Barrier coating method for porous substrates
The patent application (Publication Number: US20230366152A1) describes a method for barrier coating a porous substrate, involving coating the substrate with an intermediate layer that fills pores and then applying a non-polymer barrier layer. The non-polymer materials used for the barrier layer include metals, metal oxides, metal nitrides, metal sulfides, carbon-based materials, silicon, silicon oxide, and silicon nitride. The substrate, typically made from fibrous materials like cellulosic or pulp-based materials, has an average pore size of less than 500 um. The intermediate layer, which can be made from biopolymers, starch, natural waxes, resins, or cellulosic materials, is applied as a fluid using methods like printing, dipping, or spraying.
Furthermore, the method includes treating the intermediate layer to enhance adhesion before applying the barrier layer, which is typically made from materials like aluminum or silicon oxide. The barrier layer is applied using vacuum deposition techniques like thermal evaporation or sputtering and has a thickness of no more than 500 nm. The patent also covers a barrier material comprising the porous substrate, intermediate layer, and barrier layer, with specific compositions and weight percentages outlined. Finally, the patent extends to articles like food or beverage containers made from the described barrier material, emphasizing its potential applications in packaging industries.
