Formulators of barrier coatings used in paper packaging applications prioritize ingredients that complement the sustainability of the paper substrates to which they are applied. METHOCEL™ is a cellulose-based polymer that offers several features that make it ideal for use as a binder in paper packaging barrier coatings, as listed below.
METHOCEL™ is an exceptional film former that forms clear, tough, and flexible films that perform as excellent barriers. It may be used to form films in water-based formulations or, since some grades behave as thermoplastic polymers, may be cast or extruded. Compared to other binders used on the market for barrier coatings, METHOCEL™ has a unique property known as thermal gelation, which converts it into an insoluble gel or flocculates at or above the thermal gelation temperature threshold. When paper products coated with barrier coatings containing METHOCEL™ are placed in recycling streams, METHOCEL™ solids can be easily separated using liquid filtration processes. Below, an image of a solution of METHOCEL™ is shown to form precipitated solids when heated.
