At this year’s interpack trade fair, SN’s booth (A61, Hall 6) will feature two pouch packaging concepts based on Südpack’s CarbonLite film family. The first solution is a stand-up pouch with a zipper closure for grated cheese, designed as a mono-PE structure (PurePE). The second, intended for fruit purées, is a PP-based (PurePP) stand-up pouch with an integrated spout. Both materials have already been designed to meet the PPWR recyclability requirements for 2030. In terms of packaging technology, SN Maschinenbau will present the FLH 300 hygienic pouch machine and the new HSF 100 spouted pouch packaging machine, intended for small to medium output volumes and fast product changeovers.
As Felix Eberhardi, Marketing Team Leader at SN Maschinenbau, notes: “Processing recyclable packaging materials is more complex and more demanding than working with conventional materials, which makes closer collaboration with the packaging material manufacturer essential”. For this reason, SN Maschinenbau works with Südpack as well as other partners. The source information states that both companies declare a focus on responsible use of resources and food and on developing innovation. Südpack has been developing packaging films for a wide range of applications for more than six decades, while SN offers material and product trials at its Technology Center to validate new packaging materials against customer requirements and machine specifications.
CarbonLite Doypack PurePE pouch for grated cheese
The grated cheese packaging concept presented is described as a solution focused on high recyclability while maintaining process stability. Designed as a PE mono-material structure, it is intended to be returned to the appropriate recycling stream after use. The films shown at interpack have a thickness of 85 µm while providing stability comparable to conventional film laminates. The source material also highlights tailored barrier properties intended to ensure product and aroma protection. A PE-based zipper closure enables repeated opening and reclosing. It is also stated that, thanks to the film’s high thermal resistance, the zipper system can be integrated into flat and stand-up pouches with full process stability.
For the production of stand-up pouches, SN Maschinenbau will show the FLH 300 at its booth, a horizontal pouch packaging machine intended, among other applications, for products such as grated cheese. The model features a rotary system for forming, filling, and sealing flat and stand-up pouches, both conventional and recyclable, from reels (FFS). The manufacturer points to a hygienic design intended to meet strict requirements for food packaging and facilitate cleaning. Depending on product properties and pouch format, output rates of up to 270 pouches per minute are possible. Format changeovers are described as quick and largely automated, controlled via the HMI operator panel.
HSF 100 machine and CarbonLite PurePP spouted pouch for fruit purées
The second solution presented at interpack will be a spouted pouch concept intended for filling liquid products at small to medium output rates. SN indicates the HSF 100 as an intermittent-motion rotary machine that enables the production of flat or stand-up pouches with a center spout and their filling, with an output of up to 70 pouches per minute. The source material emphasizes that separating pouch production from the filling stage is intended to reduce contamination risk, especially in the spout sealing area. Filling through the spout is also stated to allow a high fill level. The concept is described as enabling production of up to 4,200 spouted pouches per hour. A compact footprint is also cited as supporting use in confined production environments, along with a simple and reliable control system from an operator perspective.
For the trade fair presentation, SN selected, in coordination with Südpack, a 121 µm PurePP spouted pouch. The film is part of the CarbonLite family and, according to the source information, can be equipped with the required oxygen and water vapor barrier properties as well as UV protection. The film, spout, and pouch packaging machine were matched within an integrated system by three manufacturers: Südpack, Menshen, and SN Maschinenbau. This is intended to ensure stable processing as well as high seal integrity and burst-pressure resistance in filled pouches, including in demanding applications such as hot filling or pasteurization.
In addition, the spout solution is stated to have been certified by the cyclos-HTP institute as 96% recyclable. According to an LCA analysis conducted by Sphera, the carbon footprint of the CarbonLite PurePP film is 57% lower overall compared with a conventional PET-aluminum film solution.
