The invention relates to 42-47g / m < 2 > ultra-low basis weight corrugating medium paper and a production process thereof, and belongs to the technical field of packaging paperboards. Kaolin is introduced as a high-quality filler in the production process of the corrugating medium paper, and phthalimide is used as a modifier, so that the dispersity and stability of kaolin in a fiber matrix are effectively improved, the binding force between fibers is enhanced, and the overall structural strength and mechanical property of the corrugating medium paper are remarkably improved. Meanwhile, corn starch is treated by beta-amylase to prepare modified starch, so that the viscosity and the permeability of the modified starch are improved, the combination among fibers is further consolidated, and the tensile strength and the bursting strength of the corrugated medium paper are improved. Besides, polyethylene glycol and nanocellulose are added as a lubricant and a stabilizer, friction between fibers and filler is reduced, the flexibility and plasticity of paper are improved, and layering or precipitation of modified components is prevented, so that the production process is optimized, the production quantitation is reduced, and the economical efficiency and environmental friendliness of the material are improved.

The invention relates to a method for producing a fibrous web containing natural and synthetic fibers. The invention relates to a method for producing a fibrous web comprising a fibrous matrix consisting of natural fibers and possibly synthetic fibers. According to the method of the invention, a layer containing horizontal plane fibers is prepared from natural fibers and possibly synthetic fibers, the layer comprising an aqueous phase and a fiber phase, and the layer is dried to remove the aqueous phase, in which case the natural fibers and possibly synthetic fibers together form a fiber matrix. According to the invention, a binder is applied to the aqueous fibrous layer such that the binder at least partially permeates through the aqueous phase between the fibres before hydrogen bonds are formed between the fibres. Using the invention, such cellulose-or lignocellulose-based fibrous products having plastic-like properties such as good fracture toughness, tear resistance and stretch can be produced.
