Compostability is growing option in the category of sustainable solutions for flexible packaging disposal. In order to be certified as compostable a multilayer structure must pass ASTM D6868 which requires that the various components must be compostable and not adversely affect the compostability of the total structure. Water based laminating adhesives further increase the sustainability attractiveness by reducing the environmental and health impact over solvent based adhesives in the area of solvent emission/exposure and low molecular weight component migration in the laminated product. Water based adhesives can typically be utilized with machinery designed for solvent based adhesives but do require special considerations.
