# RDM Acquisition: Is Europe's Recycled Paperboard Market Entering a Three Kingdoms Era?

*File Preparation · 6 min read · 2026-09-28*

> The European Commission has received notification of M&G and Arini Capital's proposed acquisition of RDM, and control of Europe's recycled paperboard sector may be reshuffled. Designers can start with paperboard, proofing, and alternative specifications, building supply risk into the final-artwork workflow

**Quick answer:** M&G and Arini Capital plan to jointly control RDM through a shareholding arrangement. The deal is still subject to EU merger review. Mai Strategy's Three Print-Ready Gates require design teams to lock in the paperboard, color, and alternative specifications first

## Why should a proposed acquisition matter to designers?

Because the European Commission, the body responsible for implementing EU policy and handling competition reviews, received the acquisition notification on September 1, 2026. RDM's control structure may change, giving design teams reason to check paperboard risks early.

Recycled paperboard is board made mainly from recovered fibers and used for folding cartons and corrugated packaging. Fiber sources, strength, shade, and surface smoothness all affect design and printing conditions.

ThePackagingPortal article published on September 24, 2026, [M&G and Arini Capital Propose to Acquire RDM](https://www.thepackagingportal.com/industry-news/mg-and-arini-capital-eye-up-take-over-of-rdm/), says M&G Investment Management Ltd and Arini Capital Management Ltd plan to acquire Reno de Medici S.p.A. (RDM). The two parties plan to obtain joint control of RDM by purchasing shares. RDM is currently controlled by Apollo Management, L.P.

At this stage, the phrase "Three Kingdoms era" can describe only a reshuffling of the control positions held by M&G, Arini, and Apollo. It cannot yet be treated as fact that the three companies have divided up the European market.

## What exactly is the "new Three Kingdoms era" reshuffling?

Control rights would be reshuffled first. Paper types, capacity, distribution channels, and prices might be affected later. For now, the only confirmed facts are the joint acquisition proposal and the EU's preliminary review.

Joint control means two buyers jointly gain influence over major company decisions through their shareholdings. The direction of decisions on raw-material procurement, equipment investment, customer mix, and regional sales could change, but that does not mean every item will shift immediately after the announcement.

If the paperboard grade, the grade and specifications of the board, usually tied to basis weight, thickness, stiffness, and surface conditions, changes with the supply source, the first question designers should ask is not "Is there paper?" but whether the same grade can be obtained consistently and who approves the alternative grade.

The EU Merger Regulation is the framework the EU uses to determine whether a corporate transaction requires competition review. The source says the European Commission preliminarily considers this case potentially within the scope of the regulation, but no final determination has been made.

It is too early to treat higher paper prices or shortages as established facts. Start by listing packaging projects that depend on a single grade, and procurement and final-artwork teams will have something they can act on immediately.

## What kind of paperboard risk will Taiwanese designers encounter first?

The first thing that usually surfaces is that once the same file is printed on a different stock, the color, detail, and converting performance are no longer exactly the same.

When paperboard whiteness, ink absorption, thickness, or stiffness changes, the same CMYK, the cyan, magenta, yellow, and black print color model, values may produce different results. Solid dark fills, fine type, and graphics around die-cut and crease lines are often the first places where the difference shows.

For example, a brand's folding carton may originally use a warm-toned recycled paperboard. Move the key visual to a whiter or rougher grade, and its visual warmth, fine-type edges, and crease-line positions all need another look. In paperboard carton projects, what I fear most is seeing the file stay the same while the finished product changes first.

Prepress, including file checking, color management, and proofing, cannot stop at checking bleed and resolution. The actual paperboard must also be reflected in the color settings. ISO 12647-2, the international standard for process control in offset printing that provides a common reference for printing conditions, still will not tell you which color profile, a settings file describing the paperboard and printing conditions, to use for a particular recycled paperboard.

Proofing, the sample used to confirm color and finished-product results before mass production, needs to be confirmed together with the paper sample, printing method, and surface finishing. Otherwise, no matter how accurate the blue on screen is, changing the paperboard may still send you back to square one.

