And consumers can now drop off flexible packaging for recycling at retailers like Walmart, Target, and others. The collec tion of flexible packaging is also economically viable when materials are concentrated at specific sites where large populations of people discard packaging, such as hospitals, prisons, schools, and sporting venues. Converting flexible packaging materials from multilayer structures into recyclable flexible PE, how ever, presents technical challenges and takes one to three years. Because of the inherent property differ ences between existing multilayer structures and store drop-off recyclable PE, the conversion process includes redefining: • Production aspects. To compensate for lower tensile strength and melt temperatures asso ciated with PE, the production speeds, sealing temperatures, and sealing jaws require alter ations such as cooling sequences. • Product reformulations. To compensate for a switch to a lower-barrier PE, preservatives may need to be added to maintain food shelflife. • Logistics. To allow for shorter shelf life, the pro duction run frequency, shorter production runs, and distribution dynamics should be considered. • Finances. Higher material costs are associated with using more PE because a thicker layer of PE is required to mimic the mechanical proper ties of a thinner optimized multilayer structure. • Environmental, social, and governance or similar analysis. The implications of using thicker PE vs. nonrecyclable multilayer but less overall polymer film must be assessed. • Reclose features. To maintain a reclose feature with the higher degree of stretch associated with PE compared with other materials, sometimes In a collaborative effort, Charter Next Generation is hoping to help catalyze a circular economy for flexible films in the Upper Midwest.

Many reclose features, such as Pepperidge Farms Goldfish crackers packaging, rely on the dead fold properties of paperboard. If this package were converted to a store drop-off PE, the current dead fold-based reseal feature would not function. Localized Polymer Film Recycling and Reuse The favorable economics and sustainability benefits of recycling film regionally, and then manufacturing new film with the recycled resin, are aiding efforts on the ground. A recently announced collaboration among the MBOLD coalition, film manufacturer Charter Next Generation, and film recycler Myplas USA, for example, exemplifies the critical push and pull needed to secure films for recycling and use the recyclate from the film on a regional basis. The collab oration includes a $9.2 million joint equity investment in Myplas USA by General Mills, Schwan's, Target, Ecolab, and Charter Next Generation. Slated to be completed in spring 2023, the 170,000-square-foot Myplas USA recycling facility in Minnesota will be able to recycle 90 million pounds oflow- and high-density PE packaging and film annually. In addition, Wisconsin-based Charter Next Generation has an off-take agreement to purchase the bulk of Myplas' resin in the initial years of operation. Although more than 12 billion pounds of plastic are used annually in the United States, only 5% gets recycled, according to JoAnne Berkenkamp, manag ing director ofMBOLD. At the same time, demand for high-quality recycled resin is building as com panies work to expand the use of recycled content. "This is the challenge MBOLD and our part ners are taking on with our new circular economy initiative," says Berkenkamp. "By collaborating across the value chain from film recycler to film manufacturer to end-users, MBOLD is catalyzing a circular economy for flexible films in the Upper Midwest. We believe this is the beginning of a new model for regionally based circular economies." Improving Paperboard Recycling Connecting recyclable paperboard to the end use of the recyclate is also critical for achieving increased paperboard recycling rates and recycled content use. As with polymer films, various additives enhance paperboard package properties. Foreign materials, such as other packaging materials and food scraps, are often commingled with paperboard for food packaging. Other contaminants, such as inorganic fillers, starch, wet-strength polymers, wax, and coating materials, require removal in the recycling process. These contaminants make the paper 74 Food Technology I July 2022
