Graphic Packaging International (GPI) has announced the launch of a new line of PaperSeal trays, in the hopes of offering a barrier-lined, paperboard alternative to conventional MAP and VAP trays.

The new PaperSeal tray solution reportedly utilises 80-90% paperboard and 10-20% film, depending on tray dimensions. GPI says that the paperboard is produced from renewable fibre sourced from sustainably-managed forests and the tray is apparently designed for the film liner to be easily separated from the paperboard after use, such that the paperboard portion of the tray can be recycled, contributing to a circular economy.

The PaperSeal tray offers a “unique” reinforced flange design that seeks to generate a robust and consistent sealing surface, reportedly ensuring seal integrity equal to traditional plastic trays.

The company says that its hermetically sealed PaperSeal tray is suitable for a range of applications including cheese, fresh or processed meat, ready-made products, frozen foods, snacks, salad, and fruit, providing up to 28 days of shelf life depending on the application.

Paul Tye, business development director, Graphic Packaging Europe said: “The transition to fibre-based packaging is a priority for many of our customers, and it’s clear that sustainable paperboard packaging solutions must meet the functionality and performance of existing tray designs.”

Developed in conjunction with G. Mondini, world leaders in tray sealing technology, the PaperSeal tray has an innovative design that GPI says delivers significant line efficiencies for high-volume packaging and can be stacked flat for logistics and inventory, further reducing the carbon footprint of the supply chain.

Leading European food processor ABP Food Group was one of the primary drivers behind the project. The UK company, which has been supplying retailers, wholesalers and foodservice providers with quality beef for over 60 years, has partnered with Graphic Packaging to reduce environmental impact by delivering sustainable processes throughout the supply chain.
