Ringmetall Completes Rapak Acquisition From TriMas

Ringmetall has acquired Rapak from TriMas, Woodward Park Partners announced on November 2, 2026, completing the sale of a US producer of flexible bag-in-box packaging and associated filling systems. The parties agreed not to disclose the purchase price.

Ringmetall announced on October 29, 2026 that it had agreed to acquire 100% of the shares in Rapak, with closing scheduled for November 2. The buyer planned to finance the acquisition with its own funds and available agreed credit lines. TriMas (TRS ) reported in its third-quarter results that it signed the Rapak sale agreement in October 2026 and expected the transaction to close in November 2026. Woodward Park Partners advised TriMas on the sale.

Rapak is headquartered in Woodridge, Illinois, and operates from two sites there and in Indianapolis, Indiana. It produces flexible bag-in-box bags and filling systems for liquid food, beverages and industrial applications. Ringmetall reported annual revenue of around US$20 million at Rapak and a workforce of approximately 50.

TriMas acquired Rapak in 2020, and the business subsequently operated within TriMas Packaging. TriMas characterized the divestment as further advancing its portfolio-optimization strategy.

Munich-based Ringmetall supplies industrial packaging, including closure systems and inner liners for industrial drums used in the chemical, pharmaceutical and food-processing industries, as well as packaging solutions for the beverage industry. Its production and sales network extends across Europe and to China, the United States and South Africa.

The acquisition takes Ringmetall into the North American bag-in-box market and strengthens its Liner business unit. Rapak adds bag-in-box systems and associated filling technology to the group’s existing North American liner portfolio. By Ringmetall’s own estimate, the transaction makes it the fourth-largest manufacturer of bag-in-box systems worldwide.

Ringmetall’s October 29 plan called for Rapak to be integrated into the group shortly after closing. The buyer also identified potential synergies to be realized during integration and additional earnings potential for Rapak resulting from those synergies.

TriMas President and CEO Thomas Snyder said, “The transaction represents another important step in streamlining our portfolio and increasing our focus on businesses and end markets where we believe we have the greatest opportunity to drive profitable growth and attractive returns.” He also described Ringmetall as a strong strategic owner positioned to support Rapak’s continued growth and success.

Ringmetall Co-CEO Christoph Petri said Rapak was the group’s fourth acquisition of 2026, following Makplast, New England Plastics’ thermoforming division and Vinbag, and presented the deal as part of a buy-and-build strategy supported by rapid integration and the use of existing synergies.

The completed transaction moves Rapak out of TriMas Packaging and into Ringmetall, with integration into the buyer’s group the next step disclosed in the October 29 plan.
