Abstract: A leak proof container and a method of forming the container from a blank. The blank includes a bottom panel, first and second side panels at opposing lateral edges of the blank, and opposing end portions located at opposing longitudinal ends of the blank. Each end portion includes an inner end panel, an outer end panel hingedly connected to the inner end panel at hinge portions, and first and second corner panels, each corner panel forming a gusset between one of the side panels and the inner end panel, each gusset including a notch area for receiving one of the hinge portions. First and second locking tabs are defined in the outer end panel. The outer end panel can be folded over the inner end panel to position the hinge portions in the notch areas, and the locking tabs can be positioned between the gussets and the inner end panel.

Abstract: An insert formed from a one-piece blank of sheet material. The insert comprises a first half comprising a first plurality of connected panels; a second half connected to the first half and comprising a corresponding, second plurality of connected panels; a first and second end comprising lateral extensions extending from respective first and second opposing ends of two panels from each of the first and second plurality of panels; and a plurality of popout tabs extending outward from an outer surface of the insert. The first and second half define respective first and second internal receiving areas each surrounded on all sides and on opposing ends by (i) two layers of the sheet material and/or (ii) an air gap defined between the outer surface of the insert and an adjacent portion of an overwrap material. A one-piece blank of sheet material for forming a shipping insert is also provided.

Abstract: Methods of forming crosslinked cellulose include mixing a crosslinking agent with an aqueous mixture of cellulose fibers containing little to no excess water (e.g., solids content of 25-55%), drying the resulting mixture to 85-100% solids, then curing the dried mixture to crosslink the cellulose fibers. Systems include a mixing unit to form, from an aqueous mixture of unbonded cellulose fibers having a solids content of about 25-55% and a crosslinking agent, a substantially homogenous mixture of non-crosslinked, unbonded cellulose fibers and crosslinking agent; a drying unit to dry the substantially homogenous mixture to a consistency of 85-100%; and a curing unit and to cure the crosslinking agent to form dried and cured crosslinked cellulose fibers. Intrafiber crosslinked cellulose pulp fibers produced by such methods and/or systems have a chemical on pulp level of about 2-14% and an AFAQ capacity of at least 12.0 g/g.

Abstract: Bleached polycrylic acid crosslinked cellulose fibers with reduced furfural content are disclosed. The reduced furfural content is accompanied by a strong reduction of malodor associated with crosslinked fibers. Methods of furfural reduction include treatment with hydrogen peroxide in the absence of alkaline or other bleaching agents subsequent to curing polyacrylic acid crosslinked cellulose fibers. Some embodiments of treated polycrylic acid crosslinked cellulose fibers have a furfural content lower than 1.3 ppm. In some embodiments, the reduction of furfural content of the treated crosslinked fibers compared to untreated crosslinked fibers is at least 55%. in some embodiments, furfural content decreases with aging of the treated crosslinked fibers.
