Selenis has acquired the production assets of Polisan Hellas in Greece and will install them in Portugal, lifting its annual installed specialty copolyester capacity to more than 200,000 metric tonnes (MT) by 2028. The company announced the deal on October 8, 2026. Selenis describes itself as the only specialty copolyester producer manufacturing in Europe.

The capacity will sit across four countries: Portugal, Italy, Tunisia and the United States. The acquisition adds continuous polymerisation technology to a manufacturing base Selenis built on batch production.

Why does the technology split matter to buyers?

Continuous production serves high-volume markets where standardisation, consistency and cost per tonne drive procurement decisions. Batch production covers specialty and custom grades, where smaller volumes, fast changeovers and formulation depth are key.

Running both technologies across four countries lets Selenis serve the full spectrum, from high-volume shrink sleeve, film and sheet applications to specialised grades. Continuous polymerisation runs at a lower conversion cost per tonne than batch, and Selenis will direct standard grades for shrink sleeves, film and sheet onto the continuous line.

That cost base supports long-term supply agreements with customers who commit volume: multi-year, qualified and predictable on both sides.

"We believe Europe needs a strong specialty materials manufacturing base, and we are investing to build it," said Duarte Matos Gil, CEO of Selenis. "When customers qualify our materials, they make a long-term commitment. Our responsibility is to invest ahead of their needs, to put more than one plant behind every grade and to give them a cost base that lets them compete."

What does dual-site qualification change?

Supply resilience sits at the centre of the expansion. Selenis will work with customers to qualify selected grades at more than one manufacturing site, so a converter can hold the same specification from two plants. That removes dependency on a single line or region and gives converters flexibility to move volume between sites as demand and logistics shift. Qualification will follow the technical and approval requirements of each application.

Regional supply also shortens the chain. European converters are supplied from Europe and American converters from the United States, with shorter lead times and lower safety stocks than imported resin requires.

"Our ambition is to be the supplier customers choose for their next generation of products," added Matos Gil. "That takes technical depth, dependable supply from more than one plant and the capacity to grow with them."

Which markets does the investment target?

The expansion supports four priority segments:

• Shrink sleeves, film and sheet: the continuous line delivers uniform high-volume grades at a competitive cost base, backed by the packaging know-how of the wider IMG Group.
• Healthcare (Selcare®): multi-site qualification and continuity of supply are conditions of doing business in this segment.
• 3D printing (Mimesis™): PETG and PCTG resin supplied to filament producers serving industrial manufacturing, automotive, electronics, education and consumer markets, from functional prototypes to end-use parts.
• Textile-to-textile recycling (Texnascis™): Selenis works with chemical recycling partners to turn recovered monomers into new polyester, supplying the polymerisation expertise and industrial scale these technologies need to reach commercial volume.

Where does the next capacity go?

The Polisan Hellas assets will be installed in Portugal, in line with the capacity doubling Selenis has already announced and that is underway. The group is already assessing further investments.

"We are evaluating new investments in Germany in the bio-based field and in Tunisia, where we are exploring textile-to-textile opportunities through DMT technology," said Eduardo Santos, Strategy & Integration Director at IMG Group. "Each investment adds a capability to one manufacturing platform, and each is chosen for the markets where our customers see the strongest long-term growth."

For converters and brand specifiers currently qualifying specialty copolyester grades, the decision the news forces is whether to secure multi-year supply agreements now — locking dual-site qualification and regional sourcing before the 200,000-tonne platform fills with committed volume.
