摘要： Paperboard having a water-repellant coating which includes a polymer matrix/wax/pigment mixture and is applied to the paperboard as an aqueous formulation. The polymer matrix includes polymer chains which are ionically cross-linked through pendant carboxylic acid groups to provide, together with the wax and pigment components, a substantially continuous, water-repellant film which more readily breaks down under the alkaline conditions of repulping. The coated board also exhibits low slip and resistance to blocking, and is particularly well-suited in corrugated box constructions used in shipping containers for perishable food items such as meats, poultry, fishery products, fruits and vegetables. The pigmented or unpigmented coating formulations are also used as an overcoat over preprinted paperboard surfaces to simultaneously provide scuff and water resistance.
