Harpak-ULMA launched its innovative PaperSeal packaging technology to promote green packaging alternatives across the food industry. Trays are produced with renewable fiber sourced from sustainably-managed forests and can employ a variety of striking, innovative designs for retail presentation. Each tray utilizes 80-90% paperboard and 10-20% film, depending on tray dimensions—dramatically reducing plastic use and limiting base tray waste to just 2%—the lowest in the industry today. In addition, the tray film liner is easily separated from the paperboard after use, allowing for the paperboard portion to be recycled.
A unique reinforced, one-piece flange design makes sealing surface strength and consistency equal to traditional plastic trays, as well as facilitating automated paperboard de-nesting—a pain point in other paperboard solutions. Trays can be stacked flat for logistics and inventory. The hermetically sealed tray provides up to 28 days of shelf life depending on the application, making it suitable for a wide range of applications including cheese, fresh or processed meat, ready-made products, frozen foods, snacks, salad, and fruit.
