Südpack has consolidated its recyclable Pure-Line pouch films under the CarbonLite brand and updated the range with a focus on sustainability and performance. The portfolio comprises mono-material structures based on PP and PE as alternatives to non-recyclable composites and aluminum-based films. The films are designed for common pouch formats, including lightweight flowpacks, doypacks and block-bottom pouches. Target applications include nuts, bakery products, dried fruit and other snacks. According to the company, the materials are intended to conserve resources and reduce environmental impact while maintaining product protection and shelf life. Performance is attributed to barrier properties against oxygen and water vapor as well as secure sealing, which support flavor retention and texture over time.
Material structures and product protection
The films are specified to meet typical snack packaging requirements through tailored barrier configurations for oxygen and water vapor. For light-sensitive contents such as dried fruit, high-opacity white pigmentation is used to shield against UV exposure and discoloration. Drawing on co-extrusion expertise and project experience, Südpack reports that the mono-material films run on standard packaging equipment and enable a range of pouch formats with efficiency, process reliability and packaging security comparable to conventional multilayer structures. The films’ thermal resistance supports secure sealing, including for reclose features. To maintain mono-material end-of-life concepts, zippers are available in both PP and PE versions.
Recyclability, printing and services
CarbonLite is positioned as aluminum-free and highly recyclable, and it is designed with the requirements of the upcoming PPWR in mind. A Pure PP flowpack from the range achieves a 92% recycling rate as certified by cyclos-HTP. In printing, the company’s SPQ technology is intended to reduce ink and solvent consumption while enhancing color consistency and brilliance. Südpack also offers an LCA service that assesses the environmental profile of packaging concepts across the value chain, including multiple end-of-life options, to support fact-based decision-making. The company states that switching to these solutions can shorten time-to-market, supported by in-house services and an application center.
