At Interpack, Hesser Packaging GmbH and Südpack are presenting a packaging concept for whole coffee beans and ground coffee in a 1 kg format. The stable stand-up pouches are made from films from the CarbonLite family based on polypropylene (PP), which is intended to enable recycling. According to the manufacturers, the solution provides a high barrier to oxygen and water vapour, supporting aroma and freshness protection, as well as protection against UV radiation. Hesser’s booth is located in the Packaging Valley area, Hall 16, Booth 16D72-10.
The release also highlights an organisational change involving Hesser Packaging GmbH. As of 1 February 2026, the company operates as an independent Syntegon subsidiary responsible for the packaging machine business and for continuing activities in packaging solutions. Hesser focuses on new machines, service and valves for primary packaging of dry foods such as coffee, flour and sugar.
CarbonLite films and design-for-recycling assumptions
According to Südpack, flow pack films in the CarbonLite family are intended to combine material efficiency, recyclability and performance. These are PP-based mono-materials that are described as lightweight and more than 90% recyclable, in line with current PPWR design principles and based on internal calculations. The manufacturer states that compared with conventional laminates, the solution is intended to significantly reduce the carbon footprint. The material cites PET/Alu/PE laminates as an example of conventional structures. It is also emphasised that, thanks to cooperation with machine manufacturers, the films can be processed on existing equipment on an industrial scale.
Stand-up pouches for coffee: barrier performance, UV and sealing with a valve
At the trade fair, Hesser is set to present stand-up pouches made from Südpack high-performance films for coffee packaging. According to the companies, the oxygen and water vapour barriers have been optimised for the packaged product to ensure long shelf life, freshness and aroma protection. Optional white pigmentation or metallisation is provided for protection against UV radiation.
The release points to the importance of sealing parameters for product safety and packaging reliability, including reliable integration of aroma protection valves into the sealing process. Südpack also lists available packaging printing technologies: rotogravure, flexography, digital printing and 7C printing, with the option to tailor them to the product, artwork and customer requirements.
PMX 4001: vertical flow pack machine for PP pouches
Hesser is announcing the PMX 4001 as a machine intended for producing PP stand-up pouches. It is a compact, robust vertical flow pack machine designed for the requirements of coffee packaging. It can be used as a standalone machine or integrated into a turnkey line.
According to the figures provided in the material, the PMX 4001 achieves an output of up to 65 pouches per minute in 24/7 operation (based on 500 g packs of whole coffee beans). The machine is intended to produce a wide range of pouch formats and sealing options while maintaining first-class seam quality. The listed capabilities include longer evacuation times for achieving a deep vacuum to protect the product’s aroma and high weight accuracy during high-speed filling. The manufacturer also mentions IO-Link and Synexio integration to provide real-time data for process optimisation and predictive maintenance. The open design provides access from all four sides, which is intended to simplify cleaning and minimise changeover times.
