Yogurt drinks and other protein-rich dairy products are now much more than simply food for health-conscious consumers – they have become lifestyle products in their own right and, in many cases, functional foods in liquid form. Alongside the recipe itself, packaging is also attracting increasing attention. Although bottles still dominate the market, alternative packaging concepts such as spouted pouches are gaining momentum. For this dynamic category, SÜDPACK now offers a PP-based film solution for spouted pouch production that combines high product safety, consumer convenience, and a design suitable for recycling.
CarbonLite PurePP, the material used to produce the SÜDPACK pouch, is based on polypropylene. The material’s proven sealing performance and secure spout integration deliver excellent sealing strength and lasting leak tightness, even under real-world stresses throughout the value chain, ensuring a high level of packaging reliability and product safety. In developing the packaging concept for cold-filled drinkable yogurt, SÜDPACK drew not only on its extensive extrusion expertise, but also on its considerable experience working with machine and spout manufacturers on fruit purée filling applications. This is especially evident in terms of the PP laminate’s excellent machinability on standard production machines, even at high cycle rates.
The high-performance films for spouted pouches were developed for the cold filling of drinkable yogurt and other dairy products using packaging materials that require UVC or hydrogen peroxide treatment to reduce the microbial load. The films can be tailored to provide the required barriers against oxygen and water vapor and, according to internal testing, offer the same shelf life as the PET/aluminum/PE laminates commonly used to date.
A key advantage of the new film structure is its recycling-friendly design.
