so-called “forever chemicals” (PFAS), Ahlstrom’s proactive formulation helps converters stay ahead of compliance demands.
By integrating recyclability, renewable sourcing, and chemical safety, LamiBak™ Flex enables packaging producers to support a more sustainable value chain while maintaining the material integrity needed for food-contact applications.
Performance Without Compromise
While its environmental attributes are significant, LamiBak™ Flex is equally defined by its high-performance profile. Engineered for flexibility, the base paper serves as a conversion-friendly platform suitable for further processing techniques, including extrusion, coating, and metallization. This adaptability allows packaging converters to tailor the final barrier properties according to the product requirements.
One of the paper’s notable performance features is its ability to reduce the need for excess primer or barrier coatings. This not only streamlines the converting process, saving time and cost, but also has the potential to improve recyclability and lower the material footprint — further supporting the product’s overall sustainability credentials.
With its tailored made paper-based structure, LamiBak™ Flex offers excellent mechanical strength and runnability, ensuring smooth performance on packaging lines and consistent results across various packaging formats.
Shaping the Future of Food Packaging
Ahlstrom’s launch of LamiBak™ Flex reinforces its role as a proactive innovator in the sustainable packaging space. By delivering a paper solution that balances functional, environmental, and economic priorities, the company supports brand owners and converters in achieving both regulatory readiness and consumer trust.
As global expectations continue to shift toward transparency, safety, and environmental stewardship, LamiBak™ Flex presents a timely and forward-thinking solution. It helps bridge the gap between performance-driven design and planet-positive action — a critical intersection for the future of packaging.
