Cirkla integrates resealable film into fiber trays without replacing existing packaging lines

For years, the transition from rigid plastic to molded fiber in the refrigerated aisles has hit a functional wall. Brands wanted the sustainability metrics, but consumers demanded the convenience of peel-and-reseal functionality. Until now, bonding a resealable lidding film to a fiber substrate without destroying the tray's liner upon opening was a technical hurdle that kept rigid plastics dominant in fresh protein and produce applications. That barrier has just been dismantled.

In a significant move for the US packaging sector, Cirkla Inc., Belmark Inc., and Ossid have jointly launched what they validate as the first commercial-scale resealable fiber tray system. This is not merely another "green" tray entering the market; it is a targeted engineering solution designed to solve three historical bottlenecks: resealability, shelf-life parity with plastic, and compatibility with installed machinery.

The mechanics of the integration

The system relies on a tripartite approach. Cirkla provides the high-barrier molded fiber tray, which the company claims reduces plastic by up to 90% by weight compared to conventional rigid alternatives. Belmark brings the critical peel/reseal lidding film technology, engineered specifically to adhere to Cirkla's proprietary fiber liner without compromising the structural integrity of the package during multiple uses.

However, the most crucial element for market adoption is the machinery integration. Ossid, a ProMach brand, facilitates the automated sealing through its ReeMaster NextGen Automatic Tray Sealer. The equipment supports top-seal, Modified Atmosphere Packaging (MAP), and Vacuum Skin Packaging (VSP). By ensuring that these fiber trays run seamlessly on existing major US tray sealers, the consortium eliminates the need for massive capital expenditure or complete line overhauls—a primary objection from protein processors.

Scaling up domestic production

This technological breakthrough coincides with Cirkla's aggressive expansion in the US market. The company is currently preparing its first American manufacturing facility in Gainesville, Georgia. Scheduled to commence operations in Q1 2027, the plant will provide the necessary domestic supply chain infrastructure to support large-scale rollouts for national grocery retailers and meat brands.

By addressing the functional deficits of fiber packaging while respecting the operational realities of food processors, this collaboration sets a new baseline for the industry. The true test will now be the speed of adoption among top-tier US protein packers who have been waiting for a plug-and-play fiber solution.

This tripartite development proves that the future of packaging innovation lies in cross-disciplinary partnerships rather than isolated R&D silos. Will the ability to run resealable fiber on existing MAP lines finally trigger the mass exodus from rigid plastics in the US meat sector?
