Saica Just Added 2,500 Employees and 1.2 Billion m² of Corrugated Capacity — What Changes for Everyone Else?

The deal is no longer pending.

On August 24 — two days ago — Saica Group and THIMM Group confirmed that the acquisition has been successfully closed. The transaction announced in May and cleared by the European Commission in July is now legally effective: nearly 2,500 THIMM employees and the group’s operations in Germany, Poland, the Czech Republic and Romania are now part of Saica, while all plants will continue operating.

Saica Group has completed its acquisition of THIMM, bringing the corrugated packaging operations in Germany, Poland, the Czech Republic and Romania into the Saica network.

This is the new part of the story. Saica has not announced another plan. It now controls an operating corrugated network with around 1.2 billion m² of annual packaging capacity and a business that generated approximately €541 million in 2025, according to current THIMM company information.

For plant directors, three questions now matter more than the closing itself: where the paper will come from, whether service and lead times improve, and whether Saica can turn THIMM’s higher-value converting capabilities into a stronger multi-country offer.

Integration of ERP, MES, planning, quality and customer data
Retention of key managers, technical specialists and major accounts

The money is undisclosed, but the industrial scale is not

The purchase price remains confidential, so any attempt to value the deal from public information would be speculation.

The industrial scale is visible. Saica is taking control of nine corrugated board plants in Alzey, Wolnzach, Eberswalde, Castrop-Rauxel and Northeim in Germany; Tychy and Skarbimierz in Poland; Všetaty in the Czech Republic; and Sibiu in Romania, plus the preprint operation in Ilsenburg, Germany.

This is not greenfield capacity waiting to be built. The plants, people, customer relationships and production are already there. The challenge is no longer construction. It is integration.

The paper-flow question may be bigger than the headline

Saica is not only a box producer. Saica Paper manufactures recycled papers for corrugated board, giving the group a vertically integrated position across recovered fibre, paper and packaging.

Poland is where this becomes especially interesting. Saica lists 280,000 tonnes of annual paper capacity at Myszków and 140,000 tonnes at Grudziądz — 420,000 tonnes combined. THIMM now adds converting operations in Tychy and Skarbimierz.

There is no public evidence yet showing how Saica will allocate paper to the acquired plants, so it would be wrong to call them guaranteed captive outlets. But the strategic option is obvious: Saica now has a larger internal converting network close to its own Polish paper production.

For paper suppliers and competing converters, this may become one of the most important post-deal indicators. The integration story could be measured not only in square metres of boxes, but in how fibre moves through the combined system.

The completed THIMM acquisition adds around 1.2 billion m² of annual corrugated packaging capacity, nearly 2,500 employees and a business generating approximately €541 million in 2025 revenue.

Saica bought more than standard box capacity

THIMM’s value is not limited to conventional corrugated boxes. Its portfolio includes transport, shipping and sales packaging, promotional displays and preprint for industrial processing.

THIMM also has capabilities in digital printing, digital laser cutting, shelf-ready packaging and e-commerce solutions. The Ilsenburg preprint operation adds know-how that sits above commodity RSC production.

That matters because margin in corrugated packaging is not created by volume alone. High-quality print, retail-ready formats, short runs, e-commerce optimisation and differentiated display solutions can carry more value than standard brown-box production.

The real question is whether Saica can combine its scale and paper position with THIMM’s higher-value converting and print capabilities.

Why this deal matters now

The Saica–THIMM closing lands in the middle of a broader restructuring of European paper and packaging.

Smurfit Kappa and WestRock completed their combination in July 2024. International Paper completed its acquisition of DS Smith on January 31, 2025. Saica has now closed THIMM and strengthened its position in Central and Eastern Europe.

Mathias Schliep, Chairman of the Board of Directors at THIMM Group, put the consolidation pressure plainly: “only a small number of large players will be able to gain market share in the future.”

That sentence explains much of the logic behind the deal. Scale now means more than production volume: it means capital for technology, wider geographic coverage, paper access, data systems, sustainability capabilities and the ability to serve multinational customers across several countries.

The European Commission cleared the transaction under merger rules and said it did not raise competition concerns. So “oligopoly” would be too strong. But the direction is clear: larger integrated groups are becoming more influential across paper, corrugated packaging, recycling and multi-country customer accounts.

Editorial illustration: the Saica–THIMM deal creates a larger corrugated packaging network — with paper flows, service, technology and integration now becoming the key questions to watch.

PPWR raises the integration stakes

The timing is also unusually relevant. The EU Packaging and Packaging Waste Regulation began applying on August 12, 2026 — less than two weeks before Saica and THIMM confirmed the closing.

PPWR makes packaging compliance increasingly dependent on consistent design rules, material information, supplier evidence and technical documentation across sites. For a group operating a larger network, that is not only a legal challenge; it is a systems challenge.

Scale can help if design expertise, testing, data and compliance processes are shared. But fragmented ERP, quality systems or product data can turn a larger footprint into a larger coordination problem.

For Saica, operational integration and regulatory integration now arrive at the same time.

The biggest integration risk is not the machinery

Saica and THIMM have worked together since the late 1990s, including a strategic sales alliance and a joint venture in Poland. That history may reduce some of the cultural friction that often follows a major acquisition.

But the THIMM family is fully exiting the company. The difficult questions now involve people, customers and systems: retention of key managers, integration of procurement, harmonisation of ERP and production planning, customer ownership, service standards, investment priorities and eventually branding.

Saica says all plants will remain operational. That provides continuity. It does not remove post-merger integration risk.

The strongest acquisitions are not the ones that simply keep production running. They are the ones that improve utilisation, shorten response times, remove duplicated processes and make customers notice a better service level.

What changes for corrugated producers?

For multinational customers, the enlarged Saica network could provide broader geographic coverage, more backup production options and a stronger ability to serve several countries through one supplier relationship.

For independent and regional converters, competing only on price becomes even less attractive. Speed, local service, specialist converting, short-run flexibility, technical support and close customer relationships become more important against a larger integrated network.

The deal may also change internal paper flows and purchasing patterns, but there is not enough public evidence to make a credible forecast for European containerboard prices from this transaction alone.

That is why the next 12 months matter more than the undisclosed purchase price.

The 12-month scoreboard

Paper flows: does more Saica Paper move into former THIMM plants, particularly in Poland?
Plant utilisation: are volumes redistributed between Tychy, Skarbimierz and other sites?
IT integration: how quickly are ERP, MES, planning, quality and customer-data systems harmonised?
Product mix: does Saica invest further in preprint, digital print, displays and e-commerce packaging?
People: are key THIMM managers, technical specialists and major customer relationships retained?
Service: do lead times, delivery reliability and technical support improve?
Customers: does the enlarged network win more multi-country contracts?

The acquisition story is over. The integration story starts now.

1.2 billion m² of corrugated packaging capacity has changed hands. The next question is how much more value Saica can create from every square metre.
