Mondi, a global leader in sustainable packaging and paper, has announced a significant expansion of its MailerBAG production capacity. The company’s latest investment targets the growing demand for environmentally friendly eCommerce packaging, particularly paper-based alternatives to traditional plastic mailers.

The expansion, which enhances capacity at multiple European sites, reflects Mondi’s commitment to delivering scalable, sustainable packaging solutions for the booming online retail market. As eCommerce continues its upward trajectory, so does the environmental scrutiny over packaging materials. Mondi’s MailerBAG, a paper-based mailer that is recyclable and renewable, offers an eco-conscious alternative designed to replace plastic poly mailers.

MailerBAG: Designed for Function and Sustainability

Available in multiple formats—including peel-and-seal closures and padded options—the MailerBAG is tailored to meet various retail needs while maintaining high levels of durability and product protection. The expansion includes investments in machinery and process optimization to improve production efficiency and increase output without compromising quality.

“This expansion helps us support our eCommerce customers on their sustainability journey,” said Marko Schuster, COO of Mondi's Functional Paper and Films division. “By increasing MailerBAG capacity, we are directly addressing market needs and enabling the transition away from single-use plastic packaging.”

Strategic Response to Market Dynamics

The growth in online shopping has resulted in massive packaging volumes. Regulatory pressures, corporate ESG commitments, and consumer expectations have all catalyzed the shift toward more sustainable packaging formats. Mondi’s MailerBAG, which is designed for easy recyclability in existing paper streams, supports these objectives and aligns with global efforts to reduce plastic pollution.

This expansion also positions Mondi to better serve major eCommerce retailers and logistics providers seeking scalable, eco-friendly packaging. With enhanced supply capabilities, the company aims to reduce lead times and improve regional distribution efficiency.

Looking Ahead: Innovating at Scale

The MailerBAG is part of Mondi’s wider EcoSolutions approach, a strategy that focuses on replacing unsustainable materials with fit-for-purpose alternatives. The company continues to invest in R&D to enhance material performance, reduce weight, and improve printability—key factors for brand-conscious online retailers.

By bolstering its MailerBAG production capacity, Mondi reinforces its role as a key player in the transition to a circular economy for packaging. As more countries move toward banning certain single-use plastics and as eCommerce continues to dominate retail, paper-based mailers like MailerBAG are set to become industry standards.

For consumers and brands alike, the message is clear: sustainable packaging isn’t just a trend—it’s a necessity. And companies like Mondi are stepping up to meet that demand with innovation, investment, and a clear vision for a greener future.
