Marine biopolymer coatings for compostable high-barrier packaging

Overview

MarinaTex introduces a revolutionary solution in sustainable packaging with its marine-derived biopolymer coatings. These coatings are designed to replace traditional fossil-based moisture barriers in packaging, offering a fully compostable and recyclable alternative. Harnessing the natural film-forming properties of polymers derived from plants and marine waste, these coatings achieve single digit moisture vapor transmission rate (MVTR), meeting industry standards while ensuring compatibility with paper recycling and composting systems. This innovation not only addresses the environmental impact of plastic waste but also aligns with the growing demand for sustainable packaging solutions.
