AI Technical Summary
Current plastic packaging, particularly multilayer multi-material assemblies, face challenges in recyclability due to the presence of adhesive systems, which complicates recycling processes and increases environmental impact, while also requiring significant investments in machinery modifications to maintain performance on existing packaging machines.
A multilayer mono-material PE assembly is developed, comprising a high-density polyethylene (HDPE) first layer and a polyethylene blend second layer, optimized through an extrusion process, eliminating the need for adhesive systems and allowing for recycling without machinery adaptations, while maintaining durability, versatility, and chemical resistance.
The solution enables recyclable packaging with optimal mechanical properties, compatibility with existing machinery, and reduced environmental impact, achieving durability, versatility, and chemical resistance while ensuring sustainability and low-effort recycling.
