Abstract: A resealable envelope is composed of a front panel and a rear panel attached to the front panel forming an interior pouch between the front panel and rear panel. A flap extends from the rear panel, the flap having an opening having an elongated width with two circular protrusions emanating from the top and bottom of the elongated width; the opening having a width greater than its height. A first adhesive has an adhesive layer on one side and a releasable surface layer an opposite side. The first adhesive is located at the top portion of the front panel such that the opening is in contact with the first adhesive when the flap is closed. A second adhesive strip is located on the outside of the flap over the opening such that the envelope is sealed when the flap is pressed against the resealable surface layer of the first adhesive.

Abstract: A web of fibrous material having windows covered by a transparent material, and which is modified by compression, shaving, or embossing, so as to maintain a substantially uniform thickness throughout the length of the web. When the web is then wound onto itself, the resulting roll will have a substantially circular cross-section.
