Effective immediately, high-performance tubular pouch films from the premium Pure-Line range of Sudpack – a leading manufacturer of high-performance films and packaging solutions for the food, non-food, and medical goods industries – are being consolidated into a dedicated product family and marketed under the CarbonLite brand.
Based on PP and PE mono-materials, these films can be processed on both horizontal and vertical flow pack machines into flowpacks, doypacks (with or without spouts), and block-bottom pouches.
Most importantly, their recyclability and optimized material efficiency result in a significantly smaller carbon footprint compared to conventional multi-material laminates or heavier tray packaging – offering clear economic advantages, including lower disposal costs.
Sudpack’s next-generation top webs are ideal for MAP applications and have been engineered for greater sustainability. For example, a CarbonLite PurePP flowpack uses up to 60% less material than a conventional tray, while the packaging concept also achieves recyclability rates of up to 92% – verifiable by external institutes. For horizontal PE-based flow pack applications, Sudpack has achieved a further reduction in film thickness while maintaining barrier properties and cutting material usage by an additional 10%. In addition, by adopting Sudpack’s sustainable packaging concepts, manufacturers and packagers can typically achieve a shorter time-to-market – supported by Sudpack’s co-extrusion expertise, comprehensive service, and in-house application center.
Typical application scenarios
The films in the CarbonLite series are suitable, for example, for use as lightweight PE flowpacks for cuts of cheese, baguettes, mozzarella, and coffee; as PP flowpacks for ground meat and convenience products; and as stand-up PE doypacks for grated cheese and salami sticks, as well as PP doypacks for confectionery, dried fruit, nuts, and other snacks. For coffee applications, the films can also be processed into stable PP or PE block-bottom pouches, and into convenient PP spouted pouches for fruit purées.
Despite their wide range of applications, all films share one essential feature: barrier properties precisely tailored to each product – such as protection against oxygen and water vapor – that ensure a long shelf life for a wide variety of foods. For enhanced product visibility, a high-performance anti-fog feature can be added if required.
At the same time, the films can be processed efficiently on standard packaging machines, even at high cycle rates. A key factor in ensuring both product and packaging reliability is the films’ consistently strong sealing performance, a result of their high thermal resistance – even when incorporating zippers, spouts, or valves made from the same mono-material.
Further ecological advantages
As a leader in sustainability and the circular economy in the plastics and packaging industry, Sudpack considers more than just the carbon footprint and end-of-life of its films. With its groundbreaking SPQ printing technology, the company also makes package printing more sustainable – significantly reducing ink and solvent consumption while enhancing color brilliance.
The film manufacturer, which has committed to the SBTi and was one of only a few companies to achieve Platinum status in the EcoVadis ranking in 2025, also offers its advanced LCA service – a powerful tool for assessing the eco-balance of various packaging concepts. This service evaluates not only Sudpack’s own product developments but also customer solutions.
Sudpack is a leading manufacturer of high-performance films and packaging solutions for the food, non-food, and medical goods industries, as well as customer-specific compounds for technically demanding applications.
