Production of Three-Layered Testliner with a White Layer by Aerodynamic Middle-Layer Molding Technology

Аннотация

Experimental data on molding of three-layered paperboard testliner from secondary fibre with an aerodynamically formed middle layer are presented. The layer-wise optimum ratios of low-quality fibres in the three-layered testliner with an aerodynamically formed middle layer for reducing paperboard production cost are given. The experimental data show the advantage of introduction of aerodynamic molding technology.
