摘要： A fiber-based, plastic-free drinking cup is formed by providing a fiber-based slurry comprising a hydrophobic additive and a strength additive, then forming a drinking cup component by compressing and drying the fiber-based slurry in a form press assembly having an internal shape characterized by a conic frustum. The fiber-based slurry may include a dry pulp mixture of virgin fiber and recycled fiber, the hydrophobic additive is 1.0-10.0% of the dry pulp weight, and the strength additive is 1.0-10.0% of the dry pulp weight. In particular, the fiber-based slurry may include about 50% bleached hardwood, about 50% bleached softwood, about 2.5% strength additive, and about 3.5% hydrophobic additive by dry pulp weight.

摘要： A paper product having improved printing characteristics and a method of making the paper product. This paper product has a fibrous substrate and top layer of surface enhanced pulp fibers that is integrally coupled to the top surface of the fibrous substrate. The paper product is produced by providing an aqueous slurry formed from a blend of cellulosic fibers and water and at least partially dewatering the aqueous slurry of cellulosic fibers and water to form the fibrous substrate. Subsequently, a surface treatment formed from an aqueous composition of water and surface enhanced pulp fibers is applied to the top surface of the fibrous substrate and thereafter the treated fibrous substrate is dried to form a paper product having enhanced printing characteristics.

摘要： The present disclosure describes methods of treating cellulosic materials with compositions that allow greater retention of inorganic particles on cellulosic substrates. The methods as disclosed provide combining saccharide fatty acid esters (SFAE) with such inorganic particles and applying such combinations on cellulosic materials to eliminate or reduce the use of retention aids or binders for filler in the paper making process. Compositions comprising such combinations of SFAE and inorganic particles are also disclosed.

摘要： A method is disclosed for increasing strength properties, preferably burst strength and SCT strength, of a paper or board product. The paper or board product is manufactured from a fibrous web produced by a multilayer headbox, where an aqueous layer is formed between at least a first and a second fibre layer formed from fibrous stock suspension(s), and where feed water for the aqueous layer includes at least one cationic polymer. The method of the invention includes adding an anionic additive selected from a group comprising anionic synthetic organic polymers, anionic polysaccharides, and any of their combinations to the feed water before formation of the aqueous layer.
