- Syntegon develops new paper-based packaging concept for “PACK4SENSE” project
- Optimized recyclability thanks to easier separation of all packaging components
Waiblingen, Germany – As part of an EIT-funded project, Syntegon has developed paper-based trays and cups for sensitive food products. Together with partners from industry and research, namely Fraunhofer Institute for Process Engineering and Packaging in Dresden, Colruyt Group, Strauss Group and the University of Reading, Syntegon is implementing the EIT project “PACK4SENSE” (Paper packaging for SENSitive foods) to develop a sustainable packaging concept. EIT Food, the world’s largest and most dynamic innovation community, is supported by the European Institute of Innovation and Technology (EIT), a body of the European Union.
Optimal recyclability thanks to paper And mono-material
The aim of the project is to pack even sensitive products with high barrier properties in more sustainable materials. Syntegon uses a special paper, which is particularly stretchable and tearproof thanks to long cellulose fibers, thus enabling the production of sealed trays and cups with a depth of up to 30 millimeters.
A recycable barrier layer made of 95 percent mono-materials provides optimal product protection. The paper and the barrier layer, as well as the cover film can be easily separated, ensuring full utilization of its recyclability.
The new paper-based trays allow to pack even sensitive products with high barrier properties in more sustainable materials.

The sealed trays and cups with a depth of up to 30 millimeters are fully recyclable: The paper and the barrier layer, made from 95 percent mono-material, as well as the cover film can be easily separated for easy disposal in different waste streams.

Using a particularly stretchable paper that can withstand wrinkling during the forming process on the Syntegon TPU machine, allows to form individual shapes for optimal product presentation.

This sustainability advantage, however, also poses challenges for packaging manufacturers. On the one hand, consumers should be able to separate all components for waste sorting. On the other hand, paper and film must not be detached from each other unintenionally. To prevent this from happening, the TPU paper forming, filling and sealing machine from Syntegon forms paper and barrier layer in a common process by thermoforming and pressing. “With the paper-based trays from the “PACK4SENSE” project, we have further developed our previous paper packaging solutions like the shaped paper pods – structured paper trays for the packaging of cosmetics and confectionery,” explains Matthias Klauser, project manager and sustainability expert at Syntegon.
TPU brings paper and barrier layer together
The TPU has already been honored with the German Packaging Award in 2020 and is Syntegon’s flagship machine for paper forming. For the PACK4SENSE trays and cups, the paper runs directly from the roll into the feeder – the barrier layer required for sealing is applied and joined to the paper without any further conversion step. Alternatively, manufacturers can use a converter to connect paper and protective layer of mono-material without heating. A forming station presses the materials into shape before the trays are filled and sealed. In addition to using a particularly stretchable paper that can withstand wrinkling during the forming process, it is important to preserve the separability of the materials: a specially adapted geometry of the forming tools reduces the tension on the materials during the manufacturing process.
Syntegon is continously working on further developing its paper-forming technology. EIT Food enables the company to work closely with important partners and to test products together with consumers and food manufacterers. This cooperation makes it possible to develop prototypes and solutions that meet product requirements and optimize the sustainability of packaging step by step.
