Material selection plays an important role in sustainable packaging design. Brands are exploring recyclable material options, post-consumer recycled (PCR) plastics, and simplified packaging structures.
Mono-material designs can make material separation easier, depending on the product structure and local recycling systems. However, sustainability should be evaluated across the entire package, including pumps, springs, closures, and other components.
The goal is not simply to use fewer materials, but to choose materials and structures that balance performance, appearance, and end-of-life considerations.
