Harpak-ULMA launches plastic-reducing packaging technology

Harpak-ULMA has launched its PaperSeal packaging technology as part of the company’s initiative to fundamentally rethink packaging systems to promote green packaging alternatives across the food industry.

Public concerns, regulatory actions, and powerful consumer trends such as eCommerce highlight the hefty environmental price of single-use packaging waste. Consumers have strongly embraced ubiquitous, convenient single-use packaging, and proponents point to its role in minimizing food waste and maintaining freshness at low cost. Replacing traditional substrates with plastics better accommodates consumers’ demand for convenience, but much of today’s multi-material packaging cannot be reprocessed with existing recycling systems. The complexity and challenges associated with plastics recovery emphasize the importance of reducing overall plastics volume by substituting innovative, renewable single-use packaging material and methods.

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.

Implementation

Structural impediments in the current industry supply chain can actually impair the adoption of sustainable packaging materials and methods, said Jerry Rundle, vice president of sales for Harpak-ULMA’s tray packaging lines.

“Entrenched producers are using hundreds of millions of plastic trays each year,” Rundle said through a press release. “They’re embedded in long-term supplier contracts and vested in the associated packaging equipment. To say that changing direction is difficult is a bit of an understatement — it’s like turning the proverbial aircraft carrier. There’s just too much industry resistance. On the other hand, new market entrants don’t have those constraints. For example, new plant-based meat companies are adopting sustainable paper-based tray packaging materials and methods out of the gate because they’re not embedded in the status quo.”

Rundle has had his share of experience attempting to overcome such impediments. Harpak-ULMA has promoted G. Mondini’s new line of PaperSeal trays as a sustainable alternative to plastic trays, he explained. This innovative packaging concept is the result of a global collaboration between G. Mondini and Graphic Packaging International, which officially launched the new line in North American markets this past February, and in Europe in May 2019.

“Graphic Packaging has more than 10 line placements already producing commercial products for multiple customers throughout Europe and Asia,” said David Devenport, vice president, consumer products and convenience for EMEA at Graphic Packaging International. “This has been achieved in less than 12 months from launch and the momentum is building.”
