Multi-ply paper products and methods for manufacturing such products are provided. A method includes producing a foam of water, air, a foaming agent, uncooked starch, and a dry strength agent; applying the foam to a first surface of a base embryonic ply web; providing an applied embryonic ply web having a first surface and contacting the first surface of the base web with the first surface of the applied web at an interface to form a combined ply web; and selectively applying vacuum pressure to a second surface of the base web to retain particles of the uncooked starch on or near the first surface, to draw molecules of the dry strength agent into the base web and/or to the first surface of the applied web to retain particles of the uncooked starch in the interface and to draw molecules of the dry strength agent into the applied web.
