Mondi has launched Ad/Vantage Smooth Brown Semi Extensible, an innovative kraft paper that combines exceptional strength, extensibility, high puncture resistance and a smooth surface. Designed for industrial and consumer packaging applications, the new paper enables reliable protection and efficient converting while ensuring excellent printing and coating performance.

Positioned between traditional sack kraft paper and machine-finished kraft paper grades, Ad/Vantage Smooth Brown Semi Extensible has been developed as a high-performance base paper for coated and heat-sealable packaging solutions. Its calendered surface ensures excellent coating coverage and adhesion, while its smooth texture delivers superior printability compared to natural brown papers with rougher surfaces.

The paper was engineered over a three-year development period by Mondi’s kraft paper specialists to provide a balance of mechanical strength, puncture resistance and smooth surface. This makes it particularly suitable for form-fill-and-seal packaging used for sharp-edged or heavy items such as toys, dry food, spare parts and building materials, as well as other packaging solutions.

Made from responsibly sourced fresh fibers, with PEFC or FSC® chain-of-custody certification optionally available, the substrate is recyclable in EU paper recycling streams, verified using the 4EG recyclability evaluation protocol (CEPI test method). The solution is designed to run on existing converting and filling lines, supporting process efficiency and consistent performance.

“Ad/Vantage Smooth Brown Semi Extensible fills a clear gap in the market by combining excellent runnability and high strength with coating-friendly smoothness in one paper. It is ideally suited as a base material for our barrier papers, where a uniform surface is essential to achieving consistent coating performance,” said Sabrina Klösch, technical sales service at Mondi. “This paper is the result of a close collaboration between our technical sales service, R&D and product development — a strong team effort that reflects our commitment to solving our customers’ technical and sustainability challenges.”
