Solenis and HEIDELBERG Collaborate To Develop Print-Applied, Eco-Friendly Barrier Coatings for Paper Packaging

Mondi has partnered with Adelaide Brighton Cement and Pope Packaging on the development of a new water-resistant paper bag called ‘Rain Barrier,’ made out of Mondi’s Advantage Protect White sack kraft paper, for the Australian construction market. Standout characteristics include its water repellent surface and high tensile strength in a wet environment. While a standard paper bag absorbs water, the qualities of the Rain Barrier bag, keeps water from seeping in, as it stays on the surface where it evaporates. The paper itself is rain resistant for up to six hours and can resist water ingress for up to five full days when stored in damp conditions.

German pet food maker Mera Tiernahrung GmbH has partnered with global leader in packaging and paper, Mondi, to expand its product line to include a new type of dog food with semi-moist croquettes. Mera realised that this type of pet food would require bespoke packaging to keep the chewable morsels fresh and moist for the duration of the product’s life span, while also being sustainable by design. Using Mondi's customer-centric approach EcoSolutions, which helps clients find the most effective and sustainable way to protect their products, Mondi recommended a packaging for Mera that addressed the practical aspects of food preservation without compromising on sustainability. The bag has a tight seal to ensure long-term freshness and protect the pet food inside, and is fitted with a valve to allow air to escape when palletising the bags. The reclosable zipper makes it easy for the consumer to handle, and the attractive matte-lacquer external finish makes the packaging stand out on the store shelf.

Committed to bringing innovative and sustainable solutions to the market, Klabin, Brazil’s largest producer and exporter of packaging paper and paper packaging, has developed a new version of its paperboard Klamulti, designed for beverage packaging (multipack), which now has microfibrillated pulp (MFC) in its composition. This innovation, led by the Product Development and Technology Center teams at Klabin, was produced at the MFC plant located in Telêmaco Borba, Paraná. Experiments proved that the addition of MFC in the paperboard composition significantly improves the product’s properties and performance while also reducing grammage. As such, the new solution is capable of creating lighter and more resistant packaging, enhancing the efficiency of the material. The MFC production process develops the microfibrillation of the walls of pulp fibers, enabling a wider connection area between them, thereby increasing the paper’s mechanical strength.
