Can we solve the flexible film recovery puzzle?

Multilayer, mixed-material flexible film packaging is a sustainability conundrum. Lighter in weight, using less material, and resulting in fewer greenhouse gas emissions than alternative packaging formats such as glass, aluminum, and rigid plastic, flexibles seem like the most eco-friendly packaging choice. But, unlike glass, aluminum, and rigid plastic, mixed-material flexible film* cannot be recovered at end of life.
