Co₂-derived compostable polyester platform for diaper applications

Overview

Loop CO2, Inc. presents an innovative CO₂-derived allyl-functionalized polyester platform designed for environmentally friendly and compostable diaper components. This technology delivers a unique combination of softness, hydrophobicity, and durability, addressing key gaps in traditional polyester products. The material can be processed into thin films or applied as a hydrophobic coating, serving as a fluid barrier while maintaining flexibility. Additionally, its amorphous and adhesive properties allow it to function effectively as a bio-based hotmelt adhesive, simplifying product architecture and reducing material use.
