Harpak-ULMA launched its 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 designs for retail presentation. Each tray utilizes 80-90% paperboard and 10-20% film, depending on tray dimensions—reducing plastic use and limiting base tray waste to just 2%. In addition, the tray film liner is easily separated from the paperboard after use, allowing for the paperboard portion to be recycled.
A reinforced, one-piece flange design makes sealing surface strength and consistency equal to traditional plastic trays, as well as facilitating automated paperboard de-nesting. 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.
