Südpack offers a large range of sustainable flowpacks for convenience foods

The flowpack has become the go-to packaging format for these products. Why? This transparent, convenient pouch requires minimal material, offers excellent product protection, and is both widely accepted and favored by consumers. In a continued effort to promote sustainability, Südpack has established an extensive product range under the Pure Line brand. These monofilms are based on PP or, optionally, PE. They are recyclable and provide a fully functional and high-performing alternative to conventional multi-material laminates.

According to a detailed life cycle assessment based on internal calculations, Südpack’s Pure PP flowpacks achieve a recyclability rate of over 90%. This already lightweight packaging concept is 7% lighter than pouches made from conventional materials – a difference that positively affects emissions and disposal costs across the entire supply chain. In total, CO₂ savings compared to a conventional PA/PE laminate are around 27%. The differences are even more significant when compared to considerably heavier trays, which are still commonly used for packaging fresh pasta.

Integrated barrier properties – especially a high oxygen barrier – help maintain freshness and extend the product’s shelf life. Despite their low material thickness, these PP- and PE-based packages offer the stability needed to ensure maximum product protection throughout the entire logistics chain – right up to the end consumer. Their high transparency also enhances shelf appeal at the point of sale.

Although PP films are typically more challenging to process than conventional film laminates, Südpack’s advanced coextrusion expertise enables these sustainable materials to run just as efficiently on existing packaging machines. “Thanks to the wide processing window, throughput remains virtually unchanged,” the film manufacturer emphasizes. PP monofilms are also ideally suited for thermal treatment and pasteurization – both of which play a critical role in ensuring a long shelf life.
