German industrial packaging specialist Ringmetall SE has agreed to acquire 100 percent of Rapak, LLC, a US manufacturer of bag-in-box packaging, dispensing components and liquid filling equipment, from American packaging group TriMas Corporation. The acquisition represents a significant step in Ringmetall's expansion into the global beverage packaging industry, particularly in North America.
The transaction, announced on October 29, is scheduled to close on November 2, 2026. The purchase price has not been disclosed. Rapak, headquartered in Woodridge, Illinois, operates facilities in Woodridge and Indianapolis, Indiana. With approximately 50 employees, the business generates annual revenues of around USD 20 million. Ringmetall intends to finance the acquisition through existing funds and available credit facilities. According to the German company, the deal will make it the world's fourth-largest manufacturer of bag-in-box packaging systems.
Despite its relatively modest size, Rapak is an established specialist in an important segment of the global beverage packaging market. Its products are used to package and dispense wine, fruit juices, drinking water, soft drink concentrates, dairy beverages and other liquid products. Bag-in-box systems are particularly important in the foodservice industry, where restaurants, fast-food chains and hospitality businesses use large flexible bags containing concentrated soft drink syrups connected directly to dispensing machines.
Unlike manufacturers supplying only flexible packaging materials, Rapak offers integrated systems comprising specialized barrier films, bags, taps, connectors and filling machinery. This combination is strategically important because beverage producers require compatible packaging components and filling technology to ensure hygienic processing, product stability and efficient dispensing. For customers investing in new production lines or converting from rigid containers to flexible packaging, Rapak can provide a complete technical solution.
The company's product portfolio includes the Mustang dispensing system for wine, designed to minimize oxygen exposure and help preserve product quality after opening. Rapak also supplies DuraBev bags for post-mix soft drink syrups, featuring puncture-resistant films and efficient product evacuation. Its Autokap filling machines include semi-automatic and fully automated systems capable of handling bags ranging from 1.5 to 20 liters. Specialized IntaSept technology additionally enables aseptic filling of sensitive liquid products.
These technologies have particular relevance for wineries and producers of juices and other beverages sensitive to oxygen or microbiological contamination. High-barrier films and suitable dispensing systems can reduce oxidation, extend shelf life after opening and minimize product losses. Bag-in-box packaging also offers logistical advantages through lower packaging weight and reduced storage requirements. Depending on the application, these benefits can reduce transport costs and greenhouse gas emissions compared with conventional rigid packaging, although the environmental performance depends on the materials used and their disposal or recycling.
Rapak also has a history of developing packaging solutions specifically for the brewing industry. As early as 2006, the company introduced a bag-in-box system for draft beer in cooperation with Bavarian brewery Ankerbräu in Nördlingen, Germany. The system used flexible beer bags instead of conventional steel kegs, with carbonation restored through a specialized dispensing unit. In 2018, Rapak was still promoting bag-in-box beer packaging as an alternative to returnable kegs, emphasizing lower transport costs, the elimination of keg returns and improved storage efficiency. However, this application has remained a specialized segment rather than becoming a mainstream replacement for traditional beer kegs.
Rapak's corporate history reflects several decades of consolidation in the international packaging industry. The business originally operated as part of the US packaging company Packaging Systems LLC, which combined bag-in-box packaging expertise with filling machinery and integrated packaging line technology. British packaging group DS Smith acquired Packaging Systems and its Rapak business in 2000, subsequently developing Rapak into an internationally recognized brand within its plastics division.
A major ownership change occurred in 2020, when US-based Liqui-Box, then controlled by private equity investor Olympus Partners, acquired DS Smith's plastics division. The transaction attracted scrutiny from the US Department of Justice because of overlapping activities in the American bag-in-box packaging market. To satisfy competition requirements, Liqui-Box agreed to divest selected Rapak operations and product lines.
On April 17, 2020, TriMas acquired these operations, related assets and global rights to the Rapak brand for approximately USD 11.4 million, according to the company's regulatory filings. The acquired business had generated approximately USD 30 million in annual revenues in 2019, although the scope of the assets acquired at that time is not necessarily directly comparable with the business being sold in 2026. TriMas integrated Rapak into its packaging division alongside its other dispensing and closure businesses.
The latest sale therefore represents another change in Rapak's ownership, this time from US-listed TriMas to Germany's publicly traded Ringmetall. TriMas confirmed the disposal in its third-quarter 2026 results, describing the transaction as part of its strategy to streamline its portfolio and concentrate on selected core businesses.
For Ringmetall, the acquisition fits into an aggressive international expansion strategy. Traditionally known for industrial drum closure systems and protective liners, the Munich-based group has increasingly diversified into flexible packaging for food and beverages. Its existing businesses include Peak Packaging Poland, which produces bag-in-box systems and liners for applications including beer, wine, juices and dairy products.
In August 2026, Ringmetall acquired a 75.1 percent interest in the South African company Tesseraux SA, which incorporates the operating business of bag-in-box producer Vinbag. The South African operation supplies packaging in sizes ranging from 1.5 to 25 liters, particularly for wine, fruit juice and foodservice applications. Other acquisitions during 2026 included Turkish liner manufacturer Makplast and the thermoforming business of New England Plastics in the United States.
Rapak is Ringmetall's fourth acquisition in 2026 and adds a strategically important component to this expanding international network. While its existing subsidiaries primarily strengthen the group's manufacturing capacity for flexible packaging materials, Rapak also contributes established filling technologies, dispensing expertise and customer relationships in the North American beverage industry.
Christoph Petri, co-CEO of Ringmetall, emphasized that the acquisition provides access to the growing North American bag-in-box market while complementing the group's existing liner portfolio in the United States. Management expects additional earnings potential through operational integration and synergies.
Ringmetall itself has undergone a substantial transformation since its establishment in 1997 as H.P.I. Holding AG, initially a diversified investment company. After going public on the Frankfurt Stock Exchange in 2007, the Munich-based group increasingly concentrated on industrial packaging, adopting the Ringmetall name in 2015 and converting into a European company (SE) in 2021. Today, its core activities comprise industrial drum closure systems and flexible liners for industrial and beverage applications. Ringmetall claims a global market share exceeding 50 percent in drum clamping rings. In 2025, the group generated revenues of EUR 187.7 million and employed approximately 1,000 people. Although publicly listed, the company has a concentrated ownership structure: according to its latest published major voting-rights notification from May 2023, a shareholder agreement involving its two executives, Christoph Petri and Konstantin Winterstein, controlled 59 percent of voting rights, with the remaining shares held by other investors. This gives management a controlling voting bloc and considerable influence over the company's acquisition-driven expansion strategy. Since divesting its industrial handling operations in 2023, Ringmetall has focused entirely on industrial packaging, increasingly expanding into beverage applications through acquisitions such as Dutch beer-tank specialist FIB Beer Systems in 2024.
For beverage producers, the transaction could create a stronger international supplier capable of delivering flexible packaging materials, specialized dispensing components and filling equipment across several important markets. In particular, the combination of Rapak's technological expertise with Ringmetall's expanding manufacturing network could strengthen competition in packaging solutions for wine, fruit juices, soft drinks and other liquid beverages. The commercial impact will ultimately depend on how successfully Ringmetall integrates Rapak's operations and technology into its global packaging business.
