June 17, 2025 (press release) –
As sustainability takes center stage in global commerce, businesses are under increasing pressure to reduce their environmental footprint, particularly in their packaging choices. For many, the challenge is clear: how to maintain product protection, logistical efficiency, and customer satisfaction while minimizing the environmental impact of packaging.
As one of the leading European manufacturers of high-performance eCommerce, courier, and security packaging, we have stepped up to meet this challenge head-on. We have just launched a first-of-its-kind product that could redefine the way businesses think about mailers – the Lignin Mailing Bag. Crafted from a mix of one of nature’s most overlooked materials and post-consumer recycled LDPE, it offers a sustainable alternative to traditional packaging.
Developed in Croatian-Swedish collaboration with cutting-edge biomaterial innovators from Lignin Industries AB, this new solution positions Modepack at the forefront of sustainable packaging innovation.
Introducing Lignin: A Natural Solution to a Global Problem

Lignin, often referred to as the “natural glue” that holds plants together, is the second most abundant biopolymer on the planet—yet it has historically been treated as waste in the paper and pulp industry. Thanks to recent material science breakthroughs, Swedish Lignin Industries has managed to transform lignin into a biobased thermoplastic, Renol®, that we at Modepack mix with post-consumer recycled LDPE, resulting in high-performance packaging that offers both durability and environmental responsibility.
Renol® is made primarily from lignin, a natural renewable polymer and a byproduct of forestry and agricultural industries. As Renol® is recyclable as normal LDPE plastics, it is designed to meet growing consumer and regulatory demands for eco-responsibility.
“This is not just another sustainable mailer. It’s a shift in material science that enables a better future for packaging,” says Jure Širić, Managing Director at Modepack. “By using Renol®, we’ve been able to develop a solution that meets the real-world needs of businesses—performance, cost-efficiency, and sustainability—all in one.”
How do Lignin Mailing Bags reduce CO2 emissions?

Lignin Mailing Bags developed using Renol®, a renewable thermoplastic made from lignin, offer a powerful solution for reducing packaging-related CO₂ emissions.
Lignin, a plant-based polymer and byproduct of the forestry industry, is typically incinerated or discarded. By transforming it into functional material, Lignin Industries extend its life cycle and reduce emissions tied to virgin fossil-based plastics.
CO2 emission reductions of up to 60-70% compared to bags made with conventional recycled plastic films are made possible thanks to:
- Replacing fossil-based polymers with renewable feedstocks
- Valorizing industrial waste instead of sourcing new raw materials
- Efficient, scalable production with lower energy demands
- Recyclability through standard LDPE streams, enabling reuse and circularity
The result is a high-performance mailer that delivers significant carbon savings without compromising durability or usability. Modepack’s Lignin Mailing Bags help businesses meet climate goals while adopting a smarter, circular approach to packaging.
Why It Matters?

Across both Europe and the United States, businesses are navigating a complex and rapidly evolving regulatory landscape. From the EU Packaging Regulation to the U.S. Plastics Pact, regulatory frameworks are increasingly aligned with circular economy principles—demanding reductions in single-use plastics, increased recyclability, and more responsible sourcing.
The Lignin Mailing Bag delivers on these expectations by offering:
- Significantly reduced fossil-based plastic content: Unlike traditional mailers, the lignin bag replaces a substantial portion of fossil-based polymers with renewable materials.
- Renewable feedstock: Derived in part from lignin, a natural, plant-based polymer sourced as a byproduct of the pulp and paper industry.
- Designed for recyclability: Compatible with existing recycling systems and easier to process than conventional plastic poly mailers.
- Robust performance: Moisture-resistant, tear-proof, and tested for the rigors of modern courier and eCommerce logistics.
A Vision for a Greener Future

The Lignin Mailing Bag is ideal for online retailers looking to reduce their environmental footprint without sacrificing reliability or customer satisfaction. With increasing pressure from eco-conscious consumers and tighter environmental regulations across Europe and beyond, businesses are seeking packaging that reflects their values. Modepack’s lignin solution meets that need with elegance and efficiency.
Modepack has long been recognized for its commitment to innovation and sustainability. The introduction of lignin-based packaging is a natural progression in the company’s mission to help clients transition to greener operations, without compromising on security, speed, or branding.
“At Modepack, we believe the future of packaging is circular, not linear. The launch of our Lignin Mailing Bag is a major milestone, but it’s just the beginning. We are committed to exploring and investing in biobased materials that reduce carbon footprint and deliver performance,” said Jure Širić, Managing Director of Modepack
Modepack’s Lignin Mailing Bags are now available to order and can be customized for brand-specific requirements. For more information, visit our webshop or contact our Sales team.