## How should designers use "Mai Strategy's Three Print-Ready Gates" now?

Confirm the paperboard at the quotation stage and before final artwork, and keep traceable records through the three checkpoints: paperboard, color, and alternatives.

・1. Paperboard checkpoint: Record the current grade, paper color, surface, thickness (caliper), stiffness, and the supplier's response. Use the same name in the file notes and purchase order.

・2. Color checkpoint: Mark brand colors, solid dark fills, fine type, and die-cut and crease lines as mandatory review areas. Keep the paper sample and proofing conditions. Do not provide only CMYK values.

・3. Alternative checkpoint: List acceptable alternative grades and specify which layouts need to be reproofed. A material change must be approved by the design and brand teams before mass production.

・4. Pre-delivery self-check: Confirm that bleed, resolution, color settings, paperboard name, and version number match. If the paper sample differs, ask what changed before proceeding.

For mid- to high-end custom folding-carton or commercial-printing projects, you can send the paper sample, files, and proofing conditions to MINDS for confirmation, so paperboard discussions are settled before mass production.

## The acquisition is not settled yet. What should the Taiwanese supply chain be watching?

First watch for the European Commission's final decision and whether control of RDM actually changes hands. Then watch for suppliers to update their grades, lead times, and alternative-material policies.

The public material currently confirms only that the notification was received on September 1, the news was published on September 24, and the case may preliminarily fall under the Merger Regulation. A final decision is still pending. Those facts are enough to start an inventory, but not enough to prove that paper prices, supply volumes, or Taiwanese quotes have already changed.

Brand clients can ask printers to identify the current grade, alternative grade, and proofing items that must be redone after a material change in the quotation. Printers, in turn, should keep the supplier's response, paper sample, and approved version on the same job ticket.

The shifting positions of M&G, Arini, and Apollo are a reminder to procurement teams: paperboard decisions now touch final-artwork design directly. By the time you ask, "Where is the paper?" at mass production, you are usually already one round late.

## Key takeaways

・A proposed acquisition is not the same as a completed deal, but it is enough for design teams to start auditing recycled-paperboard sources.

・"Three Kingdoms" currently points to a reshuffling of the control relationship among M&G, Arini, and Apollo. It does not mean the three have already divided up the market.

・Once the recycled paperboard changes, CMYK, fine type, crease lines, and converting results all need to be checked against the actual paper sample.

・Before sending to print, put the current and alternative grades in writing. Procurement then will not have to change the specifications at the last minute before mass production.

## Further thoughts

Manufacturers can put the grade, supplier response, paper sample, proofing details, and material-change approval into one job ticket. Before using AI to generate packaging visuals or create layout variants, design teams should lock in the paper color and surface conditions. Otherwise, the visuals may come together quickly, but production still has to recalculate the color. SaaS, cloud software provided on a subscription basis, teams can make the paperboard fields, version lock, and material-change approval mandatory. The next step is practical: identify the projects on hand that depend on a single recycled-paperboard grade, and add the alternative specifications and reproofing conditions to each one.

## FAQ

### Has M&G and Arini Capital's acquisition of RDM been completed?

Not yet. On September 1, 2026, the European Commission received the proposal. Public material released on September 24 only said that the case may preliminarily fall under the Merger Regulation. A final decision is still pending.

### Will the RDM acquisition immediately cause recycled paperboard prices to rise?

That cannot be concluded yet. The material confirms a control transaction and a preliminary review, but it does not establish that paper prices, supply volumes, or Taiwanese quotes have already changed.

### How can designers reduce the risk of a recycled-paperboard material change?

Before final artwork, specify the current grade, paper color, surface, and proofing conditions, and list acceptable alternative grades. When materials change, reconfirm color, fine type, crease lines, and converting results.

### Why would the RDM acquisition affect Taiwanese designers?

If control of RDM changes, supplier contacts, paperboard specifications, and alternative-material approval processes may all need to be coordinated again. Design teams should put these conditions in the files and job tickets first.
