Abstract: Methods of improving dewatering efficiency, increasing sheet wet web strength, increasing sheet wet strength, and enhancing filler retention in a papermaking process are disclosed. The methods improve the efficiency of drainage aids, wet web strength aids, and/or wet strength aids by coating at least some of the filler particles with a material that prevents the filler materials form adhering to a those additives.

Abstract: The invention provides a method of improving dewatering efficiency, increasing sheet wet web strength, increasing sheet wet strength and enhancing filler retention in a papermaking process The method improves the efficiency of drainage aids or wet web strength aids or wet strength aid by coating at least some of the filler particles with a material that prevents the filler materials form adhering to a those additives. The drainage additive or wet web strength additive or wet strength aid holds the cellulose fibers together tightly and is not wasted on the filler particles.

Abstract: A laminated film (10) for application to a substrate (30) comprises at least a base layer (12), formed from an organic polymer, and an adhesive layer (16). Gamma or electron beam irradiation is applied at least to the base layer (12) to modify the polymer structure thereof, thereby strengthening the laminated film (10) and the substrate (30) to which it is applied. Glass substrates to which the laminated product is applied demonstrate improved fragment retention in the event of an impact.
