Packaging companies are increasingly focusing on sustainability and regulatory compliance through material innovation and structural engineering.

Initial developments include Progroup working toward material reduction targets and Sorma Group adapting to Europe’s Packaging and Packaging Waste Regulation (PPWR) by introducing mono-material net packaging and reducing unit weight. 

Subsequent advancements highlight the rise of fiber-based solutions. At PACK EXPO International 2026, collaborations between Michelman, UPM Specialty Materials, and BOBST introduced paper-based flexible packaging and bio-based, plastic-free coatings designed to meet standards like California’s SB 54 and the EU’s Single-Use Plastics Directive. Additionally, ProAmpac developed custom fiber-based trays for retail food applications to improve heat and moisture retention.
